ABSTRACT

This investigation was carried out on buffalo bones to shed light upon the gross chemical composition, amino acid contents, mineral contents, fatty acids composition of total lipids and functional properties of bone extract. Evaluation the quality, acceptability and biological value of formulated sausages, as well as manufacturing of high protein biscuits for school children feeding programme with varying levels of dried bone extract were studied. The results could be summarized as follows: 1-The raw bone contained 41.02% ash, 28.78% protein and 27.82% fat, while the bone extract

contained high level of protein 95.28%followed by fat 4.01% and ash 1.58%. The total yield of dried bone extract was26.40% of the original weight of the bones.

2-Raw bone and bone extract had higher levels of Ca, Zn, MG, and K. 3-The fatty acids composition of total lipids showed that the total unsaturated fatty acids was

49.50% of the total fatty acid. Linoleic and Linoleic acid were the predominant unsaturated fatty acids in bone lipids needed for the proper nutrition .

4-The functional properties of bone extract showed that solubility and foaming capacity were high, but oil absorption and foaming stability were low.

5-The raw bone and its extract had good levels of all essential amino acids except for methionine and tryptophan.

6-The addition of 10% and 20% of bone extract to sausages resulted in good acceptable characteristics.

7-Supplementation of biscuits for primary school students by 6% bone extract could be effectively used to alleviate the protein calorie malnutrition in school children.

ABSTRACT

The flushing of both uterine horns of 36 uterine specimens of buffalo cows free from any pathological lesions via catheter using 30 ml of phosphate buffer solution (PBS) were collected. Alkaline phosphatase (ALP) and Aspartate aminotransferase (AST) were evaluated. Significant cyclic variations (P < 0.001) of ALP activity was found in uterine flushing media. The ALP activity was significantly higher (P< 0.001) in flushing media obtained from ipsolateral horn to corpus luteum than from contralateral horn. No significant cyclic variations of AST activity was found in uterine flushing media. The results revealed that ALP activity in flushing media of buffalo cows is very low when compared with cattle and causes of this variations were discussed .

ABSTRACT

The changes in lipid peroxide and nitric oxide productions, antioxidant activities (superoxide dismutase, glutathione and vitamin E) and total lipids were studied in corpora lutea and its relation to serum progesterone levels in buffalo-cows. A total of 48 corpora lutea were dissected from ovaries obtained from local abattoir and classified according to physico-anatomy to developing, fully developed and regressing corpora lutea. In regressing corpora lutea, although, the total LPO production was higher, the NO production was lower than in developing or fully developed Cls. Moreover, LPO production was negatively correlated with both SOD and serum P4 levels, which were significant in fully developed or in regressing Cls. Superoxide dismutase activity and glutathione content were significantly higher in fully developed corpora lutea. SOD activity was significantly positively correlated with serum P4 levels in developing or fully developed Cls. Vitamin Econtent tend to be higher in regressing CL than in other stages of development of CL. However, a marked increase of total lipid content was observed in regressing CL than in developing or fully developed CL, the cholesterol levels was unchanged.

oxide production and antioxidant activities is a dynamic and regulated process, which could play an important role in regulating luteal function during estrous cycle in buffalo-cows.

ABSTRACT

The histomorphological changes in the foetal-sole of one-humped camel ranging from 8 to 125 cm CVR length was studied. In foetuses of 8 cm CVR length, the epidermis was composed of 2-3 cell layers. At 37 cm CVR length, the primary elements of stratum corneum appeared and replaced the periderm. The anlagen of stratum lucidum was observed at 85 cm CVR length. The epidermis was well differentiated into 5 distinctive layers in full term foetuses (115-125 cm CVR length). The primordia of tubular glands appeared at 18 cm CVR length. These glands increased in depth and width throughout the intrauterine life. They could be distinguished into a presumptive duct and an end- piece at 45 to 60 cm CVR length. 68 cm CVR length, the ducts were canalized and lined by two layers of epithelium. The end- pieces appeared as tubular structures, lined by 2 types of cells; inner cuboidal and outer elongated, in full term foetuses (115-125 cm CVR length).

ABSTRACT

Thirty eight samples of either fresh or pickled Domiati cheese were collected from Assiut Governorate markets. Some chemical analysis and total bacterial count (TBC) for each sample were estimated. Results obtained could be summarizer as follows : 1-Some of the samples examined of both fresh and pickled Domiati cheese did not coincide

with the Egyptian legal standard for full cream normal Domiati cheese made from cows or mixed milk regarding moisture percentage and F/DM ratio.

2-The carotene content of cheese sample could be taken as a criterion for determining the kind se is made from

(buffalo + 3-F/DM, lactose, acidity and amino N content of cheese samples could be taken as good

indicative criteria of cheese quality. Some correlation coefficients could be obtained between each criterion and some of organoleptic characters of cheese.

4-The quality control authorities must obligate the cheese producers to put the correct lable on

ABSTRACT

Selection for body weight and egg number was carried out in a population of Dandarawi chicken over four successive generations at the Poultry Farm of Assiut University. The program of selection included three lines; line B selected for body weight at 8weeks of age, line E selected for egg number at 40-weeks of age and line C randombred control. Body weight and as a shank length at 4- and 8-week of age were measured on 11913 chicks obtained from mating of 239 sires with 1762 dams over four successive generation. Results showed that variance components of body weight at 4-and 8- weeks of age from sires were higher than those from dams in both lines C and E indicating the significant influence of sex-linked effects over generations. In line B dam components were higher than sire components at 4- weeks in first and second generations but declined sharply in third and fourth generations at 8-weeks of age, At the early age in line B, maternal effects significantly affected body weight, but later on sex-linked effects influenced body weight. In general, sire and dam variance components declined over generation as a result of the increase of homogeneity within the selected lines over generations. Heritability estimates at 4- and 8- weeks of age in both lines C and E from sire components were higher than those from dam and sire and dam components may be due to the presence of sex-linked effects. In line B at 4-weeks of age, the estimates were higher from dam components within the first two generations, thereafter from sire components exceeded that from dams as at 8-weeks of age. Variance components estimates of shank length at 4-and 8-weeks of age in each line were inconsistent over generations. The sex-linked and maternal effects on shank length at 4- and 8-weeks of age were lower than those observed on body weight for all lines. Heritability of shank length at 4- and 8-weeks of age of the three lines were higher for sires than for dams or sire and dam components over generations. The inconsistent estimates from generation to generation may be resulted from sampling errors or variation in the environmental conditions. The genetic changes in the population of Dandarawi chickens during the program of selection indicated sharp decline in dam variance components than in sire components. Over generations, both sire and dam components, decline due to the increase of homogeneity of body weight and shank length of the selected lines in the population of Dandarawi chickens.

ABSTRACT

The present study was carried out on a stock of Dandarawi chickens maintained in the Poultry Farm of Assiut University. The mode of inheritance of a slow feathering gene (K) mutant has been studied in a series of crosses. Classification and segregation ratios for all progenies per genotype were recorded, The effects of slow feathering gene (K) on body weight and carcass measurements were determined compared with rapid feathering genotype. The results showed that the mode of inheritance of the mutant gene coincide with the hypothesis that the allele K on the sex chromosome was responsible for slow feathering in Dandarawi chickens. The effects of slow feathering gene on chick body weight were significant at 1 and 4 weeks of age, whereas no significant effects were noticed at 8-and 12-weeks age. At 16-weeks of age, no significant differences in body weight between rapid and slow feathering genotypes were found, however the difference due to sex was highly significant. The feathers weight as a percentage of live body weight differed significantly (p<0.01)in favor to rapid feathering birds up to 8-weeks of age. The heart weight as a percentage of body weight of slow feathering genotype was larger than that of rapid feathering genotype and the differences between genotypes were highly significant. The high percentage of heart of slow feathering genotype may be due to high metabolic rate at the growth period as a secondary effect of the slow feathering gene Carcass percentage of slow feathering genotype was lager (p<0.01) than that of rapid feathering genotype. The high carcass percentage of slow feathering genotype reflected the spare effect of K gene during the juvenile period for certain nutrients essentially needed to from muscles more than feathers. Considering the main parts of the carcass, the breast percentage of slow feathering genotype exceeded that of rapid feathering genotype and the difference between the two genotypes was highly significant. Thigh percentage of rapid feathering genotype was larger as compared with slow feathering genotype. From these results, it could be mentioned that the slow feathering gene was partially responsible for increasing the breast muscles of Dandarawi chickens.

ABSTRACT

This investigation was carried out on two of chicken slaughter house by-products namely: chicken heads and feet to prepare protein concentrates using neutral protease. Gross chemical composition, mineral contents, amino acid composition and microbiological evaluation of chicken heads and feet as well as the prepared protein concentrates were studied. Evaluation the quality and acceptability of formulated high protein biscuits with varying levels (2.4 and 6%) of protein concentrates were assessed. The obtained data showed that: 1-Chicken heads had higher content of moisture, fat, K and Zn and less contents of protein, ash,

Na, Ca, Mg and Fe than chicken feet. 2-The essential amino acid contents in chicken heads and feet were 24.72 and 26.00 g/100g

protein; respectively. Chicken feet contained more protein and glycine that chicken heads. 3-The yields of protein concentrates prepared from chicken heads and feet were 7 and 8%

respectively. That means, Egypt can produce about 133 and 182.4 tons of protein concentrates from chicken heads and feet every year.

4-Chicken head protein concentrate was colored brown and had 90.46% protein content (on dry basis), while, chicken feet protein concentrate was colored yellow with 93.97% protein.

5-The prepared protein concentrate were none bitter taste and had considerable amounts of elements and high caloric value.

6-Essential amino acid contents were 25.93 and 26.64g/100g protein for head and feet protein concentrates respectively.

7-The total bacterial counts were27X102 and 44X102 CFU/g for head and feet protein concentrates while no coliform bacteria was detected in the two types of concentrates.

8-Addition of the prepared chicken head and feet protein concentrates to biscuits formula at percentages of 2, 4 and 6% of flour weight improved the organoleptic quality of biscuit and its overall quality.

From the obtained data it could be concluded that chicken by-products, which up to now have been used as wastes might be very useful for preparation of edible protein concentrates and could be used in many food purposes.

ADDRESS : Dept. of Otolaryngology, Unit of Phoniatrics, Faculty of Med., Assiut Univ.

BULLETIN : Assiut Med. J. Vol. 22, No., 3, 1998 .

ABSTRACT

The communication proficiency relies on the structural and functional integrity of the phonatory and articulatory systems as well as the complex symbolic system (i.e., language). Accordingly, these 3 systems may be disrupted resulting in voice, speech and language disorders. Children represent a specifically vulnerable group for various communication disabilities due to maturation problems in this particular period of life. However, services for such children in many less developed countries are extremely limited. For appropriate services to be developed, information is required about the size of the problem, existing skills and services. In this regard, there are few published surveys that describe the pattern of communication disorders especially among Egyptian population because such surveys are expensive and time consuming. Therefore, this study represents an alternative way of gathering such information for sensitizing health professionals to the nature of communication disorders. In turn, this might be useful in the planning and development of rehabilitation services for a communicatively handicapped child. Data were collected from the hospital records of the proportion of children with communication disorders who presented themselves to Unit of Phoniatrics in Assiut University Hospitals, Assiut, Egypt in the last 7 years (Dec., 1990- Dec. 1997). For each child, the demographic characteristics, medical antecedents, cause and diagnosis of communicative disability were collected. The results were analyzed in the context of the possibility of determination of the factors conducive to the occurrence of communication disorders and the factors which should contribute to future improvement of services for the communicatively handicapped child .

ABSTRACT

The present study deals with stratigraphy, macropaleontology, palaeoecology and depositional environment of fossiliferous Upper Cretaceous - Lower Tertiary succession exposed at the Darb El-Arbain area, south western desert, Egypt. The study area lies between the Gebel Abu Bayan El-Qibli (South of Beris) at the North and Bir-Murr at the south. It is located between the longitudes 30° 00` and 31° 00` E and the latitudes 23° 20` and 24° 20` N . The present study is based on stratigraphical and paleontological as well as sedimentological analyses of geological data collected from three columnar sections measured at Bir Murr, Gebel Shirshir and Maqtal El Darawish localities, Darb El-Arbain area. Examination of the collected macrofauna has led to identification of 35 species belonging to 4 classes, 20 families and 24 genera. The 35 species consist of 17 bivalves, 15 gastropods, one cephalopod, and 2 echinoderms. This fauna links the study area of the Egyptian Western Desert with other areas of the Mediterranean Province of the Tethyan realm . Based on vertical distribution of the macrofauna, six molluscan biozones are established. They are, from base to top: 1-Exogyra overwgi - Lopha bomilcaris zone. Late Maastrichtian. 2-Venericardia quassi - Chlamys acuteplicatus zone Late Maastrichtian . 3-Venericardia libyca - Avellana chargensis zone. Late Danian . 4-Venericardia wegeneri - Ostrea orientalis zone. Late Danian . 5-Pycnodonte simile zone. Late Danian . 6- Ostrea osiris zone. Late Paleocene (Thanetian) . Depositional environments of the fossiliferous Maastrichtian-Paleocene succession exposed in the study area have been interpreted on the basis of : 1-Biostratinomical analysis of certain shell beds 2-Microfacies analysis of the carbonate beds. 3-Benthic macrofossil assemblages. 4-Palaeoecological and palaeobiogeographical significance of the macrofauna. 5-Species diversity curves .

ABSTRACT

Roughage sources were compared in diets contained 40% Egyptian clover (Berseem) or with corn stover or rice straw replaced half of the Berseem. Latin square experiment was used to test the effect of roughage sources on milk yield, composition, body weight change and chewing activity in six lactating Jersey cow in late lactation. There were no change (P>.05) in milk yield or 4% FCM due to treatments. Although, milk composition was not affected by treatments (P>.05), milk fat % was 0.3% unit higher in rice straw diet and 0.1% unit in corn stover diet than that of the control diet . Treatments had no effect on body weight. Rice straw diet increased (P<.05) rumination time by 29% than the control one. Corn stover diet had 21% more rumination time than the control (P<.05). The difference in rumination time between treatments was not significant (P>.05). Eating time as well as lag time were longer (P<.05) in the control diet than the other test diets. Rumination expressed as min/kg roughage intake daily follow trends similar those for time spent ruminating min/day. Total chewing min/day or min/kg roughage/day were longer for rice straw diet than both corn stover and controldiets . These difference were significant between rice straw and control diets only. These results indicated that low quality roughage could replace half of the berseem with effect no milk yield, composition or animal health .

ABSTRACT

Two trials were conducted to study the extent to which the broilers are in need for animal protein. The effect of all plant protein diet (C/SBM) and meal (FM) supplemented-ones was tested in relation to the bird performance. One day-old Arbor Acre broiler chicks were used in trial 1 to trace the effect of 10 treatments for 7 weeks feeding period. 7,4 & 2% FM diets, C/SBM with extra vitamins (AD3

were conducted in a trial and the level of 7% FM was tried to be fed for 1, 2, 3, & 4 weeks of age and compared with the same level along the whole fattening period in another trial. All FM diets were surpassing the C/SBM diets in stimulating the growth together with increasing the efficiency of feed conversion and the 4% level was the optimal one. The C/SBM diets failed to satisfy the needs for growth and to protect the chicks against nutritional disorders, were leg disorder was appeared in the chicks. However, rapid growth was achieved if the supplementation with the FM was confined to the first 3 or 4 weeks of age. FM diets in spite of being costy, it is proved to be more economic .

ABSTRACT

Comparisons between males and females in each of Assiut and Aswan samples and between Assiut and Aswan combined sex samples of A. nurse were possible on the basis of the mean values and mode of variation of some of their morphometric indices, Morphometric characters reliable for taxonomic purposes and for the differentiation between such samples were determined by making use of the significance of differences between the regression coefficients of some of the morphometric measurements and between Y-intercepts of regression lines of such measurements from zero value. The coefficient of difference (C.D.) between the morphometric indices of Assiut and Aswan samples of A. nurse considered did not attain the value of 1.28. Accordingly, populations of A. nurse of those localities did not represent a subspecific status; they could be only considered as geographical races or isolates.

ABSTRACT

A comparison of scale characteristics of A. nurse and A. baremose has demonstrated species differences valid for taxonomic purposes . In A. nurse, the posterior field of the scale contained many broken circuli continuations behind the focus. In A. baremose, the circuli mostly ended abruptly at the anterior margin of the posterior field of the scale and seldom invaded that field at their bases by brief continuations. Pits and granular asperites were present in the posterior field of scales of A. baremose but were lacking in the corresponding field of A. nurse scales. The presence of a branch of the lateral line canal in the posterior field of the posterior most lateral line scale was a diagnostic feature which characterized A. baremose from A. nurse .

ABSTRACT

A regression- adjustment equation was used prior to the application of principal components analysis on some morphometric characters of certain Nile mormyrid populations. The results obtained by the application of such an equation were compared with those obtained in a previous study on the same populations using another equation. It was concluded that the proposed equation led to the elimination of the ontogenetic size components and the identification of the remainder ones including geographic, racial and sexual. The importance of applying the proposed regression-adjustment equation for a comprehensive study of size and shape was discussed.

BULLETIN : Assiut Vet. Med. J., Vol. 26, No. 51 , October 1991

ABSTRACT

The bivariate size allometry of Chrysichthys auratus was estimated by the application of the power function equation of Huxley (1932) on certain morphometric characters in terms of its parameters. The bivariate allometric concept was expanded for multivariate data by Jolicoeu

test. Also, the allometric nature in the morphometric indices of the species studied was determined and discussed. According to the patterns of bivariate and multivariate allometry exhibited, sexual dimorphism and racial differences in Chrysichthys auratus were evident.

BULLETIN : Assiut Vet. Med. J., Vol. 26, No. 51 , October 1991

ABSTRACT

The principal component analysis (PCA) of certain raw morphometric and meristic characters of Alestes nurse from the main course of the Nile at Aswan (latitude 24°) and Assiut (latitude 27°), Egypt led to the presence of certain size morphometric forms and meristic forms. Moreover, by variable position of such an analysis, it is concluded that the relative variable position of the dorsal fin led to the recognition of three morphometric shape forms. By the application of PCA and canonical variates analysis on certain shape characters in addition to the above ones, racial and sexual variations of Alestes nurse were revealed. Moreover, the racial variations in the meristic characters of that species from different African areas were compared.

ABSTRACT

Certain biological aspects of males, females and combined sexes of Oreochromis niloticus from Lake Nasser, Egypt were studied. The length-weight relationship of males and females was found to be isometric whereas that of the combined sexes was allometric. Females were heavier than males. The condition factor - revealed monthly variations and sexual dimorphism but did not show any particular trend with the increase of fish size. The time of minimum increment of the annulus formation was found to be in August, January and April for males, females and combined sexes respectively. The growth rate showed sexual dimorphism in terms of annual increments of length and weight. The survival rate of females was higher than that of males.

ABSTRACT

In Egypt and Sudan, intra-and inter specific differences in the growth of two sympatric Bagrus species in relation with river/lake characteristics were revealed. Theoretical growth and survival, mortality and instantaneous growth rates of Begrus bajad (B. bayad) and B. docmak were estimated in different geographical regions of Egypt (Nozha Hydrodrome, Bahr shebeen, Assiut, Lake Nasser) and Sudan. Sexual dimorphism and geographic variations of those characteristics were evident. B. docmak exhibited better growth in length than B. bajad in Sudan, whereas the reverse was the case in the Nile at Assiut and Lake Nasser. In Assiut and Sudan B. docmak was heavier than B. bajad whereas in Lake Nasser the reverse was evident. The inter specific differences in weight of Sudan fish populations increased as age increased whereas in other regions such differences were almost constant with age increase.

ABSTRACT

In the present investigation, the historic catch-effort and water level data and the previous studies in 1966-1992 period were collected and analyzed to assess the potential yield and to determine the current status of Lake Nasser fisheries with special emphasis on those of Oreochromis niloticus and Sarotherodon galilaeus. The effect of hydrological regime on the catch-effort data was formulated in univariate and multivariate senses and discussed to interpret the reasons of species decline on the light of other environmental factors. Moreover, the impact of such regime on recruitment was considered. The relationship between the catch of O. niloticus and S. galilaeus and gonad index was evaluated. The prohibiting of fishing was discussed on the light of the variations in the gonad-index and sexual maturity. The relationship between the catch per unit effort (CPUE) and effort of different commercial fish groups (Tilapiines, Hydrocynus, Lates, Bagrus, labeo and Clarias spp) were analyzed and discussed using different mathematical models. Accordingly, the maximum sustainable yield (MSY) and the corresponding optimum effort were determined for these groups of fishes with special emphasis on O. niloticus and S. galilaeus. The catch-effort and growth data of O. niloticus and S. galilaeus of Lake Nasser were subjected to virtual population analysis (VPA),Age-based Thompson and Bell model, yield per recruit and relative yield per recruit models -recruitment model. Accordingly, the abundance, biomass, production, turnover rate, pattern of recruitment, pattern of yield per recruit, the effect of age at first capture, mortality in the pre-recruit stages, egg production per recruit and stock-recruitment relationship were estimated and/or formulated. Also, life tables and survivorship curves were built up and discussed. Gear selectivity and the optimum length of trawl gears and current trammel nets for O. niloticus and S. galilaeus were derived from VPA and analysis of experimental catch.

ADDRESS : Dept. of Animal Hygiene, Faculty of Vet. Med., Assiut University.

BULLETIN : Assiut Vet. Med. J. Vol. 40, No. 79, October 1998.

ABSTRACT

In this study two experiments were conducted to test the possibility of replacing fish meal protein partially or completely by other protein sources in the commercial diets of tilapia (O.niloticus). These were, the poultry by-product meal (PBPM) and the dried earthworm meal (EWM). In the two experiments, fish meal protein was substituted by poultry by-product meal protein (PBPM) in the first one and earthworm meal protein (EWM) in the second at an levels of 0, 25, 50, 75 & 100% for the two products. In each experiment, 150 O. niloticus fish were divided into equal 10 groups (15 fish/group) and the fish were fed to satiation on the experimental diets for 60 days. In the first experiment, there was nogreat difference between diets containing 25% and 50% PBPM and their performance was better than the control diet, 75% and 100% PBPM. Feed intake was decreased in fish groups fed on the high levels of PBPM replacement (75 & 100%). Protein efficiency ratio (PER) and protein retention of the fish group fed on 25% and 50% PBPM were higher than the control group and the lowest values with 100% PBPM substitution. Apparent protein digestibility (APD) in the diets did not differ greatly and varied from 75% to 84%. In the second experiment, feed intake was decreased in fish groups fed on the all diets including EWM when compared to the control group fed on the fish meal. Fish fed on the control diet had the highest growth rate and feed utilization, while those fed on 100% EWM protein diet were the poorest. The PER & APD of the control group were higher than for fish fed on EWM protein diets. It could be concluded that, the protein of PBPM could be improved when it replace partially of fish meal protein, while the use of EWM has adverse effects on the productivity of fish even at low percentage.

ADDRESS : Dept. of Animal Production, Faculty of Agriculture, Assiut University.

BULLETIN : Assiut Vet. Med. J. Vol. 40, No. 79, October 1998.

ABSTRACT

In the present work, the effects and validity of poultry droppings (PD) addition to fish diet, supplemented with 3g ascorbic acid (AA) /kg diet and 10% live yeast (LY), on the production of Oreochromis niloticus were studied under different experimental conditions. Such effects were evaluated in terms of different parameters including growth performance, muscle composition, blood constituents and thyroid hormone levels. Fish diets containing four different levels of poultry droppings (10,20,30 and 40%) were considered and evaluated in comparison with the basal diet (the control). The dietary ascorbic acid (AA) and live yeast (LY) improved (p<0.05) body weight. Moreover, with the addition of 3g AA/kg diet and 10% LY the body weight gain and body length increment did not differ significantly (P>0.05) in fish fed the diets containing 10,20,30,and 40% poultry droppings in comparison with fish fed the control one. Also, AA and LY improved (P<0.01) HSI and slightly increased female GSI Addition of AA and LY had no effect on crude protein in muscles whereas such addition reduced fat, moisture and ash percentages in muscles (P<0.05) AA and LY led to significant increase of Hemoglobin, serum glucose, albumin and T3 and decrease in serum cholesterol. While, PCV%, serum total protein, globulin, A/G ratio and urea- N levels were not affected, These findings were discussed and it is concluded that the addition of ascorbic acid (AA) and live Yeast (LY) improved growth performance and counteracted the increased percentage of poultry droppings added to fish diet. This make the diet with increased percentage of poultry droppings to be practically and may be one of the most suitable commercial diets for Oreochromis niloticus under subtropical environmental conditions prevailing in Upper Egypt.

ABSTRACT

The study was carried out in the Experimental Farm, Faculty of Agriculture, Assiut University. The study started at 1st of December 1985 until 1st of December 1986 on 9 does (5 Egyptian Baladi and 4 Anglo-Nubian crossbred goats) for determination of estradiol 17B (E2 Quant) and Progesteronc hormones. Goats fed the available green fodder throughout the year by grazing plus pelleted concentrates 1kg/head/day. Two hundred seventy blood samples had been taken during 7 oestrus cycles in January (winter), April: May (spring), July (summer) and October (autumn).

The obtained results summarized as follows: Progesterone hormone concentration in blood serum showed significant difference between the two studied breeds and between individuals within each breed (P<0.05). The oestrus cycle overall mean was 2.4+0.2 ng/ml blood serum of Egyptian Baladi v.s. 1.4+0.2 ng/ml blood serum of crossbred. The lowest level of the concentration occurred on the day (0) of oestrus cycle in both breeds, it was 0.7+0.02 and 0.5+0.04 ng/ml blood serum, respectively. The maximum concentration was recorded on days 14 and 10 after oestrus in Egyptian Baladi and crossbred with averages of 5.4+0.8 and 3.1+1.5 ng/ml blood serum, respectively. There were significant differences (P<0.01) between the two studied breeds and between individuals within each breed in the estradiol 17B level during oestrus cycles. The overall mean of the estradiol 17B was 35.88+3.3 pg/ml blood serum in Egyptian Baladi v.s. 22.0+1.6 pg/ml blood serum for crossbred. On the other hand, there was no effect of season on estradiol 17B concentration. The maximum level of hormone was recorded on the day (0) of oestrus; Being 65.0+9.2 and 47.7+6.4 pg/ml blood serum for Egyptian Baladi and crossbred, respectively.

ABSTRACT

Shelter is one of the basic needs for people. It is also a basic right that any human being may claim. Therefore, low-income housing is an important, if not the most important, part of the urban problem in Egypt. This is due to the considerable proportion of low income groups, who represents the vast majority of urban population, On the other hand, the limited economic ability of low-income groups hinders their accessibility to housing opportunities . the main obstacle against a suitable shelter lies, then, in the widening gap between the sharp rise in construction costs and the limited income of the majority of urban population. The result is, thus, manifested in a considerable shortage of a proper accommodation for the majority . This paper is an endeavour to propose an alternative construction material, and an innovative construction method that would substantially reduce the cost of construction. the paper propose is the use of date palm fibres, which is available in Egypt in abundance, as a reinforcement for a concrete roofing element. Components of such an element would, thus, be cement, sand and date palm fibres .

ABSTRACT

The common smut disease was observed in maize fields of Assiut locality on 30th July 1991 and 1992 successive seasons when the average of daily air temperature and relative humidity (R.H.) were 31.2°C and 46.5% R.H. in 1991 season and 30.5°C and 51% R.H. in 1992 season. Maximum disease incidence (14.3-16.7%) was on 15th September in both seasons when air temperature and R.H. were 26.3°C and 54.5% R.H. in 1991 season and 26.7°C and 58.5% R.H. in 1991. Application of nitrogen (N) and potassium (K) fertilizers in both localities, affected incidence of the disease and grain yield of the cultivar Giza 2, while application of phosphorus (P) fertilizer affected only grain yield. In general, grain yield of the tested cultivar, in both localities, was increased by increasing N, P and K levels, while the incidence of the disease was increased by increasing N levels and decreased by increasing K levels.

ABSTRACT

Proximate chemical composition, oil characteristics, total lipids; triglycerides fractionation and fatty acids composition of an Egyptian variety of okra seeds namely, Baladi were investigated. Okra seeds contained 21.29% crude oil with iodin value of 88.97.total lipids were fractionated to nine fractions. Triglycerides constituted 75% of the total lipids followed by diglycerides which recorded 6.5%. Using TLC, triglycerides were fractionated to six fractions. Total unsaturated fatty acids of okra seeds oil was about 61%, while total saturated fatty acids value was about 39%. Okra seeds oil contained relatively high level of palmitic acid (36.9%) Linoleic and oleic fatty acids constituted 32.6 and 27.7% of the total fatty acids, respectively. However, okra seeds oil has similar characteristics of the other edible used oils and may be used to meet the demands of the great shorting in edible oils in Egypt.

ABSTRACT

o (Lycopersicon Esculentum Mill.) set both seedless and seeded fruits under the fluctuating temperatures prevailing during late March and early April in Assiut district, Egypt. Entirely seedless fruits developed under the low temperatures prevailing during Dec. Seedless fruits developed without stimulus pollination. All seedless fruits were normally jelled, and appeared similar in shape and size to the seeded fruits. Study of F1, F2, and backcross

-8expression of the trait was due to a recessive gene. No genetic linkages for parthenocarpy were detected with type of growth habit and leaflet lobation. Under stressful low temperatures prevailed during the whole flowering period in late winter season, the two non parthenocarpic cvs. Were fruitless. F1 and backcrosses to non parthenocarpic parents, which had no expression for parthenocarpy, were also fruitless under these growing conditions. On the other hand, fruit set was observed on plants expressing parthenocarpy in F2

2 and BCP populations which had only about 25% and 50%, respectively, of their plants producing fruits. Potentially useful parthenocarpic segregates were found in F2 of the two crosses for increased fruit weight of normally shaped and jelled fruits.

ABSTRACT

The study was conducted during 93/1994, 94/1995 in the farm of Assiut University, two separate experiments were included . The first experiment contained 14 ecotypes collected from different regions of Egypt and two distances (5, 20 cm) between plants and two levels of cuttings viz, 5, 10 cm above ground surface. The experiment was planted in three different dates namely, Feb. 1, April 15 and October 1. Result showed that there were significant differences among ecotypes in yield and other studied characters such as, branching abiliy, plant height, green leaf yield, leaf : stem ratios %, dry matter content in leaves and stems and other characters. Moreover, close distance between plants gave higher yield, branching ability, green and dry leaf than wide spacing, level of cutting had a significant effect on yield, ability of branching and most other studied characters. Cutting in the 3rd planting date had a harmful effect on branching ability so that none of the ecotypes could start growth again. 2 second experiment was designed

In the Faculty of Agriculture Research Farm, Assiut University, Assiut, Upper Egypt, throughout successive planting dates of 1992, 1993 and 1994. Survey of aphids was achieved on three crops, cucumber, potato and artichoke. In the present study, the species composition of alatae and apterous aphids was determined. The work also describes the effect of planting dates on the seasonal abundance of certain aphid species alighting or colonizing the three crops. An indentification key for winged aphids was made to enable to identify 30 species which were found in Assiut .

ABSTRACT

A total of 90 somaclones were regenerated from tissue culture of the sugarcane variety C-310 and established in the field. The vegetative progeny of these somaclones and their donor parent were grown in the second season and at the harvest time, they evaluated for stalk number, length, diameter, volume sugar content (T.S.S %) and estimated yield. Highly significant differences among the tested somaclones were observed for all studied characters. Some somaclones were more vigorously than the donor parent in the studied characters at different magnitude. In this connection, one somaclone exhibited significant development in all studied characters, as compared with the parent C-310. In addition, two somaclones were more vigorously than the parent in stalk number, length, diameter, volume, and estimated yield. However, 13,14,3 and 12 somaclones were exceeded their donor parent in one, two, three and four characters, respectively. Higher heritability estimates were found for stalk length (95%), stalk number and estimated yield (73%) and stalk volume (72%). However, a moderate and low heritability estimates were recorded for sugar content (51.0%) and stalk diameter (32.0%), respectively. The clones obtained in the present study with elevated vigorous in one or more characters indicating that such technology could be used as a potential and powerful tool in the rescue and renewal the old degenerated sugarcane valuable germplasm, and the establishment of potentially new clones from them not only identical to its parent in most respects, but also have acquired enhancement of one or more character such as yield components, disease resistance and/or stress tolerance. Computer analysis of protein profiles revealed that the somaclones differed from each parent in one more protein bands, which suggested that they differed from each other as well as from the donor parent in one or more protein bands, which suggested that they in their gene expression to some levels. The present investigation suggested that the application of somaclonal variation, in conjunction with appropriate screening, may provide useful variation to plant breeders for sugarcane improvement.

ABSTRACT

The suitability of the tissue culture technique to screening tomato genotypes for Fe-deficiency tolerance was studied. Six tomato genotypes I.e. UC,W, Hybrid, TM, Roma, Peto 86, and Person were tested. Two different explants, cotyledon and hypocotyl, were used Fe-deficiency tolerance was estimated using stress susceptibility index (S), dry matter, Fe-uptake and Fe-efficiency. Significant differences in all studied traits were observed among genotypes, tissues, and Fe concentrations. Hypocotyl tissue produced more callus than cotyledon. Increasing the Fe concentration in culture increased the amount of callus produced by both tissues. Hypocotyl tissues took up more Fe than cotyledon, but cotyledon was more sensitive to reducing Fe level in culture. Cotyledonary tissues were able to precisely differentiate the Fe-tolerant genotypes. Genotypes W. hybrid and Roma were Fe deficiency tolerant and had the lowest Fe-deficiency stress susceptibility indices (0.67 and 0.84,respectively). Genotype Person was more Fe-efficient.

ABSTRACT

(Thompson Seedless) grown at Orchard of Assiut University and it,s compact bunches, GA

3 (25 or 50 ppm) and CCC (100 or 200 ppm) were sprayed on the whole vine at 3 different application times through seasons 1993 and 1994 to establish an optimum tool to improve flower cluster, meanwhile increasing productivity/vine and improving fruit quality. Although, exogenous GA

3 revealed a slight increase in bud burst percentage. It induced

delaying the peack onset of bud burst occurrence. CCC applications exhibited a considerable increase in bud burst percentage and altered the onset of bud burst peak earlier than treated vines with GA

3 or untreated controls. Nevertheless, bud burst occurrence of this grape cv.

Showed a simple sigmoid curve. In despite of GA3 application resulted in an increase in length

and diameter of shoots at 2nd or 3rd time, caused an insignificant decrease in that at 1st time application. On the other hand CCC spray (100 ppm) at 1st time exhibited an inverse relation to GA

3 applied. Furthermore, an increase in length or framework of grape flower cluster

accompanied GA3 or CCC treatments, but with different proportion among the application times

examined. However, it could be deduced that GA3 treatments were more effective rather than

exogenous CCC in this connection.

ABSTRACT

This study was carried out on Balady, dry date variety; Saidy, semi-dry date variety and one unidentifiable seedling date. Samples from each variety obtained from Kharga Dates Packing Factory, Kharga Oasis, New Valley Governorate, Egypt . Both macro and micro-elements and Vitamins (B1, B2 and C) contents were determined in the above-mentioned date samples and in certain Saidy date products, as well as during maturity stages of Saidy Variety. Among the studied elements, potassium content recorded the highest levels in all varieties. The Rutab stage of Saidy date had lesser K, Na and Fe contents than Balady and Manthour dates but it was intermediate between them in Ca, Mg and Mn; and the highest in copper content. Although, the treated and packed Saidy date products differed in minerals content, the date paste followed by pressed dates (Agwa) recorded the highest iron content. Rather low vitamin content was observed in all studied. Although Saidy variety had the highest vitamins content the latter gradually decreased during its ripening stages .

BULLETIN : Ass. Univ. Bull. Environ. Res., October, 1(2) (1998).

ABSTRACT

The study was carried out on the extracted lipids of four different varieties of plant seeds viz., Sehouwia purpurea; Cassia senna; Cassia italica and Cassia holosericea. The chemical characteristics and lipid classes composition of these lipids were studied. The total lipids content of plant seeds ranged from 6.7 % to 29.87% , depending on the variety. The total lipids extracts were fractionated into neutral lipids, phospholipids and glycolipids by column chromatography. The neutral lipids varied from 95.62% to 96.28%, phospholipids from 2.04% to 2.78% and glycolipids from 1.06% to 1.6%. Thin layer chromatography (TLC) revealed that triglycerides constituted the major fraction of the neutral lipids, for all studied varieties and accounted from 90.78% to 92.70%. TLC showed the presence of seven fractions of phospholipids. The main component of phospholipids was phosphatidyl choline accounted from 36.72 % to 40.62 % of the total phospholipids. The fatty acid composition of total lipids was carried out by gas liquid chromatography (GLC). The plant seed lipids contained high percentage of unsaturated fatty acids consisted mainly of oleic and linoleic acids. Therefore, the studied plant seeds could be used successfully as a source of unsaturated fatty acids, and offer a promising source of oil for nutritional purposes .

ADDRESS : Dept. of Agronomy, Faculty of Agriculture, Assiut University.


ABSTRACT

Eight cultivars of bread wheat were crossed in all possible combinations excluding reciprocals to evaluate such genotypes of some genetic components. General and specific combining abilities were highly significant for all studied characters, except specific combining ability effects for number of spikes/plant which was insignificant. wide range of GCA/SCA ratios was found for most studied traits indicating that additive genetic effects were predominant and played a major role in the inheritance of nearly all traits studied. The results showed that the genotypes Sonora 64 and Sonalika were the earlier in heading and maturity and also gave a highly significant general combining ability effects. Hence they were the best combiners to improve earliness in bread wheat. The results also obtained from this investigation for bread wheat showed that Giza 164 and Giza165 were the best combiners (high additive genetic variance), and high specific combining ability when crossed to Sonora 64 (early), Sonalika and Giza 160, i.e., hybrids of G.165 x Sonalika, G.164 x g.165, G.164 x Sonora 64,G.164 x Sonalika and Sonalika x Sonora 64 produced the best combinations for earliness and yielding ability.

ADDRESS : Dept. of Animal Production, Faculty of Agriculture, Assiut University.

BULLETIN : Assiut, Vet. Med. J. Vol. 30, No 59, October, 1993 .

ABSTRACT

Thirty-five coarse wool Saidi ewes (3-6 yr, 42 Kg) of Upper Egypt were fed, during pregnancy and lactation, 1 to 1.5 Kg/hd daily of apelleted concentrate mixture containing about 2.73 Mcal De/Kg. Considering lambing day as d 0, blood samples were obtained at approximately 90,-75, 43,-21,+4,15,+32 and +55. Serum glucose level tended to be higher (P<.09) in lactating ewes (65.50 mg/dl) than in pregnant ewes (58.46). Serum cholesterol level was higher (P<.01) during pregnancy (118.5 mg/dl) than during lactation (72.8). Within days, cholesterol means increased (P<.05) at d-21 and +55. No significant differences were detected between pregnant and lactating ewes in serum total protein (TP). However, serum TP diminished by as low as 0.676 g/dl between d - 90 and d- 21 (7.15 to 6.48 g/dl) and elevated by 1.27 g/dl between d+4 and d+55 (6.42 to 7.69 g/dl; P>.10). Lactation decreased (P<.03) the level of albumin (3.43 vs 3.83 g/dl) and tended (P<.10) to increase that of globulin (3.43 vs 2.95 g/dl), when compared to pregnancy. Globulin was also higher (P<.05) at d + 32 and d+55 than earlier in lactation. The level. The level of serum urea N during pregnancy slightly (P> .10) exceeded that of lactation (28.5 vs 27.3 mg/dl). No significant differences were detected within days of pregnancy, but the level of serum urea N was the lowest (P<.05) in early lactation (d+4; 23.0 mg/dl) and the highest (P<.05) in late lactation (d + 55; 34.2 mg/dl) and fluctuated in between.

ABSTRACT

Analysis of blood plasma of sixteen pregnant Egyptian Oasis (Farafra) and Chios sheep (8 of each) and their newborn lambs (24 lambs), showed a decrease in plasma immunoglobulin (IgG, 15.24-8.76 and IgM 3.97-3.33 mg/ml), total protein (6.89-6.76 g/dl) and total lipids (200.31-193.19 g/dl) during the late gestation. Colostrum had the highest level of immunoglobulins before suckling, then declined rapidly within the first three days after lambing (IgG, 3.59-1.43 and IgM 4.7-1.5 mg/ml) and total protein (16.91- asma had less immunoglobulins than after suckling. The immunoglobulins increased gradually in the plasma of newlyborn lambs after suckling the colostrum as well as total protein, glucose and total lipids were increased till third day. A negative correlation was observed between consumed colostrum volume and blood constituents in lambs.

ABSTRACT

Pot experiment were conducted with water hyacinth (WH) and K2SO4 applied either alone or in combinations to a coarse textured soil of west Minia to supply the K requirements (24 Kg K2 O4/fed) of wheat and barley. The treatments included supplying 100% of K requirements as WH (T1), 75% WH+25% K2SO4 (T2), 50%WH+50%K2, SO4 (T3), 25%% WH+75% (T4) and 100% K2 SO4 (T5). The recorded yield parameters were: grains and straw yields, weight of 1000 grains, number of grains per spike and NPK concentrations and uptake. The obtained results indicate that WH in general and its combinations with K2SO4 in particular had increased all the above mentioned parameters over T5 (K2SO4 alone) and the increase was more pronounced in nutrients uptake by the two tested crops. Furthermore, the combination treatments (T2, T3, T4) were superior to the single treatments (T1, T5) with T3 as the best. Water hyacinth alone was superior to K2SO4 alone.

ADDRESS : Dept. of Soil and Water, Faculty of Agriculture, Assiut University .


ABSTRACT

This study was undertaken to assess the salination potential of Assiut and Sohag Governorate of Egypt. A large amount of field data was collected, including well surveys, water quality analysis and soil physical and chemical analyses. A GIS was used to develop present spatial data in more suitable ranges and to develop salinity hazards maps. It was found that there is more salinity than sodicity hazards in the two Governorates. In addition, whereas the potential for salination is low in Sohag, it is greater in Assiut. Therefore, use of saline ground water in Assiut should be carefully evaluated so that the problem does not become worse with time. Field studies are needed to develop management plans for irrigation in this Governorate that could look into the combined use of Nile ground water .

ABSTRACT

Analysis of some weather elements such as temperature, relative humidity and wind speed measured in Qena/Egypt has been done. An empirical formula for seasonal averages of these elements at different day times were derived to an acceptable accuracy. The effect of relative humidity and wind speed on the air temperature was studied and led to a definition of specific regions of relative humidity for feeling the air temperature lower than their true values at different seasons. Some valuable recommendations concerning the effect of the measured weather elements on human well-being were given.
