What kind of information / records

to keep in management of sheep? Animal records

breeding record

production record health and medication

Farm operations

pasture management activities

feeds

sales and animal disposals

ETC...

When do we gather the data or

informationThe best time is... in that particular stage of

the life cycle of an animal where the

characteristic is expressed to the fullest.

For example, you want to measure a pigs weaning weight at 30 days ofage. In this case, to standardize would mean to measure the weight of all pigs at

this particular age. But since it is not always possible to weigh each pig at exactly

30 days of age, correction factors have been devised to adjust the weights to thisstandard basis:

actual weight

Adjusted weight = ------------------------ (30)

actual age


13/15

Sheep Reproduction and Production Performance:

Lambing Rate (%) = No. of ewes lambing number ofewes exposed to ram x 100

Weaning Rate (%) = No. of lambs weaned number ofewes exposed to ram x 100

Prolificacy (%) = Number of lambs born number ofewes lambing x 100

Fertility Rate (%) = Lambing rate x Prolificacy Lambinginterval

Lambing interval (days) =Average between 2 consecutivelambing

Lambing per year= 365 days lambing interval

Annual Productivity Rate = Litter Size x Survival Rate

Lambing Interval (years)


14/15

The timing of the management practice is as important

as the practice itself

support facilities and appropriate equipment

Certain basic records must be keptto monitor flock

performance and analyzed and interpretedAid in making decisions

No single system of production is right for everyoneContributory factors include available facilities, labor and

management resources, genetics, pasture and feed resources,and the operation's marketing program

Critical important areas must be considered for every flock

include internal parasite control, foot-rot control, and predator

control.
