Basic Physical Examination of Horses Chapter #5 LACP
Examination of Horses• The history and physical examination are the most important
part of the database and serve as the starting point for identifying the patient’s problems
History• History• Coach the client- • Individual –food and water source, feeding practices• Management of the entire group • Environmental stresses- pasture management, new animals• Prior treatments- other veterinarians, or self medications/treatments• Do not pass judgment
Physical Examination
• Physical examination• Baseline• Potential problems
• Insurance examination• Required
• Prepurchase examination• Used in the sale of horses• It is not a guarantee of horses future performance
Physical examination
• There are several types of physical examinations for equines• Insurance examination is required by the
insurance company before a horse can receive insurance coverage• Prepurchase examination, conducted before
completing the sale of an animal, the veterinarian performing the examination is presumed to be working in the buyer’s best interest
Basic Physical Exam
Visual Observation• Observe the animal from a distance • Gait• Posture• Hair coat• Behavior• Breathing pattern • Respiratory noises• Body swellings• Skin wound• Etc.
Observation From a Distance
Behavior• Individual differences• Affected by illness/pain• Depending on environment, changes
throughout the day• Eating, drinking• Feces, urine
Body Condition Scoring The Ideal Body Condition Score is between 5 and 6-1/21. PoorAnimal extremely emaciated; spinous processes, ribs, tailhead,tuber coxae (hip joints), and ischia (lower pelvic bones)projecting prominently; bone structure of withers, shoulders,and neck easily noticeable; no fatty tissue can be felt.2. Very ThinAnimal emaciated; slight fat covering over base of spinousprocesses, transverse processes of lumbar vertebrae feelrounded; spinous processes, ribs, tailhead, tuber coxae (hipjoints) and ischia (lower pelvic bones) prominent; withers,shoulders, and neck structure faintly discernable.3. ThinFat buildup about halfway on spinous processes; transverseprocesses cannot be felt; slight fat cover over ribs; spinousprocesses and ribs easily discernable; tailhead prominent, butindividual vertebrae cannot be identified visually; tuber coxae(hip joints), appear rounded but easily discernable;tuber ischia (lower pelvic bones) not distinguishable; withers,shoulders and neck accentuated.
Body Condition Scoring 4. Moderately Thin Slight ridge along back; faint outline of ribs discernible; tailhead prominence depends onconformation, fat can be felt around it; tuber coxae (hip joints) not discernable; withers, shouldersand neck not obviously thin. 5. Moderate Back is flat (no crease or ridge); ribs not visually distinguishable but easily felt; fat around tailheadbeginning to feel spongy; withers appear rounded over spinous processes; shoulders and neckblend smoothly into body. 6. Moderately Fleshy May have slight crease down back; fat over ribs spongy; fat around tailhead soft; fat beginning tobe deposited along the side of withers, behind shoulders, and along sides of neck. 7. Fleshy May have slight crease down back; individual ribs can be felt, but noticeable filling between ribswith fat; fat around tailhead soft; fat deposited along withers, behind shoulders,and along neck. 8. FatCrease down back; difficult to feel ribs, fat around tailhead very soft; fat area along withers filledwith fat, area behind shoulder filled with fat, noticeable thickening of neck; fat deposited alonginner thighs. 9. Extremely Fat Obvious crease down back; patchy fat appearing over ribs, bulging fat around tailhead; alongwithers, behind shoulders and along neck, fat along inner thighs may rub together; flank filledwith fat.Courtesy of Purina Mills
Attitude
Depressed attitude:• Pain• Weakness• Cerebral dysfunction
Abnormal behavior:• Pain• Cerebral dysfunction
• The basic physical examination usually includes temperature/pulse/respiration (TPR) heart/lung auscultation, abdominal auscultation, hydratation status, examination of mucous membranes, and height/weight measurement
Normal values- Adults (p. 149)Body temperature- normal adult at rest: 99.0-101.5°F —varies by age, breed, environmental temperature Pulse rate/heart rate- normal adult at rest: 28-44 bpm —varies by age, fitness level, 2° A-V blockRespiratory rate- normal adult at rest: 6-12 breaths per minute —varies by age, environmental temperature
Gastrointestinal motility (p. 130) normal adult at rest: 1-3 borborygmi per minute
Borborygmus- rumbling or gurgling noises produced by movement of gas in the alimentary canal and audible at a distance
Pink gums6-10 piles of well formed manure per 24 hours
Normal Neonate
• Temperature 99-102F• HR 80-120• RR 20-40• Pink gums• Nursing 4-6 times per hour• Fecal output 2-4 piles per day, pasty
Equine weight measuring
tapes
Pull the tape so that is it snug and not tight around the horse’s girth.
Read the number that meets the “weight arrow” end of your weight tape, this is the animal’s weight in lbs.
• Page 487 CVTV
The height of a horse is measured from the point of the withers to the ground.
Measuring height. A, Proper position for the height/weight tape for
measuring height. B, Height is read at the highest point of the withers
Physical Examination
• By system• Always use the same approach• Record your findings• Look at “the whole picture”
Body temperature
• Temperature is almost always taken rectally using a standard mercury thermometer or a digital thermometer for large animals
Look Familiar?
99-101.5
When inserting rectal thermometer, stand facing
caudally and maintain contact with the horse
Never stand directly in back of the horse’s rear end.
Grasp the tail at the base and move it gently to the side
