1. Basic Physical Examination of Horses Chapter #2 Pages 29-45 LACP

2. 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

4. Basic P.E. 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

5. Equine weight measuring tapes

6. Pull the tape so that is it snug and not tight around the horse’s girth.

7. Read the number that meets the “weight arrow” end of your weight tape, this is the animal’s weight in lbs.

9. The height of a horse is measured from the point of the withers to the ground.

10. Measuring height. A, Proper position for the height/weight tape for measuring height. B, Height is read at the highest point of the withers

11. Physical Examination By system Always use the same approach Record your findings Look at “the whole picture”

13. Body Condition Scoring The Ideal Body Condition Score is between 5 and 6-1/2 1. Poor Animal 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 Thin Animal emaciated; slight fat covering over base of spinous processes, transverse processes of lumbar vertebrae feel rounded; spinous processes, ribs, tailhead, tuber coxae (hip joints) and ischia (lower pelvic bones) prominent; withers, shoulders, and neck structure faintly discernable. 3. Thin Fat buildup about halfway on spinous processes; transverse processes cannot be felt; slight fat cover over ribs; spinous processes and ribs easily discernable; tailhead prominent, but individual 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.

14. Body Condition Scoring 4. Moderately Thin Slight ridge along back; faint outline of ribs discernible; tailhead prominence depends on conformation, fat can be felt around it; tuber coxae (hip joints) not discernable; withers, shoulders and neck not obviously thin. 5. Moderate Back is flat (no crease or ridge); ribs not visually distinguishable but easily felt; fat around tailhead beginning to feel spongy; withers appear rounded over spinous processes; shoulders and neck blend smoothly into body. 6. Moderately Fleshy May have slight crease down back; fat over ribs spongy; fat around tailhead soft; fat beginning to be 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 ribs with fat; fat around tailhead soft; fat deposited along withers, behind shoulders,and along neck. 8. Fat Crease down back; difficult to feel ribs, fat around tailhead very soft; fat area along withers filled with fat, area behind shoulder filled with fat, noticeable thickening of neck; fat deposited along inner thighs. 9. Extremely Fat Obvious crease down back; patchy fat appearing over ribs, bulging fat around tailhead; along withers, behind shoulders and along neck, fat along inner thighs may rub together; flank filled with fat.

15. Observation From a Distance Behavior Individual differences Affected by illness/pain Depending on environment, changes throughout the day Eating, drinking Feces, urine

16. Attitude Depressed attitude: Pain Weakness Cerebral dysfunction Abnormal behavior: Pain Cerebral dysfunction

17. Normal values Adults Body temperature (p. 32) normal adult at rest: 99.0-101.5°F —varies by age, breed, environmental temperature Pulse rate/heart rate (p. 33) normal adult at rest: 28-44 bpm —varies by age, fitness level, 2° A-V block Respiratory rate (p. 37) normal adult at rest: 6-12 breaths per minute —varies by age, environmental temperature Gastrointestinal motility (p. 39) normal adult at rest: 1-3 borborygmi per minute Pink gums 6-10 piles of well formed manure per 24 hours

18. 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

19. 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

21. When inserting rectal thermometer, stand facing caudally and maintain contact with the horse

22. Never stand directly in back of the horse’s rear end. Grasp the tail at the base and move it gently to the side

23. Insert the thermometer.

24. A, The thermometer has been inserted and secured with the clip to the tail hairs. B, Thermometer secured to hair coat with the clip.
