Monitoring WeightWhy is it important to monitor weight?
Prevent too much weight gain or lossSudden changes can indicate health problems
Too heavy - risk of:laminitis, insulin resistance, reproductive problems, exercise intolerance, heat exhaustion
Too thin – risk of:compromised immune system, muscle wasting, exercise intolerance, parasite problems, cold intolerance, malnutrition

Henneke Body Condition Scoring System
• Developed by Dr. Don Henneke, University of Texas, 1983• Article published in the Equine Veterinary Journal
• Scores 1-9• 1-2 = emaciated• 3-4 = thin• 5–6 = range of ideal scores• 7 = overweight• 8-9 = obese
• Ideal body condition depends on:• Breed• Discipline• Age• Climate
-
What is ideal body condition?• Often subjective, “ideal” may vary by discipline
• Example: endurance horses are usually leaner than show-fit halter horses.
The horse's physical condition is rated on visual appraisal and palpation (feel) of six conformation points:
1. the amount of flesh or fat covering the neck2. the withers3. down the crease of the back4. at the tailhead5. ribs6. behind the shoulder at the girth

-
BCS = 1 (Poor)
• Extremely Emaciated
• Bones Project Prominently
Spine, Ribs, Hips, Withers
• No Fat Anywhere
• Intense care needed for re-feeding

BCS = 2 (Very Thin)
• Emaciated
• Bones ProminentSpine, Ribs, Tailhead, Hips

• Not Obviously Thin
MUST BE a minimum of a “4” to
participate in Ohio 4-H Horse Program
-
BCS = 5
(Moderate: Ideal Weight)

• Withers rounded / Shoulders Blend
-
BCS = 6
(Moderately Fleshy)
• Slight Crease down Back
• Spongy fat over ribs
• Soft fat around Tailhead
• Fat around withers, shoulders
-
BCS = 7 (Fleshy)

Neck
-

Estimating A Horse’s Weight
Weight Tape: Very useful to monitor changes (caution using tape
with Draft breeds or Minis)
Calculation:
2yr & older: (HG x HG x BL) / 330
Yearling: (HG x HG x BL) / 301
Weanling: (HG x HG x BL) / 280 HG= Heart Girth
BL=Body Length
-
Measuring HG and BLNotes:
• BL (Body length)
measurement is not
quite the same as
measuring for a
blanket!
• HG (heart girth)
measurement taken
about 4 inches
behind shoulder.
-
Another Tool…
Body Condition Index (BCI)
More objective than BCS, which is very subjective
Similar to Body Mass Index (BMI) in humans
Useful when:
Multiple people are monitoring the same horse over time
Additional measure of change in condition

Stand on level surface
Relaxed, square stance
Measure (cm):
Height
Neck Circumference
Heart Girth
Belly Girth (mid-back)

Help & Advice
Weight Management Tools
Does not account for horse’s lengthDOES allow monitoring change
Equation:
BCI = [HG0.5 + (BG+NC1.2)/H1.05]2.2

What if…???…my horse is too thin!!!
Consult with equine nutritionist and veterinarianRule out health problems
Increase calories (fat)
Increase forage
Caloric intake and grain need to be increased SLOWLY and CAREFULLY
Too much too fast = digestive upsetrisk of cardiac problems in emaciated horses
Increase fat content of diet
Ease workload, if applicable• Every 1 unit increase in BCS, requires
approximately 50# BW gain.
• Feed an additional 4.5# of feed
-
What if…???…my horse is too fat!!!
Consult with equine nutritionist and veterinarianTest for insulin resistance, if necessary
Rule out other metabolic issues
Decrease caloric intake Soak hay
Reduce grain, provide GRO ‘N WIN®
Limit pasture – grazing muzzle if needed
Increase exercise slowly as tolerated
Increase turnout
Do NOT starve horse!
-
What if…???…I don’t know if my horse is too thin or too fat or just right!!!
Estimate weightWeight tape or calculation
Body condition
Is this “ideal” for the horse’s size/breed/discipline?
What is the horse’s regular diet?Do adjustments need to be made?
