Weight Management in Horses: Welfare and Health Balance

Equine obesity is a welfare and health concern associated with laminitis risk, and safe, effective weight management requires management changes rather than starvation.

Key Facts

Equine obesity is increasingly common due to improved nutrition and reduced workload
Body condition score above 7/9 significantly increases laminitis risk in at-risk breeds
Easy-keeper breeds including Natives, Warmbloods, and many cobs gain weight on minimal forage
Grazing muzzles reduce grass intake by 75-80% while allowing some grazing behavior
Hay nets with small holes extend eating time and reduce intake without withholding forage
Equine metabolic syndrome (EMS) is associated with obesity and significantly increases laminitis risk
Safe weight loss rate is approximately 0.5-1% body weight per week

Welfare Considerations

Obesity in horses causes genuine health harm - increased laminitis risk, joint loading, and metabolic dysfunction. However, the welfare cost of inappropriate management of obesity must be considered. Horses deprived of sufficient forage develop gastric ulcers, stereotypies, and behavioral problems. Safe weight management restricts calorie intake while maintaining forage availability through extended eating time strategies. Horses should lose weight slowly through management changes - never through acute forage deprivation.

What You Can Do

Body condition score your horse monthly using a validated scoring system
Implement a grazing muzzle for overweight horses during high-risk spring and autumn grass periods
Use small-hole hay nets to extend eating time and reduce calorie intake without withholding forage
Increase exercise gradually as part of a safe weight management program
Test for EMS in overweight horses that have had unexplained laminitis episodes
