10 Tips for Weight Reduction in the Overweight Horse
As a horse owner, you play an important role in controlling your equine companion’s weight.
Sound nutrition management, a regular exercise program and veterinary care are key to keeping
your horse fit and healthy. Maintaining the ideal weight is not always easy, however.
When implementing a weight loss program for the overweight horse, it’s important to do it
gradually and under the supervision of an equine veterinarian. Follow these guidelines from the
American Association of Equine Practitioners (AAEP) to get you started:
1. Be patient. Weight reduction should be a slow, steady process so not to stress the horse or
create metabolic upsets.
2. Make changes in both the type and amount of feed gradually. Reduce rations by no more
than 10% over a 7- to 10-day period.
3. Track your horse’s progress by using a weight tape. When the horse’s weight plateaus,
gradually cut back its ration again.
4. Step up the horse’s exercise regimen. Gradually build time and intensity as the horse’s
5. Provide plenty of clean, fresh water so the horse’s digestive and other systems function as
efficiently as possible and rid the body of metabolic and other wastes.
6. Select feeds that provide plenty of high quality fiber but are low in total energy. Measure
feeds by weight rather than by volume to determine appropriate rations.
7. Select feeds that are lower in fat since fat is an energy-dense nutrient source.
8. Switch or reduce the amount of alfalfa hay feed. Replace with a mature grass or oat hay to
reduce caloric intake.
9. Feed separate from other horses so the overweight horse doesn’t have a chance to eat his
portion and his neighbor’s too. In extreme cases of obesity, caloric intake may also need to
be controlled by limiting pasture intake.
10. Balance the horse’s diet based on age and activity level. Make sure the horse’s vitamin,
mineral and protein requirements continue to be met.
Once your horse has reached its ideal body condition, maintaining the proper weight is a
gentle balancing act. You will probably need to readjust your horse’s ration to stabilize its
weight. Exercise will continue to be a key component in keeping the horse fit. Because obesity
can affect a horse’s health, communicate regularly with your veterinarian. Schedule regular
check-ups, especially during the weight reduction process.
