Why Horses Lose Weight
Pecking Order
Within a herd of horses, even a small herd such as we keep on our own properties, there are bullies and underdogs. Often the underdogs are bullied away from bale feeders or the best grazing. This can lead to weight loss simply because the horse that is being bullied can’t get enough to eat in addition to being stressed.
Disease and Illness
A number of health problems can cause weight loss. Ulcers are common, especially in performance horses. EPM, HYPP, Cushings, EGUS or Gastric Ulcers, mineral or vitamin deficiencies and diseases such as cancer or kidney and liver disorders can cause appetite and digestive problems leading to weight loss.
What to Do Next
The first step to discovering the cause of the weight loss is to determine exactly how much the horse is eating. This might mean separating it from the other horses for a while. Deworming medication should be administered and don’t underestimate the importance of water in your horse’s diet. Feeding For Weight gain offers some tips for what to feed your lean horse. If after increasing the feed and being sure the horse is dewormed, there is no improvement you may need to consult a veterinarian about checking the horse’s teeth. If after dental work is done, there is still no improvement the veterinarian can take blood samples to ensure there is no condition or disease causing the weight loss.
