What Causes Weight Loss in Horses?
Weight loss in horses can happen for lots of reasons: from high metabolism and aging, to dental issues or demanding training schedules. Poor absorption is another factor, which is why pairing weight support with digestive and gut supplements can make a big difference. When calories fall short, horses lose condition, their coats dull, and toplines soften.
Corro Team Rider Megan Kepferle, Eventing shares that eventers burn through calories fast, making horse weight gain supplements key for recovery.
Rider Nick Haness, Hunter/Jumper adds that picky eaters under show stress often drop weight, which is why high-calorie horse feed makes such a difference.
How Weight Gain Supplements Can Help
Research backs up what riders already see in the barn:
A study in the Equine Veterinary Journal (1999) found that adding vegetable oils to horses’ diets improved body condition and maintained coat quality without making horses excitable.
More recently, a trial published in 2023 showed that oils like camelina, flaxseed, and canola supported healthier skin and glossier coats in horses.
These findings show how the right weight gain supplements that are rich in fat and balanced nutrients can safely support condition, shine, and steady weight without turning up the heat.
Choosing the Right Weight Gainer
Picking the right weight gainer for horses depends on your horse’s lifestyle. Performance athletes often need calorie-rich oils, while seniors may benefit from fat-protein blends to hold their topline. Horses in steady work might do best with balanced formulas that keep them shining and in condition. Here’s a quick guide:
- Performance horses: Calorie-dense oils for weight and shine
- Senior horses: Fat-protein blends for topline and bloom
- Everyday keepers: Balanced formulas for steady weight maintenance
