Help your horse reach a healthy weight. The right feed boosts energy, muscle, and coat health.

High-Calorie Nutrition: Underweight horses need feeds packed with calories. Look for high-fat and fiber-rich options to fuel weight gain without overfeeding.
High-Fat Formulas: Fat is a concentrated calorie source. Choose feeds like Manna Pro Cool Calories 100 (99% fat) to add “cool energy” for weight and performance.
Fiber-Rich Blends: Fiber supports steady energy and digestion. Triple Crown Safe Starch and Senior feeds use beet pulp for easy digestion and lasting fuel.
Low Starch/Sugar Options: Horses prone to metabolic issues need low-starch feeds. Triple Crown Safe Starch and Nutrena SafeChoice Original reduce risks while supporting weight.
Senior Horse Formulas: Older horses need easy-to-chew feeds with joint and muscle support. Manna Pro Weight Accelerator and Triple Crown Senior offer Omega-3s and probiotics.
