When you plan a feeding program for your young horses, several factors are very important:
- body changes involved in growth,
- nutrient requirements of that particular class of horse,
- the feed’s nutrient content,
- anatomical limitations of young horses’ digestive system, for instance, you cannot feed young horses low-energy, bulky feeds because their digestive tracts are not large enough. Instead, young horses need concentrated sources of energy, protein, vitamins and minerals to meet their nutritive needs.
