The role of protein in a horse’s diet is crucial for various bodily functions, including muscle growth and repair, especially for young, growing horses. While carbohydrates and fats are the primary energy sources, protein becomes essential when energy intake is insufficient or when the horse’s protein needs are elevated due to growth, pregnancy, or lactation.
Why is Protein Important for Horses?
Proteins are composed of amino acids, which are vital for building and repairing tissues. Horses require protein for:
- Growth: Immature horses need protein to develop muscles and other body parts.
- Maintenance: All horses need a small amount of protein for the daily repair of muscles, internal organs, and other body tissues.
- Reproduction: Additional protein is needed in the feed of mares during pregnancy and lactation.
What are the Essential Amino Acids for Horses?
Monogastric animals, like horses, require specific amounts of essential amino acids daily. These include arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. High-quality protein sources, such as soybean meal, contain high concentrations of these essential amino acids in the proper balance for their full utilization.
How Much Protein Does a Horse Need?
The specific nutrient requirements of horses are not fully understood. However, good quality grass-legume pastures can supply adequate nutrients to maintain an adult horse at light work or mares during pregnancy. Lush, early spring pasture is very high in protein and may need to be supplemented with a high-energy source, such as grain, for horses performing medium to heavy work. Late fall- and winter-pasture forage is low in protein and may require protein supplementation. Weanling foals require three pounds of feed per hundred pounds of live weight per day; as they approach maturity, this requirement drops to one pound of feed per hundred pounds of live weight daily.
What are Good Sources of Protein for Horses?
- Legume Hays: High-quality legume hays, such as early bloom alfalfa, are preferred for horses, especially those that are growing or lactating.
- Pasture: Good quality grass-legume pastures can supply adequate nutrients.
- Concentrates: Grains such as oats, corn, barley, wheat, and milo can be used to supplement protein intake.
- Complete Horse Rations: These rations are tailored to the total needs of specific animals according to their particular function at a given time, such as growth, pregnancy, lactation, or maintenance.
- Soybean Meal: High-quality protein source containing high concentrations of essential amino acids.

What happens if a horse doesn’t get enough protein?
Protein deficiency in horses can lead to poor muscle development, reduced growth rates, weakened immune systems, and decreased performance. It is particularly detrimental to young, growing horses and pregnant or lactating mares, as their protein requirements are higher.
Can horses get too much protein?
While protein is essential, excessive protein intake can also be detrimental. When protein intake exceeds the horse’s needs, the surplus is stored as body fat, which can be utilized later as a source of energy if less food becomes available.
How do I know if my horse is getting enough protein?
Signs of adequate protein intake include healthy muscle development, good coat condition, and overall vitality. If you are concerned about your horse’s protein intake, consult with a veterinarian or equine nutritionist to assess their diet and make appropriate adjustments.
In summary, protein plays a vital role in a horse’s diet, supporting muscle growth, tissue repair, and overall health. Ensuring an adequate intake of high-quality protein is essential, particularly for young, growing horses and those with increased protein demands due to pregnancy or lactation.
