What is the primary use of alfalfa in horse nutrition?

Alfalfa is primarily used in horse nutrition as a source of complete protein. This legume forage boasts a high protein content, making it an excellent feed choice for horses, particularly for those in need of additional protein, such as young, growing horses, lactating mares, or performance horses engaged in intense physical activity. The quality of protein in alfalfa is considered superior because it contains all essential amino acids required for growth and maintenance.

While some of the other options do present additional roles for alfalfa, such as providing minerals and potentially being used in bedding, these are secondary to its role as a nutrient-dense forage that supports the overall health and performance of horses. Alfalfa's rich nutrient profile helps in muscle development, recovery, and overall vitality, reinforcing its primary purpose in equine diets.
