Amino Acids - Feed Ingredient

Amino acids are the fundamental components of proteins and play essential roles in muscle development, enzyme activity, immune function, and overall metabolism in horses. They are classified as essential or non-essential based on whether they must be obtained from the diet or can be synthesized by the horse’s body. Essential amino acids, such as lysine, methionine, and threonine, must be provided in sufficient amounts to support protein synthesis and physiological functions.

In equine nutrition, amino acids are included in feeds and supplements to improve protein quality and ensure balanced nutrient intake. Lysine is considered the first limiting amino acid in horse diets, meaning its deficiency can restrict protein utilization even if total protein intake appears adequate. Methionine, another essential amino acid, is critical for hoof integrity, muscle maintenance, and metabolic processes but is often limited in plant-based protein sources. Proper amino acid balance is particularly important for young, growing horses, performance horses, and those on forage-based diets with lower-quality protein sources.

The following equine feeds, supplements and products contain Amino Acids as an ingredient.
