Amino Acids

You may remember from high school biology, amino acids are the building blocks of protein.  Horses, like humans, require protein to build body proteins for the function of vital organs, muscles, skin, hair, hooves, bones, connective tissue, immune function and red blood cells.

There are 10 amino acids that horses cannot produce themselves, these are called essential amino acids.  Check your ingredient label on your chosen grain to see what essential amino acids are included in the feed.  Again, an analysis of your hay and pasture will tell you the level of amino acids are present.  The 10 essential amino acids will provide quality protein when used together and in proportion.

Essential Amino Acids

  • Lysine

  • Methionine

  • Threonine

  • Leucine

  • Arginine

  • Isoleucine

  • Histidine

  • Phenylananine

  • Valine

  • Tryptophan

Lysine and methionine are two amino acids that are often low in pasture and grass hay, therefore adding alfalfa will help to balance the requirement.  From my research, only lysine had a designated requirement, which is 27 grams per day for a 1,100 pound horse. 


Horsetech offers Nutramino, an amino acid supplement containing lysine, methionine, and threonine.
