Amino acids are the building blocks of life

Many tissues of the body are made up of protein. Examples are muscles, internal organs, connective tissue as well as skin, hair and hooves.

Protein is made by the body from 20 different amino acids. 10 of these are essential, which means that the horse cannot produce them on its own and must ingest them with food on a regular basis. The absence of even one of these essential amino acids, such as methionine or lysine for example, can result in impaired protein synthesis by the body.

Growing horses in particular need a protein-optimised feed. Alfalfa is a very valuable source of protein for horses.
