We get a LOT of questions and comments from customers about feeding alfalfa to horses. There are many myths circulated about alfalfa, which is unfortunate, because it can be an excellent horse feed. Alfalfa is a legume hay that is generally low in sugars, has no fructans (a type of sugar), is high in calcium and quality protein, and because of its very deep root systems – up to 49 feet into the ground – alfalfa plants are able to access nutrients deep in the soil that other plants cannot. Alfalfa can be a big help to horses who suffer from gastric ulcers, it provides abundant minerals and amino acids, and horses love to eat it! Many horse people are afraid to feed alfalfa, so we’d like to present some information here on alfalfa and protein to help people to make educated choices about both.
Protein is made up of essential and non-essential amino acids. The horse’s body can synthesize some amino acids on its own, so those ones are called “non-essential” because the horse does not need to consume them in his feed. Essential amino acids must come from the horse’s diet. These are: arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Amino acids work together to form complete proteins, so if one is missing or in short supply, this limits the amount of protein available to the horse (more…)
