Indeterminate nodules are the only type found in Caesalpiniodeae and Mimosoideae and the most common type in Papilionoideae (Sprent, 2001; p. 32). As a result of the variety of ways the plant is infected by rhizobia, there are different types of nodules.
Vitamins are organic compounds that are needed in even smaller quantities than minerals by the horse, although no less critical. Vitamins can be divided into two groups, the fat soluble vitamins A, D, E and K and the water soluble C and B-complex vitamins.
Lysine, methionine, and threonine are the most important amino acids that must be provided in equine rations. Diets for young horses need to include sufficient lysine to support growth and development. The protein in mare's milk is a rich source of lysine, as is the soybean meal included in some concentrates.ysine, methionine, and threonine are the most important amino acids that must be provided in equine rations.
