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.
Minerals are inorganic nutrients that are needed in relatively small quantities by the horse. The essential major minerals are calcium, phosphorus, magnesium, sodium, chloride, potassium and sulfur. The essential trace minerals needed are iron, zinc, copper, selenium, manganese, iodine, and cobalt.
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.
