Yearlings and 2-year-olds need protein for maintenance and growth of muscle tissue. Exercise may increase the rate of muscle deposition, thus increasing the protein demand in young, exercising horses 10 to 20 percent above amounts needed for maintenance and normal growth. Proteins are large compounds made of individual amino acids. Several of the amino acids necessary for muscle deposition cannot be synthesized by the horse’s body, and they must be supplied by the diet. As such, the balance of these amino acids or protein quality is an important consideration for exercising horse diets. Fulvic and Humic acids provide essential organic minerals such as selenium, copper, zinc, iron and substances, within the safety limits as prescribed by the Medicines Control Council, that provide ideal bone muscle cartilage hoof and hair growth as well as essential Amino Acids and Enzymes. Don’t overlook our start-up maintenance blend (Renew with Fulvic) which provides excellent growth stimulating effects. Fulvic acids become individually unique molecules or multi-mineral compounds that plants, and animals, absorb, assimilate and utilize to support growth and health. Reference: Recent research shows that humic acid can be used as animal feed thanks to its growth-promoting effect (e.g. Kocabagli et al. 2002).
