PURPOSE:To increase the amino acid content in serum amino acids, and to achieve good result in the breeding of ruminant cattle, by feeding the cattle with a mixture of an inorganic salt such as sodium chloride, a phosphate, a magnesium salt, etc. and a specific amount of amino acid. CONSTITUTION:The titled mixture is prepared by mixing an inorganic salt such as sodium chloride, a phosphate, a magnesium salt, etc. with 0.5-20wt%, based on the inorganic salt, of an amino acid (e.g. lysine, methionine, tryptophan, etc.). The mixture is molded to obtain a solid product. The amino acid may be optically active or racemic, or it may be an acid addition salt such as hydrochloride, acetate, etc. or an alkali salt such as sodium salt, ammonium salt, etc. Good results in the increase of amino acid in serum amino acids and in the breeding of ruminant cattle can be achieved by feeding the cattle with the above mxiture. |
