PROBLEM TO BE SOLVED: To obtain the subject regulator good in palatability without deteriorating the feed intake by prepartal dam cow by encapsulating an active ingredient selected from an inorganic chloride, an inorganic sulfate and a hydrochloride or a sulfate of an amino compound. SOLUTION: This regulator is obtained by encapsulating at least one selected from (A) an inorganic chloride, (B) an inorganic sulfate, (C) a hydrochloride of an amino compound and (D) a sulfate of the amino compound as an active ingredient. Ammonium chloride, magnesium chloride, etc., are cited as the ingredient A. Calcium sulfate, magnesium sulfate, etc., are cited as the ingredient B. Not only an amino acid but also a protein having amino groups and a peptide which is its hydrolyzate are included in the amino compound in the ingredients C and D. Thereby, the hydrochloride and sulfate of the amino compound, an acid precipitated fraction of a soybean protein by hydrochloric acid or sulfuric acid or an acid precipitated fraction, etc., of a peptide prepared by hydrolyzing the protein by the hydrochloric acid or sulfuric acid, etc., are cited as the ingredients C and D. |
