PROBLEM TO BE SOLVED: To produce a feed composition improved in the rumen by-passability of proteins and amino acids and low in solubility in water by coating a mixture containing proteins or amino acids with a protecting substance high in a nutritive value and high in digestibility and absorbability in the abomasum by a simple and inexpensive coating means. SOLUTION: This method for producing a feed composition comprises adding 1-150 pts.wt. of proteins or amino acids to 100 pts.wt. of fatty acids, subsequently dropping and reacting the mixture into an aqueous dispersion comprising 300-1,000 pts.wt. of water and 3-60 pts.wt. of a metal compound, or dropping and reacting an aqueous solution comprising 100-400 pts.wt. of water and 5-40 pts.wt. of an alkali hydroxide into the mixture, and further adding and reacting an aqueous solution comprising 100-300 pts.wt. of water and 5-70 pts.wt. of a metal halide. |
