(57) [Summary] [Structure] When feeding livestock for meat, for example pigs, the average number of amino acid residues is 10 or less, especially 2 to normal feed. The oligopeptides of 3 are mixed at about 0.1% and given. The oligopeptide is preferably obtained by enzymatic partial hydrolysis of soybean protein. Before shipment of adult pigs 5-1 The method is applied for 0 weeks, but can be applied to piglets. [Effect] By the above-mentioned feed administration, a remarkable weight-increasing effect or a feed-reducing rate reducing effect can be obtained, but the quality of meat such as pork obtained thereby does not deteriorate, and the fat content remarkably decreases. And the quality is rather improved. Moreover, there is no problem in terms of safety. |
