Quality of supplemental protein in a ration for young pigs is an important consideration when formulating the ration. A good ration for young pigs should have an adequate supply of amino acids, and also the amount of amino acids should be in proper proportion to one another and to the other nutrients in the rat ion. Swine rations formulated without animal protein are usually limiting in lysine and methionine, an addition of lysine and methionine may improve the ration. A previous trial (not published) indicated better pig performance with added lysine, methionine, and fat in the ration. Fish flour, an animal protein source, contains a high percentage of lysine, methionine and other amino acids. This product may be a good source of limiting amino acids, other amino acids, and other nutrients. The objectives of the following experiment were: (1) to study the influence of supplemental lysine, alone, on the performance of growing-finishing pigs, ( 2 ) to study the influence of supplemental lysine and methionine in combination on the performance of pigs, (3) to study the effect of the combination of lysine, methionine and fat on the performance of the growing-finishing pigs, (4) to see if fish flour improved the protein quality of a ration, when fish flour constituted a part of the protein supplement in the diet of a growing-finishing pig.
