Supplements to Peanut Oil Meal Protein for Growing Fattening Swine

Abstract

Two trials were conducted to determine whether supplementing peanut oil meal with lysine, lysine and methionine or natural sources of these amino acids, namely, blood meal and fish products, would make this protein feed a satisfactory supplement to corn for growing-fattening swine. These supplements, when added to peanut oil meal-corn rations, produced highly significant improvements in rate of gain and muscle development. The data show that proper levels or balance of these amino acids is important. It appears that lysine may have a specific effect on loin area. The growth patterns may possibly account for differences in loin areas. The growth patterns also show the effect of these treatments on pigs at different weights. Copyright © . .
