Effect of Pre- and Post-Ruminal Administration of Corn Oil on Ovine Fat

Virginia Polytechnic Institute², Blacksburg

Abstract

Lipid metabolism in adult ruminants differs markedly from that in nonruminants. The hardness of swine fat varies with the character and level of dietary fat. In contrast, ruminant depot fats, such as beef and mutton tallows, are characterized by firmness regardless of diet. The relative consistency of the hardness of ruminant depot fat apparently results from the action of rumen microorganisms in hydrogenating the dietary unsaturated fatty acids (Garton, 1960; Hoflund, Holmberg and Sellman, 1955, 1956a,b; Reiser, 1951; Shorland et al., 1957).

Recent investigations have shown that although ruminant depot fat is somewhat static there are many factors which influence its character, such as nutrition (Edwards et al., 1961) and environment (Marchello, Cramer and Miller, 1967). In the research reported here the effect of pre- and post-ruminal administration of corn oil on fat characteristics of wethers was studied.

Experiment 1. Twelve wether lambs were divided into four outcome groups of three based upon apparent breeding.
