Abstract
Four experiments involving 224 pigs were conducted to study the baby pig's ability to utilize butter, coconut oil, corn oil, methyl esters of the fatty acids of corn oil, lard and soybean oil, and partially hydrolyzed animal and vegetable fat when added at levels up to 20% of the diet. Apparent digestibility of fat increased significantly between 10 and 28 days on experiment. Addition of fat to the diet failed to improve consistently either gain or feed efficiency. Among the fat sources, coconut oil and butter were utilized more efficiently; lard, corn oil and soybean oil were intermediate. These experiments illustrate that the young pig cannot efficiently utilize the fat sources tested and suggest that protein source may influence the efficiency of fat utilization. Copyright © 1970.
