Stabilized White Grease and Corn Oil in the Diet of Baby Pigs¹

University of Wisconsin³, Madison

Abstract

Forty baby pigs were used in an experiment to determine the value of added grease and corn oil in a baby pig ration high in available nutrients. Pigs fed grease showed no advantage in weight gain, feed efficiency or energy conversion over controls. Pigs fed corn oil gained more slowly and less efficiently than the controls and their body fat had a higher saponification number and iodine number. Higher blood fat, fat content of the shoulder and lower specific gravity of carcass were observed in all groups of fat-fed pigs.

In digestion trials the inclusion of 10% and 20% grease in the rations of 8-week-old pigs increased the apparent digestibility of ether extract and protein.
