Some Effects of Feeding Various Filled Milks to Dairy Calves. I. Physical Condition and Weight Gains, with Special Reference to Low-Fat Rations

Abstract

Corn oil filled milk adversely affected physical condition, weight gains, and feed utilization of calves. Animals fed lard and butter oil, prepared from oxidized butter, exhibited symptoms of muscular involvement as did corn oil filled milk calves. Supplementation of the corn oil and lard diets with tocopherol prevented muscular involvement, but did not improve weight gains of calves fed corn oil. Data presented suggest that corn oil depresses calve growth. Diets containing as low as 0. 10-0.15% butterfat were not detrimental to growth and physical condition under the experimental conditions.
