Influence of High Levels of Plant and Animal Fats in Calf Starters on Growth, Feed Consumption, and Palatability

Dairy Department, University of Georgia, Athens¹

ABSTRACT

In a growth experiment with seven calves per starter, the addition of 10% brown grease, 10% hydrogenated cottonseed oil, or 5% of each to calf starters markedly reduced consumption and weight gain. The addition of 10% of each of the fats further reduced weight gains and starter consumption. The simple and partial correlations between starter consumption and weight gains were 0.84 and 0.85, which indicates that a major portion of the reduction in growth was associated with reduced starter intake. In a cafeteria study, each of nine calves significantly preferred the control starter. However, one calf demonstrated a similar decisive preference for the starter with 10% added brown grease. In another cafeteria study with 11 calves, 1% brown grease did not significantly affect palatability of a calf starter.
