The utilization by growing lambs of a casein-safflower oil supplement treated with formaldehyde.

Abstract

A formaldehyde-treated casein-safflower oil supplement was given at levels of 0, 75, and 150 gjday to lambs receiving 600 gjday of a diet of equal parts chopped lucerne hay and crushed oats. The response of the lambs was studied in terms of food intake and liveweight gain, the chemical composition of the body, the incorporation of linoleic acid into body fat, the digestibility of the diets, and the levels of urea, a-amino nitrogen, and glucose in blood plasma.
