Abstract

One-hundred-eight wether and ram feeder lambs were used in a factorially designed experiment to study the effect of the levels of energy, levels of sodium chloride, treatments for prevention of enterotoxemia, lines of breeding and sexes on energy metabolism in lambs. Lambs gained more rapidly on the 60% and 90% concentrate energy levels than on the 0% and 30% levels. The proportion of carcass fat, the ratio of fat:protein and the net energy for maintenance and production (NEM + P) of the ration increased as the level of concentrate in the ration increased. Sodium chloride reduced weight gain and energy gain. However, the detrimental effect of sodium chloride decreased as the levels of concentrate in the ration increased. Sodium chloride appeared to increase the NEM+P of the 90% concentrate energy levels. The D line of breeding gained more and had a higher proportion of carcass fat and a greater energy gain than the L line of breeding. The ram lambs gained more than the wethers. The NEM+P of alfalfa hay as fed in the ration decreased as the milo in the ration increased, and the NEM+P of milo in the ration increased as alfalfa hay decreased.
