Effect of Acetate and Propionate on the Utilization of Energy by Growing-Fattening Lambs
Growing-fattening lambs fed a basal ration of pelleted alfalfa hay showed no response in either rate of gain in body weight or feed required per unit gain when propionate or acetate was incorporated in the feed. The addition of corn to the basal ration resulted in a significantly faster rate of gain...

Zusammenfassung: | Growing-fattening lambs fed a basal ration of pelleted alfalfa hay showed no response in either rate of gain in body weight or feed required per unit gain when propionate or acetate was incorporated in the feed. The addition of corn to the basal ration resulted in a significantly faster rate of gain. Estimates of the composition of gains were obtained by slaughter and chemical analysis of 4 lambs at the beginning, and 2 lambs from each treatment group at the end of the trial. The gains of the lambs fed propionate, acetate or corn were considerably higher in fat than those of controls. On an energetic basis, these groups converted digestible energy to body gain with considerably greater efficiency than the control group. No difference in efficiency was observed among supplements. |
