Farm Flock Lamb Creep Feeding Tests¹

Utah Agricultural Experiment Station, Logan

Abstract

Four creep feeding trials were conducted to determine the effect of certain rations and feeding practices upon lamb gains and economy of farm flock lamb fattening enterprises.

Chlortetracycline had no effect upon either feed consumption or lamb gains when added to the creep ration at levels of 10 and 20 mg. per pound of creep concentrate.

A complex ration did not give increased lamb gains over a simple formula ration; however, rolled barley alone did not produce gains equal to either of the other two rations. Lambs receiving only rolled barley experienced difficulty in attaining and maintaining high levels of consumption. Creep fed lambs from ewes fed only alfalfa gained equally as fast as lambs from ewes fed one pound rolled barley in addition to alfalfa. Ewes fed only alfalfa consumed 0.9 lb. more alfalfa per day and lost 9.0 lb. more body weight than ewes receiving grain.
