yeast culture product, performance, limit-fed, grain diet
Eighty weaned steer calves (initial weight 535 Ib) were blocked by weight, allotted within block to 8 pens and limit-fed a high concentrate diet without (CONT) or with Yea-Sacc (YS; 13 g per day). The diet consisted of 69% whole, high moisture corn, 20% ground alfalfa hay, 2% molasses, and 9% supplement (dry matter basis). The diet was fed once daily for an average of 99 days in amounts calculated to result in CONT calf daily gain of 2.25 Ib. As intended, dry matter intakes of calves on the two treatments were identical (13.3 Ib/day). Daily gains averaged 2.40 and 2.32 Ib (P>.20) and feed efficiency 5.55 and 5.73 (P>.20) for CONT and YS, respectively. YS did not improve gain or feed efficiency of growing calves limit-fed a high concentrate diet.
