An experiment was conducted to determine the effects of soyhulls and Biosaf yeast (Saccharomyces cerevisiae) on feedlot performance during the receiving period of newly weaned calves. Two energy sources; corn and soyhulls were fed with or without Biosaf yeast (10g/hd/d). We utilized 154 head of newly weaned steer calves (BW=509 Ib). Energy source had no effect (P>.10) on feedlot performance during the 35d receiving period. Inclusion of Biosaf yeast had no effect on feedlot performance during the 35d receiving period. Consequently, feed cost of gain ($/cwt) was identical for all treatments. Those results indicate soyhulls can replace corn in receiving diets if priced competitively. A longer receiving trial may be needed to detect difference in feedlot performance due to Biosaf yeast inclusion.
