Interactive effects of yeast and yeast cell wall material on feedlot performance during the receiving period of stressed beef cattle [abstract]. 2010 American Society of Animal Science Meeting, July 11-15, 2010, Denver, CO. Journal of Animal Science. 88(E-Supplement 2):W383.Interpretive Summary:
                                Technical Abstract: The objective of this experiment was to determine the potential effects of live yeast and yeast cell wall supplements on performance and health of cattle during the receiving period. Newly-weaned crossbred steers (n = 184; 9 pens/treatment; BW = 203 +/- SEM kg) were blocked by BW and randomly assigned to pen (4 pens/block; 5 or 6 hd/pen). Pens within a block were randomly assigned to one of four treatments: 1) control (CON; diet containing no yeast additives), 2) live yeast (LY; CON diet with the addition of 5 g/hd/d live yeast product), 3) yeast cell wall (YCW; CONT diet with the addition of 5 g/hd/d yeast cell wall product), 4) live yeast + yeast cell wall (LY+YCW; CONT diet with the addition of 5 g/hd/d LY and 5 g/hd/d YCW). A randomized complete block design was used; data was analyzed either as 4 separate treatments or treatments 2 and 3 were combined to analyze the overall effect of yeast product inclusion level (0, 5, and 10 g inclusion). Daily DMI was recorded and individual BW were collected every 14 d for the 56-d feeding period. When analyzed as four separate treatments, interim and cumulative BW, ADG, and G:F were similar (P > 0.10) among all treatments. Cumulative DMI was increased (P < 0.05) for the LY, YCW, and LY+YCW compared to CON (5.47, 6.02, 5.96, and 5.89 kg/d, respectively). DMI differed for d 0 to 28 (5.03, 5.59, and 5.42 kg for 0, 5, or 10 g LY or YCW/day respectively; P = 0.02, quadratic), d 0 to 42 (5.17, 5.75, and 5.62 kg/d; P = 0.02), and cumulative (5.46, 5.99, and 5.88 kg/d; P = 0.03). Steer morbidity and mortality was not affected by LY or YCW supplementation (P > 0.10). Collectively, these data indicated that the use of LY or YCW additives increase total feed consumed by the steers during the first 56 d of the feeding period.
