Effects of yeast culture addition on digestion in sheep fed a high concentrate diet


, : Effects of yeast culture addition on digestion in sheep fed a high concentrate diet. Small Ruminant Research 12(1): 27-34

Effects of yeast culture on intake, rumen parameters, digestibility and passage rate were studied in 12 sheep (average BW 59.3 +- 3.5 kg). A high concentrate diet was supplemented with 0 (control), 20 (Y20) or 40 (Y40) g/d of yeast. DMI tended to be higher (P lt 0.06) for Y20 and Y40 diets. Yeast supplements decreased rumen pH (P lt 0.05) and increased total VFA concentration (P lt 0.05) and did not affect the distribution of VFA and acetate to propionate ratio. There were no differences in DM, CP, NDF and ADF digestibility. Ruminal turnover rate and retention time were similar for the diets.
