Abstract:This study investigated the effects of yeast cultures (YC) on growth performance and nutrient digestion in sheep. This experiment adopted a single factor design, and the groups were randomly divided into 1 control group and 3 test groups according to body weight. The addition of yeast culture in the diet increased the ADG. When YC was added 2%, F/G decreased by 8.42%. With the addition of 1% and 2% YC, the digestibility of NDF increased by 23.06% and 32.14%, and the digestibility of ADF increased by 31.3% and 47.15%, respectively. Adding 1%~2% YC can change the rumen fermentation mode, promote the production of propionic acid, reduce the ratio of feed to weight, and improve the weight gain and feed efficiency of sheep.
