Abstract

The purpose of this experiment was to investigate the effects of different supplemental levels of beer yeast on cecal microflora and nutrient digestibility of growing Rex rabbits. A total of 120 healthy white Rex rabbits (half male and female half) with a similar body weight at 30 days of age were divided into 4 groups with 30 replicates per group and 1 rabbit per replicate. Rex rabbits in the control group was fed a basal diet, and those in test groups Ⅰ, Ⅱ and Ⅲ were fed the experimental diets that replaced the soybean meal of basal diets with 5, 10, 15 kg/t beer yeast, respectively. The pre-feeding period lasted for 10 days, and the experimental period lasted for 60 days. The results showed as follows:1) on 60, 80 and 100 days of age, the operational taxonomic units (OUT) number of cecal microflora of all test groups was significantly higher than that of the control group (P<0.05). On 80 days of age, the Ace index of all test groups was significantly higher than that of the control group (P<0.05), the Chao1 index of test groups Ⅰ and Ⅲ was significantly higher than that of the control group (P<0.05); on 100 days of age, the Shannon index of test group Ⅱ was significantly higher than that of the control group (P<0.05). 2) The digestibilities of dry matter, total energy, phosphorus, crude protein and neutral detergent fiber were the highest, and significantly higher than those of the control group (P<0.05). In conclusion, beer yeast can enrich the cecal microbial population and contributes to the establishment of the cecal microflora homeostasis, and improves the nutrient digestibility of Rex rabbits.
