啤酒酵母对生长獭兔盲肠微生物及营养物质消化率的影响
Effects of Beer Yeast on Cecal Microflora and Nutrient Digestibility of Growing Rex Rabbits
摘要
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 experi-mental period lasted for 60 days. The results showed as follows: 1) on 60, 80 and 100 days of age, the opera-tional 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 groupⅡwas 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 es-tablishment of the cecal microflora homeostasis, and improves the nutrient digestibility of Rex rabbits.[ Chinese Journal of Animal Nutrition, 2019, 31(3) :1352-1359]关键词
