益生菌对蛋鸡早期生长、饲粮养分利用和 肠道菌群的影响
Effects of Probiotics on Growth, Diet Nutrient Utilization and Intestinal Microflora in Early Life of Layer Chickens
摘要
Abstract
This experiment was conducted to investigate the effects of dietary probiotics on growth, diet nutri-ent utilization and intestinal microflora in early life of layer chickens. Five hundred and forty 1-day-old male chicks were randomly divided into 3 groups with 6 replicates per group and 30 chicks per replicate. The birds in control group were fed a basal diet. The birds in antibiotic group were fed the basal diet supplemented with 0.1 g/kg zinc bacitracin premix. And the birds in probiotic group were fed the basal diet supplemented with 1 g/kg probiotic premix. The experiment was carried out for 70 days. The results showed as follows: 1) the body weights of chickens at 70 days of age in probiotic and antibiotic groups were both significantly increased compared with the control group (P<0.05). There was no significant difference in body weight between the chickens in probiotic group and the chickens in antibiotic group ( P>0.05) . 2) The apparent utilization rate of crude protein in probiotic group tended to be improved by 8.7% ( P=0.054) , and the apparent utilization rate of calcium in probiotic group was significantly improved by 22. 96% ( P<0. 05) compared with the control group. The apparent utilization rate of energy in antibiotic group was significantly improved compared with the control group (P<0.05). 3) Compared with the control group, the cecum microbial diversity and the abun-dance of beneficial bacteria in cecum were increased, whereas the abundance of pathogen in cecum was de-creased in probiotic group;the abundance of pathogen in cecum was decreased, but the cecum microbial diver-sity and the abundance of beneficial bacteria in cecum were also decreased in antibiotic group. In conclusion, dietary probiotic can promote the growth in early life of layer chickens and improve the nutrient utilization and the structure of intestinal flora of layer chickens, which is helpful to the health of layer chickens. In addition, probiotics are more conducive to intestinal health compared with antibiotics.关键词
