Effects of Butyrin on Growth Performance,Nutrient Apparent Digestibility, Slaughter Performance,Intestinal Morphology and Microbial Flora of Broilers
摘要
Abstract
This experiment was conducted to investigate the effects of butyrin on the growth per‐formance ,nutrient apparent digestibility ,slaughter performance ,intestinal morphology and micro‐bial flora of broilers .A total of 384 1‐day‐old Rose 308 broilers were selected and randomly divid‐ed into 4 groups ,4 replicates per group and 24 broilers per replicate .The blank control group was fed on basal diet ,the experimental groups were fed on basal diet supplemented with 250 ,500 and 750 g/t butyrin ,respectively ,which replaced 40% oil of the basal diet .The experiment lasted for 42 days .The result showed that compared with the blank control group ,diets supplemented with butyrin had an promoting effect on the performance of broilers ,and the middle dose group (500 g/t) was the best .The slaughter performance of supplemented groups showed a tendency to be improved ,but there was no significant difference with blank control group (P> 0 .05);The height of duodenum and jejunum villus of middle supplemented group were significantly improved (P<0 .05) ,and the crypt depth of supplemented groups tended to be reduced ,but there was no significant difference (P>0 .05);Compared with the blank control group ,the apparent digestibili‐ty of crude fat and crude fiber of middle supplemented group were significantly improved (P<0.05);The amount of Escherichia coli of middle supplemented group was significantly decreased (P<0 .05);And the amount of Lactobacillus was significantly improved (P< 0.05) .In conclu‐sion ,basal diet supplemented with butyrin could promote the grow th performance ,increase the nutrient digestibility ,improve the intestinal morphology and microbial flora of broilers .The best supplemented level of butyrin for diets was 500 g/t .关键词
