Effects of Tributyrin 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 tributyrin on growth performance, nutri-ent apparent digestibility, slaughter performance, intestinal morphology and microbial flora of broilers.A total of 1 800 one-day-old male Avian broilers were selected and randomly divided into 6 groups with 6 replicates per group and 50 broilers per replicate.Broilers in the control group was fed a basal diet, and broilers in the experimental groups were fed the basal diets supplemented with 0 .10%, 0 .15%, 0 .20%, 0 .30% and 0 .40% tributyrin, respectively.The experiment lasted for 42 days.The results showed as follows:diets sup-plemented with tributyrin tended to improve the growth performance of broilers, and the 0 .20% tributyrin group reached the highest.2 ) Compare with the control group, the apparent digestibility of ether extract and crude fiber in 0.20%tributyrin group was significantly increased ( P<0.05); the slaughter performance ten-ded to be improved, but had no significant change ( P>0 .05 ); the villus height in duodenum and jejunum was significantly increased (P<0.05);the crypt depth in duodenum and jejunum tended to be decreased, but had no significant change (P>0.05);the number of Lactobacillus in cecum was significantly increased (P<0.05), and the number of Escherichia coli in cecum was significantly decreased (P<0.05).In conclusion, diets supplemented with tributyrin can promote the growth performance, increase the nutrient digestibility and improve intestinal morphology and microbial flora of broilers.The optimal supplemented level of tributyrin is 0.20% for broilers.关键词
