Abstract

This experiment was conducted to investigate the effects of tributyrin on growth performance, nutrient 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 supplemented 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 tended 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.
