Abstract

This experiment was conducted to investigate the effects of Clostridium butyricum on thigh muscle lipid metabolism of broilers. A total of 192 one-day-old male Arbor Acres (AA) broilers were randomly allocated into 2 groups with 6 replicates per group and 16 broilers per replicate. Birds in the control group were fed a basal diet, and the others in the test group were fed the basal diet supplemented with 1×109 CFU/kg Clostridium butyricum. The experiment lasted for 42 days. The results showed as follows, compared with the control group: 1) dietary supplementation of Clostridium butyricum significantly increased the thigh muscle intramuscular fat content of broilers at 21 days of age (P<0.05), but had no effect on the thigh muscle intramuscular fat content of broilers at 42 days of age (P>0.05). 2) Dietary supplementation of Clostridium butyricum significantly decreased the thigh muscle hormone sensitive lipase activity of broilers at 21 days of age (P<0.05), significantly increased the thigh muscle lipoprotein lipase (LPL) activity of broilers at 21 days of age (P<0.05), and tended to increase the thigh muscle LPL activity of broilers at 42 days of age (0.05<P<0.10). 3) Dietary supplementation of Clostridium butyricum significantly decreased the serum free triiodothyronine content of broilers at 21 days of age (P<0.05). 4) Dietary supplementation of Clostridium butyricum significantly decreased the thigh muscle adipose triglyceride lipase mRNA expression of broilers at 21 days of age (P<0.05). In conclusion, dietary supplementation with Clostridium butyricum can positively affect intramuscular fat content by regulating the lipid metabolism related enzyme activities and gene expression in the thigh muscle of broilers at 21 days of age.
