The experiment was conducted to study the effect of Clostridium butyricum on production performance, serum biochemical indexes and economic benefits of laying hens. Four thousand 38-week-old Hyline brown laying hens were randomly divided into four groups with five replicates in each group and 200 laying hens in each replicate. The laying hens in control group were fed with basal diet, and the laying hens in experimental groups were fed with basal diet supplemented with 250, 500 and 1 000 mg/kg Clostrium butyric, respectively. The pre-test period lasted for 7 d and the formal test period lasted for 60 d. The results showed that the qualified egg rate of 1 000 mg/kg group was significantly higher than that of control group ( P<0.05), and the feed to egg ratio was significantly lower than that of control group ( P<0.05). The Haugh unit of eggs in experimental groups was significantly higher than that in control group ( P<0.05). The intestinal Lactobacillus in 500 mg/kg group and 1 000 mg/kg group was significantly higher than that in control group ( P<0.05), and the number of Escherichia coli in 500 mg/kg group was significantly lower than that in control group ( P<0.05). The T-AOC, GSH-Px and SOD activity in experimental groups were significantly higher than those in control group ( P<0.05), and the MDA content was significantly lower than that in control group ( P<0.05). The content of IgG in serum of laying hens in 1 000 mg/kg group was significantly higher than that in control group ( P<0.05), and the content of IgM in serum of laying hens in experimental groups was significantly higher than that in control group ( P<0.05). The profit per layer of the experimental groups was 8.36%, 17.72% and 19.40% higher than that of control group, respectively. The experiment indicates that dietary supplementation of Clostridium butyricum can improve the production performance and egg quality, and effectively improve the body health level. The dietary supplementation level of Clostridium butyricum is recommended to be 1 000 mg/kg. [ABSTRACT FROM AUTHOR] |
