Effects of Bacillus coagulans on Performance, Serum Biochemical Indices and Antioxidant Function of Yellow Broilers
摘要
Abstract
This experiment was conducted to investigate the effects of Bacillus coagulans on performance, ser-um biochemical indices and antioxidant function of yellow broilers. A total of 360 one-day-old yellow broilers were randomly allocated to 4 groups with 6 replicates per group and 15 chicks per replicate. Broilers in the con-trol group ( groupⅠ) were fed a basal diet, and broilers in groupsⅡ,ⅢandⅣwere fed the basal diet add-ed with 100, 200 and 300 mg/kg Bacillus coagulans (viable count was 1×109 CFU/g), respectively. The ex-periment lasted for 70 days. The results showed as follows: compared with the control group, 1) diet added 200 mg/kg Bacillus coagulans significantly increased average daily gain, survival rate and percentage of breast muscle ( P<0.05) , and significantly decreased the ratio of feed to gain in the whole period ( P<0.05) . 2) Diet added 200 mg/kg Bacillus coagulans significantly increased serum alkaline phosphatase ( ALP) activity at age of 28 and 70 days ( P<0.01 or P<0.05) , and significantly increased the content of albumin ( ALB) and total protein (TP) in serum at age of 70 days (P<0.05), and significantly decreased the content of urea nitrogen (UN) in serum at age of 70 days (P<0.01). 3) Diet added 200 mg/kg Bacillus coagulans significantly in-creased serum total antioxidant capacity ( T-AOC) , superoxide dismutase ( SOD) activity at age of 28 and 70 days and catalase ( CAT) activity at age of 70 days ( P<0.05) , and significantly decreased serum malondialde-hyde ( MDA) content at age of 28 and 70 days ( P<0.01 or P<0.05) . In conclusion, base on indices of per-formance, serum biochemical indices and antioxidant function, the effects of adding 200 mg/kg ( 2 × 108 CFU/kg) Bacillus coagulans in the diet of yellow broilers aged from 1 to 70 days are optimal.关键词
