本试验旨在研究凝结芽孢杆菌对黄羽肉鸡生产性能、血清生化指标及抗氧化功能的影响。选取1日龄黄羽肉鸡360羽,随机分为4组(每组6个重复,每重复15羽)：Ⅰ组(对照组)饲喂基础饲粮,Ⅱ、Ⅲ、Ⅳ组饲喂分别添加100、200、300 mg/kg 凝结芽孢杆菌(活菌数为1×109 CFU/g)的试验饲粮,试验期70 d。结果表明：与对照组相比,1)饲粮添加200 mg/kg凝结芽孢杆菌显著提高了全期肉鸡平均日增重、成活率和胸肌率(P<0.05),显著降低了全期料重比( P<0.05)；2)饲粮添加200 mg/kg凝结芽孢杆菌显著或极显著提高了28、70日龄肉鸡血清碱性磷酸酶活性( P<0.05或P<0.01)、70日龄血清白蛋白和总蛋白含量( P<0.05),极显著降低了70日龄血清尿素氮含量(P<0.01)；3)饲粮添加200 mg/kg凝结芽孢杆菌显著提高了肉鸡28、70日龄血清中总抗氧化能力、超氧化物歧化酶活性和70日龄血清过氧化氢酶活性(P<0.05),极显著或显著降低了28、70日龄血清丙二醛含量( P<0.01或P<0.05)。由此可见,结合生产性能、血清生化指标及抗氧化功能指标,1~70日龄黄羽肉鸡饲粮添加200 mg/kg(2×108 CFU/kg)凝结芽孢杆菌效果最佳。

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.
