【摘要】：为探究不同水平的凝结芽孢杆菌制剂对朝鲜鹌鹑生长性能、蛋品质和血清抗氧化指标的影响,试验选取300只蛋用朝鲜鹌鹑,随机分为5组,每组设3个重复,每个重复20只。对照组饲喂基础日粮,4个试验组分别在基础日粮中添加0.1%、0.15%、0.2%和0.3%的凝结芽孢杆菌制剂。结果表明:与对照组相比,试验3组的平均日增重显著提高(P0.05);试验1、2、3和4组的蛋白高度和哈夫单位极显著高于对照组(P0.01),试验1、2和3组的蛋壳强度极显著高于对照组(P0.01);与对照组相比,试验3组血清中的过氧化氢酶(CAT)含量显著提高(P0.05);与对照组相比,试验1、2和3组血清中的总抗氧化能力(T-AOC)极显著提高(P0.01),试验2组血清中的丙二醛(MDA)含量极显著降低(P0.01)。以上结果表明,日粮中添加凝结芽孢杆菌制剂可提高朝鲜鹌鹑的生长性能,改善蛋品质,提高血清抗氧化能力,添加量以0.2%较为适宜。
[Abstract]:In order to investigate the effects of different levels of Bacillus coagulans on the growth performance, egg quality and serum antioxidant index of Korean quails, 300 quails were randomly divided into 5 groups, with 3 replicates in each group with 20 quails per replica. The control group was fed with basal diet, and the four experimental groups were supplemented with 0.1% 0.15% and 0.3% Bacillus coagulans in the basal diet, respectively. The results showed that: compared with the control group, the average daily gain of the three groups increased significantly (P0.05); The protein height and Hafu unit of groups 1 and 4 were significantly higher than that of control group (P0.01), and the eggshell strength of groups 1 and 3 was significantly higher than that of control group (P0.01). Compared with the control group, the serum catalase (CAT) content in the three experimental groups was significantly increased (P0.05). Compared with the control group, the total antioxidant capacity (T-AOC) in the serum of experimental group 1 and group 3 was significantly increased (P0.01), and the content of malondialdehyde (MDA) in serum of group 2 was significantly decreased (P0.01). The results showed that the addition of Bacillus coagulans in diet could improve the growth performance of Korean quails, improve the quality of eggs and increase the antioxidant capacity of serum. The addition of 0.2% was more suitable.
