【摘要】：本试验旨在研究复合微生物发酵玉米蛋白粉对肉仔鸡生长性能、肠道微生物数量和抗氧化能力的影响。选取7日龄黄羽肉仔鸡150只,随机分为3组,每组10个重复,每个重复5只鸡。对照组饲喂不添加发酵玉米蛋白粉的基础饲粮,试验组分别饲喂添加5%和10%发酵玉米蛋白粉的试验饲粮。试验期49 d。结果表明,与对照组相比:1)饲粮添加5%和10%的发酵玉米蛋白粉能够显著提高肉仔鸡的平均日采食量和平均日增重(P0.05),并且饲粮添加10%的发酵玉米蛋白粉能够显著降低料重比(P0.05);2)饲粮添加10%的发酵玉米蛋白粉能够显著或极显著提高28日龄的肝脏指数、肾脏指数以及56日龄的肾脏指数、胸腺指数(P0.05或P0.01);3)饲粮添加10%的发酵玉米蛋白粉能够极显著降低28日龄盲肠大肠杆菌数量(P0.01),饲粮添加5%和10%的发酵玉米蛋白粉能够极显著增加28和56日龄盲肠乳酸杆菌的数量(P0.05);4)饲粮添加5%和10%的发酵玉米蛋白粉能够极显著提高血清抗超氧阴离子自由基和抑制羟自由基能力(P0.01),并极显著降低28日龄血清丙二醛含量(P0.01)。由此可见,饲粮添加发酵玉米蛋白粉能够有效促进肉仔鸡生长,优化肠道菌群结构,提高抗氧化能力。
[Abstract]:The purpose of this experiment was to study the effects of compound microbial fermentation corn protein meal on growth performance, intestinal microorganism quantity and antioxidant capacity of broilers. 150 yellow broilers of 7 days old were randomly divided into 3 groups with 10 replicates in each group and 5 chickens in each group. The control group was fed basic diet without fermenting corn protein powder, and the experimental group was fed with 5% and 10% fermented corn protein powder respectively. The experimental period was 49 days. The results show that Compared with the control group, addition of 5% and 10% fermented corn protein powder significantly increased the average daily intake and average daily gain of broilers (P0.05), and 10% fermented corn protein meal significantly decreased the ratio of feed to weight (P0.05). Dietary supplementation of 10% fermented corn protein powder significantly or extremely significantly increased liver index at 28 days of age. The kidney index and the kidney index at 56 days old, Thymus index (P0.05 or P0.01) was significantly reduced by adding 10% fermented corn protein powder to diet (P0.01), and 5% and 10% of fermented corn protein powder added to diet significantly increased the lactate content of 28 and 56 days old caecum (P0.01). Addition of 5% and 10% corn protein powder could significantly improve the ability of resisting superoxide anion free radical and inhibiting hydroxyl radical (P0.01), and decrease the content of malondialdehyde in serum of 28 days old (P0.01). It can be seen that adding fermented corn protein powder into the diet can effectively promote the growth of broilers, optimize the intestinal microflora structure, and improve the antioxidant capacity.
