摘要
养殖周期相对较长和成本较高是制约清远麻鸡经济效益的关键因素,采用微生物制剂调控清远麻鸡生长性能具有良好的应用前景。该文采用自主选育的侧孢短芽孢杆菌BL01作为微生物态制剂,研究BL01对清远麻鸡生长性能、抗氧化指标及肠道微生物的影响。结果表明:经过30天的饲喂,在饮水中添加BL01能够显著提高清远麻鸡的末重(提高2.7%,P<0.05)和平均日增重(提高2.9%,P<0.05),降低料重比(降低5.2%,P<0.05),同时提高了血清总抗氧化酶(total antioxidant capacity,T-AOC)和超氧化物歧化酶活力(superoxide dismutase,SOD),显著降低了肠道有害菌Eschichia-Shigella(降低15.98%)的比例。以上结果表明饮水添加BL01可以改善清远麻鸡生长性能,增强机体抗氧化能力和调控肠道菌群结构。
The feeding with relatively long time and high cost were the key factors restricting the economic benefits of Qingyuan partridge chicken.The use of microbial agents to regulate the growth performance of Qingyuan partridge chicken had a good application prospect.In this study,the effects of BL01 on growth performance,antioxidant indexes and intestinal microorganisms of Qingyuan partridge chickens were studied by using the selfselected Brevibacillus laterosporus BL01 as a microbial preparation.After 30 days of feeding with BL01,the final body weight and average daily gain(P<0.05)were significantly increased 2.7%and 2.9%(P<0.05),respectively.And in meanwhile the ratio of feed to gain was decreased 5.2%(P<0.05).The activity of serum T-AOC and SOD significantly were increased(P<0.05).The proportion of intestinal harmful bacteria EschichiaShigella was significantly reduced 15.98%(P<0.05).Those results indicated that adding BL01 in drinking water could improve the growth performance,enhance the antioxidant capacity and regulate the gut microbiome composition of Qingyuan partridge chicken.
