| 摘 要： | 试验从健康AA肉鸡肠道分离出一株芽孢杆菌,对该菌株进行了培养特性观察、生化鉴定、16S rRNA序列分析,并研究了该菌株的安全性及其对鸡免疫器官的影响。结果表明,该菌株为地衣芽孢杆菌,命名为BL-C;该菌株对AA肉鸡不具有致病性,可显著加快雏鸡的生长、促进免疫器官的发育,为其进一步应用于畜禽养殖提供理论依据。

| Abstract: | An isolate of Bacillus licheniformis was isolated from intestine of health AA broiler, and identified by colonial morphology, culture characteristic, biochemistry reaction, 16S rRNA sequencing analysis, study on the security of the isolate and its effect on immune organs of chickens. The results showed that the isolate was Bacillus licheniformis, named BL-C. The isolate had no pathogenicity on AA chickens, and could significantly accelerate its growth, promoting the development of immune organs of chicks. The study provided theoretical basis for its further application in animal breeding. |
