天水市规模养鸡场禽白血病流行病学调查

Epidemiological Investigation of Avian Leucosis in LargeScale Chicken Farms in Tianshui City

摘要:

为了解甘肃省天水市鸡禽白血病的流行情况，本文采用实时荧光PCR方法对2020～2021年采集的24个规模鸡场的480份泄殖腔拭子进行了病原学检测。结果显示，24个规模场中阳性场18个，场点阳性率为73.33%；480份样品中阳性样品203份，样品阳性率42.29%。其中不同用途的鸡禽白血病感染率不同，360份蛋鸡样品中阳性138份，阳性率38.33%；120份肉鸡样品中阳性65份，阳性率54.17%。结果表明，禽白血病病毒在天水市规模鸡场存在普遍流行的现象，且肉鸡的感染率高于蛋鸡。

Abstract:

In order to understand the prevalence of Avian Leucosis in Tianshui City, Gansu Province, this paper used realtime fluorescent PCR method to carry out pathogenic detection on 480 cloacal swabs collected from 24 largescale chicken farms from 2020 to 2021. The results showed that 18 of the 24 scale farms were positive, with a positive rate of 73.33%. Among the 480 samples, 203 were positive, and the positive rate of the samples was 42.29%. Among them, the infection rate of Avian Leucosis for different purposes is different. Among the 360 laying hen samples, 138 were positive, and the positive rate was 38.33%. Among the 120 broiler samples, 65 were positive, with a positive rate of 54.17%. The results showed that Avian Leucosis virus was prevalent in largescale chicken farms in Tianshui City, and the infection rate of broiler chickens was higher than that of laying hens.
