【摘要】：自2013年初以来,对闽赣两省相近区域内的部分舍内地面加水域圈养、舍内地面饲养、网床小栏饲养和笼养4种模式下的同一品种开产蛋鸭群发生的疫病开展了定点跟踪调查和病毒性、细菌性疫病感染检测,发现4种不同养殖模式的蛋鸭疫病感染率、发生的疫病种类及同一疫病的严重程度均存在较大差异,其中以舍内地面加水域圈养模式的蛋鸭病毒性和细菌性疫病感染率最高达84.4%,发生的疫病种类最多达10种,发生同一种疫病时感染的阳性率更高(如禽坦布苏病毒感染阳性高达22.9%),致病菌的耐药谱更宽(如分离鉴定的大肠杆菌耐10种及以上药物的菌株占84.2%);而网床小栏饲养、笼养两种模式下的蛋鸭发生的疫病种类相对较少,为5~6种,其主要疫病为禽坦布苏病毒病、禽流感和大肠杆菌病,尤其是笼养蛋鸭发生病毒性和细菌性疫病感染率为26.5%、发生同一种疫病时感染的阳性率最低(如致病性大肠杆菌感染的阳性仅为7.8%)。以上结果表明,蛋鸭养殖模式的良莠与疫病发生的种类及其感染的程度直接相关,可见促进蛋鸭养殖模式的转型升级是防控疫病重要的生物安全举措。
[Abstract]:Since the beginning of 2013, some of the houses in the adjacent areas of Fujian and Jiangxi provinces have been kept in captivity and raised on the ground. The incidence of blight in the same breed of laying duck was investigated by spot tracking, virus infection and bacterial blight infection, and the infection rate of four different breeding models was found. There were great differences in the types of blight and the severity of the same blight. Among them, the infection rate of virus and bacterial blight of laying duck with the model of ground and water in captivity was up to 84.4%, and that of 10 kinds of blight occurred at most. The positive rate of infection was higher when the same epidemic occurred (for example, the positive rate of avian tambusuvirus infection was as high as 22.9%, and the spectrum of drug resistance of pathogenic bacteria was wider (such as 84.2% of strains isolated and identified as resistant to 10 or more drugs), while the strains raised in netted beds were raised. There are relatively few kinds of epidemic diseases occurring in laying ducks in captivity, which are 5 or 6 species. The main epidemic diseases are avian tampon virus, avian influenza and Escherichia coli. In particular, the infection rate of viral and bacterial blight in cage laying ducks was 26.5, and the positive rate of infection was the lowest when the same disease occurred (e.g., the positive rate of pathogenic Escherichia coli infection was only 7.8%). The results showed that the herbicide was directly related to the species of epidemic disease and the degree of infection, so it was an important biological safety measure to promote the transformation and upgrading of the breeding model of laying duck.
