摘要:

为了解疫病净化与疫病发病率之间的关系,以禽白血病和鸡白痢为具体净化的病种,收集全国297个规模化养鸡场2011-2015年的调查数据。首先进行样本均值T检验,判断已净化养鸡场与未净化养鸡场的疫病发病率是否存在显著差异,并在此基础上利用面板Tobit模型进行计量分析。结果表明:已开展禽白血病净化和鸡白痢净化的养鸡场,鸡群的疫病发病率较未净化养鸡场分别下降了1.416%和1.370%。分不同成长阶段来看,已开展禽白血病净化的养鸡场,产蛋鸡和种用公鸡的禽白血病发病率较未净化养鸡场有了明显降幅,分别下降了1.873%和0.949%。已开展鸡白痢净化的养鸡场,雏鸡、育成鸡和种用公鸡的鸡白痢发病率比未净化养鸡场分别下降了2.360%、0.904%以及0.591%。此外,研究发现增加疫苗投入以及采用全进全出的饲养方式可有效降低疫病的发病率。最后,建议国家加大对动物疫病净化的宣传,让更多的养殖场(户)认识到动物疫病净化的重要性,在结合自身实际条件的基础上,积极开展疫病净化工作。

Abstract:

In order to understand the relationship between the disease eradication and the incidence of epidemics disease, the survey data of 297 large-scale chicken farms in China from 2011 to 2015 were collected, avian leukosis and pullorum disease were selected as the specific eradication diseases. At first, the sample mean T-test was performed to determine whether there were significant differences in the incidence of diseases between purified farms and unpurified farms. Based on this, the Tobit model was used for further quantitative analysis. The results showed that the incidence of epidemic diseases in those farms which have carried out the eradication of avian leukosis and pullorum disease had dropped by 1.416% and 1.370% respectively compared with that of unpurified farms. From the points of different growth state, the incidence of avian leucosis of laying hens and breeder cocks in those farms which had eradicated avian leucosis had reduced by 1.837% and 0.949% respectively compared with that of unpurified farms. The incidence of pullorum disease of chicks, adult chickens and breeder cocks in those farms which had eradicated pullorum disease had decreased by 2.360%, 0.904% and 0.591% respectively compared with that of unpurified farms. In addition, the study found that increasing vaccine input and adopting all-in and all-out feeding method can effectively reduce the incidence of diseases. Lastly, it is suggested that the state should increase the publicity of animal disease eradication, so more farms (households) could recognize the importance of animal disease eradication, and combine with their own actual conditions, in order to carry out the eradication of the disease optimistically.
