蛋鸡养殖户病死鸡无害化处理行为研究

Research on Farmers' Bio-safety Disposal of Sick or Dead Layer

病死鸡的无害化处理问题已经成为保障食品安全、生态环境安全以及促进蛋鸡养殖业健康发展的关键因素之一。论文利用实地调研数据,采用Logistic模型和Tobit模型分析了蛋鸡养殖户病死鸡无害化处理行为。研究表明:蛋鸡养殖户主要采取无害化方式处理病死鸡,无害化处理程度约为90%。可通过提高户主受教育程度和增加蛋鸡养殖技术培训来提高养殖户的素质,从而进一步提升养殖户无害化处理病死鸡的水平,同时,养殖户的风险规避意识有利于其选择无害化方式处理病死鸡,并保持较高水平的无害化水平。此外,养殖场离城镇的距离越近,则由于受到监管以及城市环境建设的影响,养殖户为了继续养殖会保持病死鸡无害化处理的高水平。

Bio-safety disposal of sick or dead layers has become critical in food and ecological environ- ment safety, and health development of the poultry industry. Based on field research, this paper analyzed farmers bio-safety disposal of sick or dead layers with the logistic model and Tobit model. The study showed that about 90% farmers practised the bio-safety disposal of sick or dead layers, and farmers could be better educated and trained to further improve their bio-safety disposal of ill or dead layers. Also, farmers attitude towards risk aversion helped them choose bio-safety disposal and maintain high level. In addition, when close to cities or towns, farmers often keep a high level of bio-safety disposal, because of related supervision and urban environment construction.
