【摘要】：基于中国5个鸡蛋主产省份811份规模养殖户的调研数据,利用统计分析方法和EBM模型在测算蛋鸡污染物排放量及治理投入的基础上评估了养殖户蛋鸡养殖的适度规模。结果表明:蛋鸡污染物排放量及治理投入存在规模差异,30 000~49 999只的蛋鸡养殖场污染物平均排放量以及治理投入最低。考虑污染物排放及治理投入,中国鸡蛋主产区规模养殖户的蛋鸡养殖规模以30 000~49 999只最为适度,该规模区间的养殖指标、效益及效率是相对最优或最高的。在中国鸡蛋主产省份以1万只蛋鸡以下为主要养殖区间的发展态势下,规模养殖的潜力仍然可待挖掘,规模化水平需进一步提升。
[Abstract]:Based on the survey data of 811 large scale farmers in five major egg production provinces in China, Based on the statistical analysis method and EBM model, the appropriate scale of laying hens was evaluated on the basis of measuring the discharge amount of pollutants and the investment of treatment. The results showed that the amount of pollutants discharged and the existing scale of the management investment were obtained. The average discharge of pollutants and the control input were the lowest in 30 000 ~ 49,999 laying hens. Considering the pollutant discharge and control input, In the major egg producing areas of China, the breeding scale of laying hens was 30 000 to 49 999, and the breeding index of this scale range was the most appropriate. The benefit and efficiency are relatively optimal or the highest. Under the development situation of 10,000 laying hens as the main breeding section in the main egg production province in China, the potential of scale breeding is still to be excavated, and the scale level needs to be further improved.
