| With the rapid development of large-scale dairy farming,the generation of a large amount of manure has caused environmental pollution and resource waste,and livestock manure cannot be absorbed through the regional planting industry.The phenomenon of separation between planting and breeding is becoming increasingly severe.In recent years,the state has issued a series of relevant policies to support the combination of breeding and planting,and the model of combination of breeding and planting in dairy industry has achieved certain results.However,in practical operation,some dairy farmers lack experience in the integration of planting and breeding,resulting in unreasonable allocation of input-output resources between the planting and breeding industries,low production efficiency of dairy farming,and other problems,making it difficult to fully utilize the advantages of the integration of planting and breeding.Therefore,from the perspective of input,output and efficiency,this thesis analyzes the problems of dairy farms in developing the combination of breeding and planting mode,tries to help dairy farms develop the combination of breeding and planting mode,and provides reference and reference for realizing cost saving and income increase and sustainable development of dairy farming industry.This article takes the pilot banner(county)of integrated planting and breeding in Inner Mongolia Autonomous Region as the research area to conduct on-site research on integrated planting and breeding dairy farms and non integrated planting and breeding dairy farms.First,the input and output of the two dairy farms were statistically described and analyzed.Then,the production efficiency of dairy farms was measured by Data envelopment analysis(DEA)and Stochastic Frontier production function(SFA).The SFA method was used to study the main factors affecting the production efficiency loss of dairy farms.Research has found that the DEA method calculates a comprehensive efficiency of 0.794 for planting and breeding combined dairy farms,and 0.813 for non planting and breeding combined dairy farms.The comprehensive efficiency of non planting and breeding combined dairy farms is 0.019 higher than that of planting and breeding combined dairy farms.The difference in comprehensive efficiency between the two modes is not significant,and the reason for the low comprehensive efficiency of the two modes of dairy farms mainly depends on the low pure technical efficiency;However,through input redundancy and output insufficiency,it is found that the coarse feed redundancy of the non planting and breeding combination mode is higher than that of the planting and breeding combination mode,and there is little difference between the concentrate feed redundancy,labor redundancy and fixed asset redundancy of the two modes of dairy farms,while the output insufficiency of the planting and breeding combination dairy farms is higher;By using the SFA method to calculate technical efficiency,it was found that when the scale of cow farming is less than 500 heads,the average technical efficiency of the breeding and breeding combined dairy farm is lower than that of the non planting and breeding combined dairy farm,while when the scale is between 500 and 5850 heads,the average technical efficiency of the planting and breeding combined dairy farm is higher than that of the non planting and breeding combined dairy farm;By analyzing the influencing factors of technological efficiency loss,it was found that the education level,farming years,farming scale,and environmental supervision of dairy farmers have a significant promoting effect on improving the technological efficiency of dairy farms.Finally,based on the research results,this article proposes relevant suggestions such as strengthening agricultural technology training related to the integration of planting and breeding,moderately increasing the scale of breeding combined with planting and breeding,and improving the quality of practitioners. |
