Study On Resource Utilization Of Broiler Manure And Its Influencing Factors

With the rapid development of China's animal husbandry,the total scale of livestock and poultry farming continues to expand,and the degree of intensive farming continues to increase.Pollution emissions from livestock and poultry farming have become an important source of environmental pollution in China.If it is not handled or used,it will not only cause waste of resources,but also endanger the health of livestock and poultry and human bodies,and seriously affect the environment and the sustainable development of animal husbandry.Broiler are the second largest breed of livestock and poultry in my country.Broiler manure is an important part of livestock and poultry pollution.Research on the utilization of broiler manure resources can help promote the convenience of livestock and poultry manure.This article analyzes the relevant background and main models of the utilization of broiler manure resources in China;by conducting a scale survey and analysis of the relevant situation of the utilization of broiler manure resources by farmers in major broiler producing provinces(regions)such as Henan,Hebei,Shandong,Yunnan,Guangxi,and Anhui.The current status of the utilization of broiler manure resources in farmers in China;from the perspective of cost-benefit analysis,the costs and benefits of different broiler manure resource utilization methods are calculated and compared;by using the disordered multi-class Logit model,the impact of breeding factors for households to choose the method of resource utilization of broiler manure;finally put forward policy suggestions on the resource utilization of broiler manure.The main conclusions obtained are as follows: First,broiler manure resource utilization model mainly includes fertilizer,energy and feed.Through the survey results of six provinces(regions)in China,it is found that the current utilization methods of broiler manure resources in broiler farmers in our country include free gift of broiler manure,sale of fresh manure,self-use of manure(including organic fertilizer),manure(including organic fertilizer))Five species for sale and use for feed.Among them,the four types of free use of broiler manure,sale of fresh manure,self-use of manure(including organic fertilizer),and sale of manure(including organic fertilizer)all belong to the mode of utilization of broiler manure.Second,the difference in the cost and benefit of the utilization of broiler manure resources is mainly due to the difference in natural endowments and differences in breeding scale between the north and the south.Farmers in the southern region use manure for their own use,feed for their own use,sale of fresh manure,and the cost of manure(including organicfertilizer)is higher than in the north,but at the same time,the profit of selling fresh manure and manure(including organic fertilizer)in the southern region is higher than that in the northern region.The larger the scale of breeding,the lower the cost of manure for own use,and the lower the profit from the sale of fresh manure and manure.The third is whether the farmers themselves operate planting,broiler breeds,broiler production industrialization mode,regional characteristics,government subsidies,and government departments' supervision,etc.have a significant impact on the farmers' use of broiler manure resources.Based on the above conclusions,it is recommended to increase efforts to support and guide farm households in the utilization of broiler manure resources,and give appropriate policy preferences and financial subsidies to farms equipped with manure treatment facilities and equipment;establish and improve a market system for the utilization of broiler manure resources.The broiler manure resource utilization product industry chain realizes the effective allocation of the market resources of broiler manure resource utilization products;improves the external environment of broiler manure resource utilization,accelerates the research and promotion of advanced production equipment,and encourages the development of third-party broiler manure purchasers for small and medium scale The disposal of broiler manure resources in farms has been improved;the training and promotion of farmers' breeding and utilization of broiler manure have been strengthened.Establish a relevant system for the management of broiler manure nutrients in my country,and encourage large-scale farms to integrate the use of broiler manure and make use of the manure resources in accordance with the manure nutrient management plan.
