Research On Livestock And Poultry Breeding Industry Pollution And Eco-management

With the improvement of people's living standards, the demands of meat, eggs and milk was increasing continuously which had taken the development of livestock and poultry industry in Zhejiang province. The waste from the livestock and poultry production was very great, which in some extent has affected the surrounding ecological environment. So it had great practical significance to estimate the amount of the waste, the treatment and management system.Through questionnaire and field survey to livestock and poultry industries, these methods had tried to find out the status, treatment and recycle way to deal with the livestock and poultry waste in rural areas in Zhejiang Province, as well as the environment protection awareness of the farmers. According to different classification questionnaire, data was analyzed by Excel. The result demonstrated that regional difference was large and the community was short of environment awareness. Excreta parameters of poultry excrements were determined, based on figures of Zhejiang statistical yearbook from 2005 to 2008 years, and then the amount of poultry excrements, feces loading in farmland and alarming values for loading amount of animal feces were all estimated. The result demonstrated that the amount of livestock and poultry excrements were all above 30 million ton. The amount of pig excrements was largest, and was followed by poultry excrements. Jiaxing was on the top of the amount of livestock and poultry excrements. In these four years the average pollution loading of the province reached 13.9.4 t·hm-2·a-1, Quzhou, Jiaxing and Hangzhou exceed the average of the pollution loading every year.In the future, the countermeasures to deal with pollution resulted from poultry excrements should include the following aspects: enact and practice index system of livestock farm, perfect eco-management of livestock and poultry breeding industry, construct exemplary base for ecological environment protection, improve level of cycle disposaling livestock and poultry breeding industry waste, strengthen education of waste cycle utilization.
