摘要
近几十年来,国内外养猪业纷纷采用零排放的生物发酵床技术来解决养殖过程中猪粪尿污染带来的环境问题。但是该技术存在诸多问题,如成本过高、发酵床发酵过程中温度过高以及产生毒害气体等。结合发酵床养猪方法与水泥地养猪方法的优缺点,本文设计一种更适合我国南方地区气候条件的无污染养猪法:薄垫料—外发酵养猪法,并将其与传统养猪模式进行对比实验,试验指标包括:垫料用量、垫料成本、发病率、出栏率、耗水量、体质量增量和料重比等,结果表明:该养猪法比传统的水泥地养猪法和传统发酵床养猪法环保、省工、省药、省水,达到低成本、低排放、无臭味生态养猪的效果。
In recent decades, zero emissions fermentation bed technology has been used to solve the excreta of pig from polluting the environment in pig industry at home and abroad. But, in application, there exist many problems,such as,high temperature of the fermentation bed,high cost and the production of harmful gas. By combining the advantages and disadvantages of the fermentation bed raising pig method with cement floor raising pig method,this paper devise a new raising-pig method--thin mat fermentation bed method, which is more suitable for the south areas. Compared with the former pig feeding mode in the following aspects, such as ~ costs of mat, incidence of disease, slaughtering rate, water consumption, growth increment in weight ,feed amount and the feed/gain ratio ,the results show that the new method is more environmental friendly in saving labor,provincial medicine and water,which is an ecological raising-pig method of low cost,low emission and no smell.
