发酵床养殖

猪发酵床养殖中芽孢杆菌菌株的筛选、鉴定及产蛋白酶条件的优化

Screening and Identification of Bacillus with High Activity from Swine Deep Litter System and the Optimization of Protease Produce

发酵床养殖模式是基于利用自然或人工添加的微生物降低动物粪便污染、改善畜舍环境的一种养殖技术。

Deep litter system is a farming techniques based on reducing the animal wastes pollution and improving the barns environment .

发酵床养殖作为新型养殖技术，自从引入我国后，被大力地推广和使用，为解决畜牧环境污染问题带来了新希望。

Since our country introduced it , as a new rearing technique , deep-litter-system has been vigorously promoted , which can effectively solve the problem of animal husbandry and environmental pollution .

其氨氮去除率也达到了70%以上。该复合菌剂为微生态发酵床养殖及粪便堆肥提供了微生物菌种资源。

The removal rate of the strain of ammonia nitrogen was up to 70 % , which provided germplasm resources for the production of microecology fermentation bed farming and manure compost .

在整个试验过程中，随着饲养的进行，发酵床养殖模式垫料中枯草芽孢杆菌、放线菌和酵母菌数量下降较小幅度；随着饲养时间的延长，大肠杆菌和霉菌数量有上升趋势。

During the whole raising process , bacillus subtilis , yeasts and actinomycetes in deep-litter systems showed a decreasing trend ; and escherichia colis and molds revealed a rising tendency along with raising time .

数据表明，发酵床养殖圈棚能有效提高环境温度，地面温度，有利于寒冷季节养殖圈棚的保温，减少了养殖圈棚保温取暖的能源消耗。

Data shows , the pigpen with fermentation bed can effectively enhance the environment temperature and the temperature of the earth , it is good for heat prevention in cold season and can reduce the energy consumption . 2 .
