发酵床健康养猪工艺的研究与应用报告
Hubei Agricultural Sciences(2011)
Abstract
按照发酵床养猪工艺的要求建造猪舍,在猪舍发酵床铺设0.8 cm厚的有机垫料,在垫料和饲料中添加三种不同的微生物制剂,与传统养猪进行对比试验,试验仔猪初始重25kg左右,当同栏猪达90kg左右时试验结束.结果表明,采用发酵床养猪工艺较传统养猪可提高增重速度12.2%~14.5%,节约饲料消耗8.1%~10.8%;育肥猪养殖效益提高31.56%;猪群发育状况和健康状况显著改善,实现了高效健康养猪.猪只排粪量减少2.88%,猪粪中氨态氮及钙、磷含量分别减少49.57%、46.15%、27.97%,实现了减量排放.猪粪再通过垫料中微生物发酵降解,基本实现"零排放",不污染环境.但猪舍内小环境气候及环境卫生状况较差.
