摘要: 微生物发酵床菜猪大栏养殖猪舍占地面积2 100m2, 养猪发酵床面积1 90 0m2, 利用率91.4%, 比传统猪舍包括隔离带的建设占地面积利用率46%提高45个百分点。猪舍四周设有喂食槽, 饮水槽设置在发酵床的中央分割线上和短边喂食槽的中部, 实现料水的干湿分离。猪舍长边的两侧设置有电动铝合金卷帘, 用于控制通气、降温和保温;短边的两侧分别设置有风机和湿帘, 屋顶外安装有喷雾降温装置, 用于猪舍内的降温。猪舍的环境控制, 包括光、温、水、湿、二氧化碳、氨气实现自动化。利用椰糠和谷壳配置的发酵床垫料养猪, 实现无臭味、零排放、肉质优、省人工、控猪病、无药残、产肥料、智能化、机械化。Abstract: In this study, the large-scale pig house was with an area of 2 100m2, covered by 1 900m2 fermentation bed, the utilization rate of which was 91.4%, 45% higher than traditional piggery construction.Feeding troughs were equipped around the piggery, and the water trough was set in the middle of the fermentation bed and short feeding trough, which made the forage separated from the water.The piggery was equipped with an electric aluminum alloy shutter in both long sides controlled by computer to regulate the ventilation, cooling and heat preservation.Both short sides were respectively equipped with fans and wet curtains.The spray cooling devices were installed outside the roof as an air condition in piggery.Piggery environment, including light, temperature, water, humidity, carbon dioxide and ammonia, was automatically controlled by computer.Using coconut chaff and chaff as the mattress of fermentation bed to raise pig was with no smell, zero emissions, high meat quality, less labor, disease control, no drug residues, fertilizer production, intelligent control, and mechanization operation.
