摘　　要：针对传统猪舍污水产生量大、处理费用高问题,该文设计并建造了一种基于减少育肥猪生产过程中污水排放的猪舍,为了检验少污水排放猪舍的饲养和环境控制效果,以规模化猪场常规育肥猪舍为对照舍,对其春季和夏季的生产效果和环境效果进行了研究。结果表明:试验舍与对照舍夏季平均温度分别为26.6℃、27.0℃,相对湿度分别为77%、71%,春季平均温度分别为18.9℃、21.0℃,相对湿度分别为50%,49%,试验舍和对照舍内育肥猪的平均日增质量、料质量比基本相同;但少污水排放型猪舍具有明显的节水效果,单头猪夏季减少用水量13.2L/d,春季减少用水量1.4L/d,夏季减少污水量16.5L/d,春季减少污水量4.7L/d,,少污水排放型猪舍不影响育肥猪生长性能,但能较大的减少生产过程中的用水量和污水排放量。A hoop structure swine production system was designed aiming to reduce wastewater from pig production.A 100-head hoop structure for finishing pigs was built in Beijing,and the environment status and pig performance in the hoop structure were studied and compared with that of control in typical brick-concrete concentrated swine house. Results showed that the average inner air temperature in hoop structure and control house was 26.6℃,27℃,and relative humidity was 77%,71%,respectively,in summer;Average inner air temperature was 18.9℃,21℃,and relative humidity was 50%,49%,respectively,in spring;Pig’s daily average gain and feed grain ratio were no significantly different between the hoop structure and control house,but water-saving effect was very significant in the hoop structure,with water consumption in hoop decreased by 13.2 L/d each pig in summer and 1.4 L/d each pig in spring compared with control house,which reduced 16.5 L/d and 4.7 L/d waste water in summer and spring, respectively.
