摘要
为了研究发酵床猪舍冬季饲养育肥猪效果,试验采用杜大长育肥猪180头,以水泥地面猪舍为对照,以猪舍温度、相对湿度、氨气浓度和平均日增重、料重比为判定指标。结果表明:与水泥地面猪舍相比,猪舍湿度、氨气浓度得到显著改善,日增重提高了7.5%。
To investigate the efficacy of Deep-Litter Systems on enviroment in growing pigs' productivity.A total of 180 crossed pig-lets were alloted to two treatments.The control group was reared in traditional concrete-based house.The testing indices included temperature,relative humidity,ammonia concentrations in swine house and average daily gain weight,feed conversion.The results showed that relative humidity and ammonia concentrations in swine house was extremely significantly lowered(P<0.01) and it had no effect on temperature in swine house;significantly raised average daily gain weight as compared with control group.
