摘要
研究冬季发酵床养猪模式对猪舍环境、猪生产性能及免疫性能的影响。试验选用60头三元杂交断奶仔猪,分为两个处理,每处理5个重复,每重复6头猪。对照组为传统的水泥地面猪舍养殖模式,试验日粮为基础日粮+10%杆菌肽锌20mg/kg与10%硫酸粘杆菌素20mg/kg;试验组为发酵床猪舍养殖,试验日粮为基础日粮+0.1%日本酵素。测试指标为猪舍温度、相对湿度、悬浮颗粒浓度、氨气浓度、猪料肉比、平均日增重及血清IgAI、gM、IgG浓度。试验时间106d。结果显示,与对照组相比,试验组显著提高了猪舍温度(P<0.05),极显著降低了猪舍氨气和悬浮颗粒浓度(P<0.01),对猪舍相对湿度无显著影响;试验组显著提高了平均日增重、饲料转化率及血清IgAI、gG浓度(P<0.05),对血清IgM浓度无显著影响。试验表明冬季发酵床养猪模式可改善猪舍环境,提高猪的生产性能与免疫性能,优于水泥地面养殖模式。
The purpose of the paper was to study the offect of the Deep-Litter Sysytems on enviroment in swine house and swine productivity and immune function in cold seasons. A total of 60 crossed piglets were alloted to two treatments and 5 replications in each treatment and 6 swines in each replications. The control group was reared in traditional conxrete-based house and added 10% bacitracin zinc salt from bacillus 20mg/kg and 10% colistin sulfate 20mg/kg in basal ration. The treatment group was reared in deep-litter house and added 0. 1% micro-ecological agent from Japan. The testing indices included temperature,relative humidity,ammonia and total suspended particle concentrations in swine house and swine average daily gain weight （ADG） , feed conversion and IgA, IgG, IgM concentrations in serum. The experiment lasted 106 days. Result showed that the air temperature of treatment group was significantly increased in swine house（ P〈0.05 ）, ammonia and total suspended particle concentrations in swine house were significantly lowered（P〈 0.01 ） and it had no effect on relative huimidity in swine house; significantly raised ADG, feed conversion and IgA, IgG concentrations in serum （ P 〈 0.05 ）and no effect on IgM concentration in serum as compared with control group. Conclusion：Deep-Litter Systems could improve enviroment in swine house and increase swine productivity and immune function, better than model reared in concrete-based house in cold seasons.
