猪舍温度控制技术应用的研究

用不同的冬季采暖和夏季降温技术可获得不同的环境条件。该文分别就热风炉采暖、湿帘风机系统降温与火炉采暖自然通风降温的分娩舍、保育舍二种猪舍进行了对比试验。结果表明,试验舍的环境条件明显好于对照舍;试验舍哺乳仔猪断奶成活率冬季、夏季分别为96．37％和95．36％,比对照舍分别提高4．28和6．97％;冬季试验舍保育猪的平均育成率为98．09％,日增重0．409kg／(d·头),分别较对照舍提高5．27％和30．67％,料肉比为1．472:1,下降13．25％,而夏季湿帘风机系统对保育舍猪的生产性能没有明显影响。

Research on temperature control technique in pig barns

Using different technologies of winter heating and summer cooling system can obtain different environ- mental conditions.Is this paper the research had separately carried out in the experimental barns(including farro- wing barn and weaning barn)which were heated by heated air furnace and cooled by evaporative pad and fan sys- tem,and in the contrast barns which were heated by stove and cooled by natural ventilation.The experiment re- sults indicated that the environmental conditions of experimental barns were obviously better than than of the con- trast barns.In experimental barns,the average survival rate of the suckling pigs reached 96.37% in winter and 95.36% in summer,which were 4.28 and 6.97 percentage higher,respectively,than that of the contrast barns. And in experimental barns,the average survival rate of weaning pigs in winter reached 98.09% and the average daily gain reached 0.409 kg/d per pig,which were 5.27% and 30.67% higher,respectively,than the contrast barns;While the feed/meat ratio was 1.472:1,which was 13.25% lower.In summer,evaporative pad and fan system had no obvious influence on pig's production performance in weaning barn.
