冬季可拆迁式猪舍对生长育肥猪生长性能及舍内温湿度的影响

Effects of the Removable Pig House on Growth Performance of Growing-Finishing Pigs and Its Indoor Temperature and Humidity in Winter

试验通过可拆迁式猪舍与传统(固定)猪舍的饲养对比试验,研究了冬季可拆迁式猪舍对生长肥育猪的生长性能及舍内温度和相对湿度的影响。选取同期转群、体重30 kg左右杜大长生长猪216头,随机分成可拆迁式猪舍组和传统猪舍组,每组3个重复,每个重复36头。试验至猪体重达到100 kg左右出栏结束。结果表明:可拆迁式猪舍组试猪的平均日增重和平均日采食量分别比传统猪舍组提高17.28%(P<0.01)和12.13%(P<0.01),饲料料增重比降低7.00%(P<0.05);可拆迁式猪舍的舍内平均温度为20.33℃,比固定猪舍的16.86℃高3.47℃,比室外的15.15℃高5.18℃,差异均极显著(P<0.01)。试验结果表明,可拆迁式猪舍对生长育肥的生长性能和室内环境控制优于传统猪舍。

This experiment was conducted with 216 crossbred（Duroc×Landrace×Yorkshire） growing pigs to study the effects of the removable pig house（RPH） and the traditional fixed pig house（FPH） on the growth performance of growing-finishing pigs and their indoor temperature and relative humidity in the winter.According to completely block design,the pigs were randomly divided equally into 2 treatment groups RPH group and FPH group,each with 3 replications and 36 pigs in each repetition and received the same standard corn-bean diets included a grower from 30 kg to 60 kg in the average bodyweight and then a finisher until about 100 kg.The results showed that： RPH can increased the average daily gain and average daily feed intake were by 17.28%（P 0.01） and 12.13%（P 0.01）;material weight ratio reduced 7.00%（P 0.05）,on the average temperature,RPH was 20.33℃ higher than FPH′s and outdoor′s by 3.47℃,5.18℃（P 0.05）.It is clear that the growth performance of growing-finishing pigs and the indoor environment parameters in the removable pig house were significantly better than those in the ordinary pig house.
