摘要
本文对斜面式和垂直式塑料暖棚羊舍内环境与羊生产性能进行了对比分析。经t检验表明 ,两种羊舍内环境指标及成年羊和羔羊增重差异均极显著 (P <0 .0 1) ;产羔率差异显著 (P <0 .0 5 ) ,羔羊成活率及繁育率差异极显著 (P <0 .0 1)。两舍内气温相差 0 .3℃～ 2℃ ,其羊毛生长速度差异不显著 (P >0 .0 5 )。
The article has compared and analyzed environment and performance of sheep in plastic ceiling sheep house of sloping form and vertical form.There were great difference in environmental indexes(p<0.01),daily weight-gaining amount(p<0.01),reproductive rate(p<0.05),survival rate of lamb and productivity of lamb(p<0.01).The differece in wool growing ratio wasn't significant(p<0.05).
