【摘要】 利用秸秆和塑膜覆盖封闭敞开式羊舍,探讨在最冷时节育成羊增重和剪毛量的效果,研究畜舍结构,保温性能及舍内外气象生态因子变化规律,为设计标准化羊舍,提供科学依据。育成羊舍外围护保温防寒处理后,在最冷时期(12月,元月)可提高舍温45.74％和71.16％,体重增加18.52％和10.59％的剪毛量,差异极显著P<0.01)。更多还原

【Abstract】 The effect of the temperature improvement of animal houses covered with crop residues and plastic on body weight gain and wool yield of ewes was investigated during the coldest season (December and January ). The internal temperatures were increased by 45. 74 percent and 71. 16 percent with the two coverings respectively. Body weight and wool yield increased 18. 52,10. 59 percent respectively. The difference was significant (P<0.01).更多还原
