高原型藏绵羊春季补饲试验
【目的】研究旨在探讨补饲对减少冷季掉膘的作用。【方法】在西藏当雄选择年龄为4.5周岁(2胎)的泌乳期母羊、8-12月龄后备母羊,分别进行60、90 d的补饲试验。【结果】结果表明,泌乳母羊试验组增重0.61 kg,而泌乳母羊对照组活重损失4.94kg,两者之间存在极显著差异(P〈0.01),补饲组间差异不显著(P〈0.05);后备母羊试验组增重6.44 kg,而后备母羊对照组活重损失1.3 kg,两者之间存在极显著差异(P〈0.01),补饲组间差异不显著(P〈0.05)。【结论】在青藏高原高寒草地,春季牧草青黄不接、自然放牧绵羊普遍掉膘的情况下,通过补饲精料可以有效提高增重、减轻载畜压力,获得...

Summary: | 【目的】研究旨在探讨补饲对减少冷季掉膘的作用。【方法】在西藏当雄选择年龄为4.5周岁(2胎)的泌乳期母羊、8-12月龄后备母羊,分别进行60、90 d的补饲试验。【结果】结果表明,泌乳母羊试验组增重0.61 kg,而泌乳母羊对照组活重损失4.94kg,两者之间存在极显著差异(P〈0.01),补饲组间差异不显著(P〈0.05);后备母羊试验组增重6.44 kg,而后备母羊对照组活重损失1.3 kg,两者之间存在极显著差异(P〈0.01),补饲组间差异不显著(P〈0.05)。【结论】在青藏高原高寒草地,春季牧草青黄不接、自然放牧绵羊普遍掉膘的情况下,通过补饲精料可以有效提高增重、减轻载畜压力,获得良好的经济效益。 |

[ Method ] The lactating ewes of 4.5 years (2 tires) and reserve ewes of 8-12 months in Damxung were selected as tested materials, and the feeding trials of 60, 90 days were conducted, respectively. [ Result] The experimental lactating ewe weighted 0.61 kg, while the lactating ewe in control group reduced g. 94 kg, there were a significant difference between them (P 〈0.01 ), and not significant difference between the feedin |
