| 摘 要： | 选用60只成年羯羊，分别以：围栏草地；非围栏草地自然放牧 250g尿素颗粒料；非围栏草地自然放牧 埋植增肉剂三种方法进行40d育肥。结果试1、试2和试3组每只羊平均增重分别比对照的非围栏自然放牧组提高4．41kg，5．41kg和3．51kg，日增重平均分别提高110g，135g和88g与对照组比较差异均显著(P＜0．05)。试1、试2和试3组每只羊分别比对照组多增收33元、25．2元和23．25元，总增收1221．75元。结果表明，在高寒牧区草地畜牧业生产条件下，无论采取围栏草地放牧，非围栏草地放牧 补饲或非围栏草地 埋植增肉剂育肥都能提高增重，且效果明显。

| Abstract: | mature wethers were used to conduct the fattening test by tree methods for 40d.The wethers in the test group 1 were factened in enclosed pasture.The one in the test groups 2 and 3 were fattened in natural grazing at the same time fed 250g urea pelletized feed and implanted the meat-increased agent, respectively.The wethers in control group were grazed in natural pasture.The results showed that the average liveweight gain of wethers in the test groups 1,2 and 3 was increased by 4.4kg,5.4kg and 3.5kg,the average daily gain was increased by 110g,135g and 88g,the in come from each sheep was raised by 33.00,25.20and 23.25yuan,respectively in comparison with that in control group.The total in come was inereased by 1221.75 yuan.It was suggested that tree fattening methods used in this test had all the effect of significantly increasing liveweight gain (P<0.05) under the productive condition of grazing in alpine-cold meadow. |
