羊穿衣对青海毛肉兼用细毛羊生产性能的影响

Studies on Effects of Sheep Overclothes on Production Performance of Qinghai Fine-wool Sheep

从青海毛肉兼用细毛羊群中,随机选择1岁母羊一群(210只)、2岁母羊一群(220)只,进行了羊穿衣对比试验。结果表明:试验组除污毛量比对照组分别低9.6%和7.6%外,羊毛长度试验组比对照组分别提高了8.47%和3.95%,差异显著(P<0.05);羊毛油汗长度试验组比对照组分别提高了46.6%和37.7%,差异极显著(P<0.01);毛丛污染长度,试验组比对照组分别降低了41.0%和37.3%,差异极显著(P<0.01);净毛量试验组比对照组分别提高了14.5%和15.4,差异极极显著(P<0.01);净毛率试验组比对照组分别提高了26.9%和25.2%,差异极显著(P<0.01)。

1 year old 210 Qinghai Fine-wool Sheep and 2 years old 220 Qinghai Fine-wool Sheep Were divided two groups, the sheep of treatment group were worn sheep overclothes and no any treatment for control group. The results shows that the greasy weight of treatment groups were lower 9.6%, 7.6% than that of control groups, wool length of treatment groups were higher 8.47% ,3.95% than that of control groups and the difference is significant（P〈0.05）. Wool grease of treatment groups were higher 46.6%, 37.7% than that of control groups, the difference is significant （P〈0.01）. Polluted depth of treatment groups were lower 41.0%, 37.3% than that of control groups, the difference is significant （P〈0.01）. Clean-fleece weight of treatment groups were higher 14.5%, 15.4% than that of control groups, the difference is significant （P〈0.01）. Cleanfleece rate of treatment groups were higher 26.9% ,25.2% than that of control groups and the difference is very significant.（P〈0.01） .
