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

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(P0.05).Wool grease of treatment groups were higher 46.6%、37.7%than that of control groups,the difference is significant(P0.01).Polluted depth of treatment groups were lower 41.0%、37.3%than that of control groups,the difference is significant(P0.01).Clean-fleece weight of treatment groups were higher 14.5%、15.4%than that of control groups,the difference is significant(P0.01).Cleanfleece rate of treatment groups were higher 26.9%、25.2%than that of control groups and the difference is very significant.(P0.01)
