Abstract

Abstract: Small Tailed Han Sheep and F1 of Poll Dorset and Small Tailed Han Shee
p in different month age were selected randomly to make comparison between their growth performances. The result showed, under the same feeding condition, the birth body height of F1 sheep is obviously higher than Small Tailed Han Sheep by 14.49%（P＜0.01）;The body weight, body height, body length and chest girth of F1 sheep are dominantly higher than Small Tailed Han Sheep at the fourth month after birth respectively by 9.26%，12.81%，10.68%，9.77%（P＜0.01）;As to the 6-month-age sheep,the body weight of F1 sheep is higher than Small Tailed Han sheep by 23.11%（P＜0.01）,and average daily gain of F1 sheep is higher than Small Tai
led Han Sheep by 44.41%,while there is no obvious difference in body measurements between them.

Key words: poll dorset sheep; small tailed han sheep; crossing; production performance
