In middle of Sep 2004, viz these lambs age of 8 months, have been slaughter test and production performance analyzed. Results indicated that S♂× K ♀ and S♂× H ♀ crossed offspring＇ s carcass weight higher than Kazakh sheep and Small Han-tail sheep pure breed offspring ＇ s 5. 72 kg, 4. 12 kg, and net mutton weight higher 4.81 kg,3, 86 kg,inereased weight marked hess（P〈0. 05）. But S♂×k ♀ offspring＇s carcass weight and net mutton weight higher than Small-Han-tail sheep pure breed offspring＇ s 12. 01 kg, 1 049 kg, increased weight terribly marked heSS（P〈0.01）.
