The end of last century,Mao Yong type to the meat sheep wool combinat iuon and development of the meat type,and the lack of special mutton sheep b reeds in our province,but has a huge group of small tail coldsheep,northeast fin e wool sheep group, and how to according to the modern animal genetic theor y, make full use of heterosis, produce high-quality hybrid goods mutton sheep,i s our province is the only way for the development of mutton sheep industriali zation in our country.Although our province since the late 1990 s, introduced DorPer sheep. Sout h beauty,and other special meat sheep varieties,also conducted a hybrid improv ed a lot of work with local varieties,but not always choose the suitable for loc al mutton sheep industrialization eventually hybrid combinations. So, this paper experimentally with foreign merino sheep, mutton sheep breeds South Africa Du Bo northeast fine wool sheep sheep and small tail han sheep, hybrid gener ation of the growth rate and of the lamb meat production performance,and co mparative analysis. Test random south, north and south, du cold cold F1 F1 f ormula one male female 30 above, under the condition of the same breeding b reeding, by measuring the growth of birth, 3, 6, 9 month speed index and 10 months of meat performance index, the study compared different combination h ybrid sheep production performance, so as to better provide basis for hybrid sh eep breeding excellent varieties. The results show that the use of merino sheep and small tail cold sheep cross, the hybrid generation in body growth and me at performance good heterosis. Proved by South African merino sheep and sma ll tail cold sheep hybridization is an effective way to improve the level of mut ton sheep production.
