摘　　要：采用放射免疫技术对１～２４月龄家牦牛、半血野牦牛血液中ＩＮＳ，ＧＨ，ＬＨ，Ｔ，Ｐ，１７β－Ｅ＿２含量进行研究。结果表明，家牦牛、半血野牦牛ＩＮＳ均值分别为３．０８２７±１．９５５１μＵ／ｍｌ，３．１４２４±１．４６６８μＵ／ｍｌ；ＧＨ分别为３．５５４９±０．４６２４ｎｇ／ｍｌ，３．９０４８±０．６０４７ｎｇ／ｍｌ；ＬＨ分别为０．３８２２±０．００２１ｎｇ／ｍｌ，０．４０８６±０．０６４９ｎｇ／ｍｌ；Ｔ分别为５．５６２１±２．５９２７ｎｇ／ｍｌ，１１．０４３７±１０．９５０８ｎｇ／ｍｌ；Ｐ＿４分别为０．５７２９±０．５０３６ｎｇ／ｍｌ，０．３５３９±０．２０３３ｎｇ／ｍｌ；１７β－Ｅ＿２分别为２６．３５３８±１５．６４６４ｐｇ／ｍｌ，２２．７０２１±６．９４７２ｐｇ／ｍｌ。经二因子无重复观察值的方差分析表明，家牦牛和半血野牦牛之间，各月龄之间ＩＮＳ，ＧＨ，ＬＨ，Ｔ，Ｐ＿４，１７β－Ｅ＿２含量均无显著差异。The insulin(INS), growth hormone (GH) , Luteinizing hormone(LH) , testos-terone(T),progesterone(P_4)and 17β-E_2 in the blood of domestic and semiwild yaks aged 1～24 monthes were measured with RIA method. The INS of domestic and semiwild vak were3. 082 7±1.955 1 and 3. 142 4±1.466 8μU/ml resp. Corresponding mean values for GH were3.554 9±0.462 4 and 3.904 8±0. 604 7ng/ml,fOr LH were 0. 382 2±0. 002 1 and 0.408 6±0.064 9ng/ml,for T were 5. 562 1±2.592 7 and 11. 043 7±10. 950 8ng/ml,for P_4 were0. 572 9±0. 503 6 and 0. 353 9±0. 203 3ng/ml and for 17β-E_2 were 26. 353 8±15. 646 4 and22. 702 1±6.947 2pg/ml,No difference was found between domestic and semiwild yaks andbetween ages.
