摘　　要：通过对非发情周期中不同生理状况高原型牦母牛在青草期和枯草期四种生殖激素水平的测定,发现空怀母牛、青年母牛的雌激素、孕酮、促黄体素的基础水平青草期高于枯草期。说明营养的供给影响雌激素、孕酮、促黄体素的基础水平。The level of four reproductive hormone of female yak of plateau type in anoestrous period and in differ physiological state were mensurated in glass growing period and glass withered period. The results showed that the basic level of estrogen,progesterone and luteinizing hormone of nonpregnaney female yak group and heifer yak group in glass growing period were more higher than that in glass withered period. This indicated the basic level of estrogen, progesterone and luteinizing hormone were effeeted by the nutrition supply.
