摘要
为提高青海高原型藏羊选育工作，探索羊的人工采精和细管冻精技术在高寒地区的应用效果，对青海省海北州祁连3只高原型藏种公羊和玛多县30只高原型藏莞母羊进行了选育试验，实验结果表明：藏种公羊鲜精采集量平均为1．5mL，呈乳白或乳黄色、无气味、有云雾状，平均活力冻前鲜精为0．65，高出一般羊精子标准活力的0．075，冻后为0．35～O．5，高出本省羊精子标准活力O．1，且经冷配后的30只藏母羊均无返情现象。本实验对于藏羊的改良有重要的实践意义，对于改善纯种高原型藏羊也有重要的参考价值。
To improve the breeding of Qinghai plateau Tibetan sheep , exploring the application effect of artificial insemination and tube frozen semen technology in Alpine area, 3 plateau type of Tibetan rams from Qilian county and 30 plateau type of Tibetan ewes from Maduo county were selected for breeding experiment. The experimental results showed that fresh semen collection of ram was an average of 1.5 ml, a milky white or milky yellow, no smell, cloud - like, average vitality of fresh frozen semen was 0.65, 0.075 higher than general standard of sheep sperm vitality. O. 35 ~ O. 5 of frozen semen . 0.1 higher than Qinghai semen, and30 Tibetan ewes did not estrus. This experiment has important practical significance for the improvement of Tibetan sheep
