The objective of the present study was to transpose sperm freezing methodology from domestic goat to the Tadjik markhor () and to address the feasibility to develop IVP and artificial insemination using such frozen semen. Semen of different adult markhor males were successfully recovered by electro-ejaculation and were then frozen using caprine methodology. Frozen semen showed good survival rates at thawing and good fertility rates were assessed in heterologous fertilization system with goat oocytes. LOPU/IVF was applied for Tadjik markhor females allowing the first successful blastocyst production . In an applied program, we also transposed successfully intrauterine AI method with frozen/thawed semen to the Tadjik markhor.
本研究的目的是将家山羊的精子冷冻方法应用于塔吉克盘羊,并探讨使用这种冷冻精液开发体外受精(IVP)和人工授精的可行性。通过电刺激采精成功采集了不同成年盘羊雄性的精液,然后采用山羊的方法进行冷冻。冷冻精液解冻后显示出良好的存活率,并且在与山羊卵母细胞的异种受精系统中评估了良好的受精率。对塔吉克盘羊雌性应用腹腔镜采卵/体外受精(LOPU/IVF)技术,首次成功获得了囊胚。在一个应用项目中,我们还成功地将冷冻/解冻精液的子宫内人工授精方法应用于塔吉克盘羊。
