新华社北京12月12日电 题:“绝不让雪域高原濒危种质资源灭失”——西藏阿沛甲咂牛与樟木牛抢救性保种全面展开 新华社记者刘诗平 雪域高原珍贵的种质资源——西藏阿沛甲咂牛和樟木牛的体细胞12日成功移入国家家畜基因库进行战略保存,阿沛甲咂牛和樟木牛的体细胞保种取得重要进展。 阿沛甲咂牛和樟木牛是国家培育适应高原环境品种的战略资源,但目前其群体数量少,处于濒临灭绝状态。随着第三次全国畜禽遗传资源普查深入推进,抢救性保种工作全面展开。 2022年12月12日,全国畜牧总站、国家家畜基因库和中国农业大学、中国农业科学院北京畜牧兽医研究所的代表在国家家畜基因库举行阿沛甲咂牛、樟木牛体细胞入库交接。(国家家畜基因库供图) 数量不足百头,消失灭绝风险大 2021年初,农业农村部启动为期3年的第三次全国畜禽遗传资源普查,青藏高原畜禽遗传资源重点调查工作随之展开。根据2021年面上普查和2022年系统核查,阿沛甲咂牛仅存39头,集中在林芝市工布江达县仲莎乡比久村;樟木牛仅存19头,集中在日喀则市聂拉木县樟木镇帮村。 西藏工布江达县比久村的阿沛甲咂牛。新华社记者刘诗平摄 记者在仲莎乡比久村看到,阿沛甲咂牛体型不大,毛色以黑色或黑花为主,额部白色居多,母牛乳房比当地其他黄牛大。阿沛甲咂牛是在南亚瘤牛与本地黄牛杂交基础上选育形成的,非常适应本地环境。 “阿沛甲咂牛一直处于农牧户自繁自养状态,群体规模较小,因比久村没有进行黄牛改良工作,这个品种得以保留,但是退化严重,濒临灭绝。”林芝市农业农村局畜牧兽医站高级兽医师次仁说。 调研组向当地村民了解阿沛甲咂牛情况。新华社记者刘诗平摄…
