中国首次批量克隆六只高产奶山羊

中国研究人员首次成功克隆六只高产奶山羊,这些山羊于周一在陕西省实验设施出生,目前状况良好。

这些克隆山羊来自西北农林科技大学的研究团队及其合作伙伴。他们使用基因组选择和体细胞克隆技术,供体为萨能奶山羊,日产奶量超过8公斤。

研究团队负责人王小龙表示,克隆山羊包括四只雄性和两只雌性。供体山羊年产奶量超过2800公斤,乳脂和蛋白质含量高于平均水平。

中国动物农业协会羊业分会负责人杜立新指出,与传统方法相比,该技术可显著缩短育种周期,后者通常需要八到十年才能培育出改良种群。

陕西省拥有中国40%的奶山羊,并加工80%的山羊奶制品。该突破有助于快速扩大优质畜牧遗传资源。
