近日，国内白羽肉鸡产业的种源供应再起波澜。由于法国主要供种地区爆发高致病性禽流感，国内祖代 种鸡引种工作被迫中断，行业龙头益生股份已确认暂停1月下旬两批引种计划。 此次事件中，国内自繁体系成为抵御外部冲击的关键缓冲。数据显示，2025年国内祖代种鸡自繁量达 90.72万套，占总更新量的59.07%，较2024年增长10.36%，首次占据市场主导地位。 其中，"广明2号"等国产品种逐步推广，在抗病性、适应性等方面展现优势，打破了国外品种长期垄断 的格局。 近年来，广东省农业科学院动物科学研究所（以下简称"研究所"）承担"优质快长型肉鸡基因组选育体 系建立与新品种培育"项目，针对肉鸡育种中存在的"卡脖子"问题，与中国农业科学院北京畜牧兽医研 究所等国内6家肉鸡育种优势单位联合开展科技攻关，成功培育出黄羽肉鸡"岭南黄鸡5号"和白羽肉 鸡"广明2号"两大新品种，并构建了新一代肉鸡生物育种技术体系。 一系列成效，标志着我国在肉鸡育种领域实现从跟跑到并跑的跨越发展。 育种从"引进来"到"走出去" 鸡肉是全国第二大消费肉类，主要为白羽肉鸡、黄羽肉鸡和小型白羽肉鸡三种。其中，白羽肉鸡产量占 比超七成，尤其在"无鸡不成宴"的广 ...
