1、庄河大骨鸡保种方案庄河市大骨鸡繁育中心二OO六年一月二十五日庄河市大骨鸡保种方案前言庄河大骨鸡在2000年9月被农业部确定为国家级畜禽资源保护品种之一。庄河大骨鸡主产于庄河市，因其体大魁伟，胸深背宽，腿高胫粗，骨骼粗壮，产百克以上大蛋屡见不鲜，故名大骨鸡。其形成历史悠久，是我国优良的肉蛋兼用型地方鸡种；是国内独具特色的家禽类种质资源，是我国优良的十大名种之一，经中国科学院遗传研究所对其血型测定和群体遗传学分析，认为：从血型因子群体遗传构成上看，与内蒙古边鸡等地方鸡种遗传关系较远，遗传相似性较小，看不

2、出它们之间存在的密切的亲缘关系。可见庄河大骨鸡是极具保种价值的家禽遗传基因资源；根据庄河鸡这一地方品种的优良特点和遗传特性，明确近期和中远期保种目标，制定具体的保种方案和切实可行的措施，有着十分重要的意义。摘要庄河大骨鸡形成历史悠久，体大、蛋大、肉质极佳，是国内独具特色的家禽类种质资源，已被农业部确定为国家级畜禽资源保护品种之一。大骨鸡成年公鸡最大体重达6.5千克；大蛋70-90克屡见不鲜，最大蛋重105.5克、105.2克；庄河鸡肉、脂肪含量低于肉鸡15.5%，蛋白质高10.3%，铁含量高64.6

3、%，锌、铜、锰高于肉鸡30%以上。依据庄河大骨鸡的血型和性状遗传特点，风土驯化和营养管理因素对其形成的影响，大骨鸡的保种重点是使其体大、蛋大、肉质极佳的遗传基因在种群延续，不使其流失；并通过选育而纯化。保种方法采用场、群结合，即大骨鸡繁育中心建三个品系，每品系由20个家系组成，继代个体无亲缘关系，避免近亲繁殖。根据地域不同，规划6个乡镇保种区，在规化保种区内尽量保存大骨鸡的遗传多样性，使其现存基因不流失。到2010年品系繁育鸡达到基因纯合，遗传稳定。有计划的在庄河本市区内，普及推广大骨鸡，使其产业化
