【摘要】 缙云麻鸭原产浙江省缙云县一带,是我国著名的蛋鸭高产品种。按开产体重把缙云麻鸭分为5组,比较各组鸭的产蛋性能。结果表明:缙云麻鸭开产体重在1200~1500g范围内300d总蛋重和300d总蛋数均较大,但不同开产体重对平均蛋重的影响不大。更多还原

【Abstract】 Jinyun County,Zhejiang Province is the provenance of Jinyun ducks,which is a highly productive breed.In this research,Jinyun ducks were divided into 5 groups,based on their close-on-production weight.The egg-production performances of the groups were compared with each other.The result indicates that the ducks whose close-on-production weight ranges from 1200 to 1500g all have comparatively better egg-production performance in terms of both the total number as well as the total weight of the eggs they produced during a period of 300 days.However,no significant correlation is indicated between their close-on-production weight and the average weight of the eggs they produced.更多还原
