【摘要】 通过对兴国灰鹅的血液生化指标与产蛋量及70日龄体重的相关性分析,确定血清碱性磷酸酶活性为兴国灰鹅产蛋量早期间接选择的遗传标记,血清白蛋白相对含量为兴国灰鹅70日龄体重间接选择的遗传标记,并应用于兴国灰鹅的育种实践中,取得了较好的选择效果,使兴国灰鹅的产蛋量提高10%,70日龄体重提高6.8%,证明应用生化遗传标记进行兴国灰鹅的早期间接选择是可行有效的。更多还原

【Abstract】 Analysis of Xingguo Grey Goose’ s blood biochemical indexes,egg production and 70-day-old weight showed that the genetic markers of early indirect selection is Serum Alkaline Phosphatase Actiuity,amd the genetic markers of 70-day-old weight is the relative content of serum albumin.Moreover,these markers were applied in Xingguo grey goose breeding,it achieved better choice effect in the practical application,and increased the laying rate and the 70-day-old weight by 10% and 6.8% respectively.This proved that it is feasible and effective for the early indirect selection using biochemical genetic markers.更多还原
