碱性磷酸酶同工酶与产蛋性能的关系

Relationship Between the Isoenzyme of Alkaline Phosphatase and Egg Laying Performance

本文利用聚丙烯酰胺垂直板高压电泳分离了18周龄115只岩谷蛋鸡的血清碱性磷酸酶同工酶,其中快型35只,慢型80只,并就快慢两型的体重、血液中某些生化指标和产蛋性能进行比较。结果表明:快型同工酶的鸡,8周龄体重、血清碱性磷酸酶活力、开产蛋重、开产日龄、300日龄体重、300日龄蛋重,极显著的大于慢型鸡;而300日龄产蛋数极显著的低于慢型鸡。

115 hens aged 18 weeks were separated with vertical plate Electropharesis Using Polyaccrylamde gel as supporting material. Fast-type isoenzyme was isolated from the 35 of 115 hens, and slow-type from the rests. The results show that the body weight at the age of 8 weeks, activity of serum alkaline phosphatase, the weight of first egg> age at first egg,body weight and egg weight at 300-day-age of ten hens with fast -type isoenzymes were significantly higher than that of the hens with slow-type iso-enzymes. The total protein, albumin, total weight of egg and number of eggs of slow-type hens at 300-day-age and 504-day-age were significantly higher than that of the fast type hens.
