Abstract

Heritability of plasma alkaline phosphatase and 5'-nucleotidase enzyme activities at 20, 35 and 50 weeks of age ranged from 0.047 to 0.275. Genetic and phenotypic correlations among enzyme activities at the three ages were positive and high. Genetic correlations of enzyme activities with production traits indicated that the bird having higher activities of these enzyme will grow faster, mature earlier and produce heavier but fewer eggs.

摘要

20周、35周和50周龄时血浆碱性磷酸酶和5'-核苷酸酶活性的遗传力范围为0.047至0.275。三个年龄段酶活性之间的遗传和表型相关性为正且较高。酶活性与生产性状的遗传相关性表明,这些酶活性较高的禽类生长更快、成熟更早,产蛋重但数量少。
