Effects of Age, Sex and Line on Serum Alkaline Phosphatase of the Chicken.

Abstract

Serum alkaline phosphatase level was measured in White Leghorns at various intervals from hatching to 34 weeks of age. It was higher in most cases between 2 and 26 weeks of age in a line bred for high alkaline phosphatase than in a random bred control line. The level in the male was higher than the female during the growing period, but lower at later ages. There were no differences due to line or sex at hatching.
