Fertile eggs from Large White turkey hens were classified according to weight at time of incubation. Glycogen was measured in the 21-day-old embryo and one-day-old poult. Liver glycogen was positively correlated with initial egg weight in the 21-day-old embryo and negatively related to initial egg weight in the one-day-old poult. Glycogen recycling was evident in the one-day-old poult. Maximum accumulation of 14C-glucose as glycogen occurred 60 min post injection. Liver phosphorylase a level was higher in the one-day-old poult than the embryo. Total phosphorylase per gram of liver tissue was not different between the two age groups. Liver phosphorylase b was subject to conversion to phosphorylase a in both age groups. Avian phosphorylase exists in both the active and inactive form.
来自大白火鸡母鸡的受精蛋在孵化时按重量分类。在21日龄胚胎和1日龄雏禽中测量糖原。21日龄胚胎的肝脏糖原与初始蛋重呈正相关，而1日龄雏禽的肝脏糖原与初始蛋重呈负相关。糖原循环在1日龄雏禽中很明显。注射后60分钟，作为糖原的14C-葡萄糖积累量达到最大。1日龄雏禽肝脏磷酸化酶a水平高于胚胎。两个年龄组每克肝脏组织中的总磷酸化酶没有差异。两个年龄组的肝脏磷酸化酶b都可转化为磷酸化酶a。禽类磷酸化酶以活性和非活性两种形式存在。
