The effect of non-protein energy source and age on the blood glucose level and the muscle glycogen content of young chicks.

Blood glucose levels and skeletal muscle glycogen concentrations were observed in 160 male chicks. Observations were made in four age groups and two diets. Carbohydrate diets resulted in higher blood glucose levels and glycogen concentrations than did fat diets. Age was found to significantly influence glycogen concentration in both diets. The linear regression of skeletal glycogen on blood glucose levels was significant in carbohydrate fed chicks.
