After fasting for 18, 24, 48 and 72 hours, blood glucose, lactic acid in the blood, liver glycogen, muscle glycogen, body temperature, and body weight were determined in singlecombed White Leghorn male chickens allowed to drink water ad libitum.
Blood glucose decreased slowly during the first 48 hours, increased thereafter, and returned to almost normal level at 72 hours. The decrease at 24 hours was statistically significant (P<0.01).
Liver glycogen decreased significantly at 18, 24, and 48 hours, but increased slowly thereafter. Muscle glycogen was not so much changed, showing a slight decrease at 24 hours. Lactic acid in the blood was influenced little by fasting throughout its entire duration. While fasting continued, the body temperature of the chicken decreased progressively in association with the decrease of body weight.
Trichloroacetic-acid-extractable glycogen was found to be 74 and 39 per cent of the total glycogen of the liver and the muscle, respectively, in intact chickens. It was expected to be related to the characteristic change of carbohydrate observed in this experiment.
