[Effect of the lighting intensity on carbohydrate metabolic indices in broilers].
Studies were carried out to establish the effect of light of various intensity on some of the indexes of the carbohydrate metabolism. The changes were followed up in the content of liver and muscle glycogen, and the amount of pyruvate was determined in the blood of the birds along with the activity of the glucose-6-phosphatase and succinate dehydvatase enzymes in the liver. No statistically significant changes in the liver glycogen were established under the effect of the illumination regime. A higher amount of muscle glycogen was found in birds raised at lower illumination intensity. This was better manifested in birds at the age of 45 days. The lower intensity of light was also associated with certain drop in the activity of the liver enzymes. There was likewise a lower concentration of blood pyruvate in birds kept at lower intensity of illumination.
