[Effect of high temperatures in the housing on some indices of carbohydrate metabolism in layers].
Experiments were carried out with a total of 60 layers of the White Plymouth Rock breed at the age of one year, acclimiatized to a temperature of 15 degrees C and relative humidity of 60 per cent. The following temperature and moisture regimes were tested: I--20 degrees C and 70 per cent; II--24 degrees C and 70 per cent; III--28 degrees C and 50 per cent; and IV--33 degrees C and 50 per cent. The birds of the control group were raised at 15 degrees C and relative moisture capacity of the air of 60-70 per cent. At the 24th hour and by the end of the seventh 24-hour period temperature vales of more than 28 degrees C led to dependable activization of the glucose-6-phosphatase enzyme in the liver and lower concentration of blood glucose and liver glycogen.
