Abstract

The biochemical indexes “glycogen in liver” and “ketones in blood” of 0-72 hours feed deprived (according to methods for balanced experiments) Japanese quails with and without energy additives were determined. There were 2 groups of birds- 1-st without energy supplement, 2-nd- fed with 1 g. glucose per os (as 25% solution) – twice in 24 hours. The levels of liver glycogen in all the food-deprived quails were signifi cantly lower from -6910 (12-th hour of starving)-to 4960mg/kg (72 hour of starving) compared to the levels of the same index in fed birds (11990 mg/kg tissue). In the birds receiving energy additive they were higher compared to those deprived of the additive throughout the experimental period. The content of ketones in blood of the control birds was 0.015 mmol/l. The same index increased to 0.027 mmol/l in the feed and energy additive deprived group after the 36 hour of starving, but in the group became energy support, the contents of ketones were lower for the whole period of starving. The energy additive (1g glucose/24 hours) helped the maintenance of the energy metabolism during continuous food depriving of the experimental quails.
