[Thermoregulation in chickens subjected to hypoalimentation].

Calculation of the body temperature of 4 chickens, 14 days old, submitted during 26 days to a reduced nourishment so that their growing up was stopped. Morning temperature diminished, in comparison with checkings, of 0,78 degrees in the first week, of 1,57 degrees in the second week and of 1,80 degrees in the last days. After 1 and 2 hours of reduced meal, the temperature generally increases 0,76 degrees and 1,39 degrees respectively when chickens are hypo-nourished, while in the checkins it is almost unchanged, +0,02 degrees and +0,07 degrees. 5 hours after the meal, the temperature of hypo-nourished chickens increases 0,24 degrees, in checkings 0,30 degrees. AA thinks that hypotalamic thermoregulating centers always work and that the thermic differences between hypo-nourished and checkings are caused by percentage variations of metabolic substances put in circulation during digestion.
