[Weight increase in chickens subjected to hypoalimentation].

14 days old chickens receive during 26 days a reduced nourishing share so that their growing up is stopped. At the end of this hypo-nourishment their weight is generally corresponding to 25.2% of the weight of normal chickens. When the nourishment is again as much as they wish, they swallow every day more food than during checking of the same weight and the speed in growing up found out is higher both than during checkings when the weight was the same and than the one of the checkings when age was the same. Comparing the recovery speed between hypo-nourished chickens and chickens submitted to repeated periods of non-eating, recovery in weight in comparison with checkings reaches 80% approx., however recovery speed is much lower in hypo-nourished chickens. The reasons for this difference are discussed.
