abstract The effect of low-protein feeding mixture on the technological properties of the egg shell was studied and compared with commercial mixture. On the basis of obtained results it is possible to state that the suggested composition of the low-protein feeding mixture for layers allows to reach the level and egg qua-lity. All it is comparable with using of convention feeding mixture which is more costly due to the higher content of expensive protein components.
