The results of the studying of active yeasts Saccharomy cescerevisiae influence on the egg-laying capacity and morphological characteristics of the hens "NOVOgen brown" breed eggs are presented. The nutritional intervention of active yeast Saccharomy cescerevisiae in laying hens diet allowed to increase egg-laying capacity by 3.7-6.6% and improve the morphological composition of the eggs. However, feed conversion in experimental groups was by 5.1-7.9% lower in relation to the control group.
