The nutritional effects of using decorticated sunflower meal (44 % protein) as the protein supplement in the laying hens feed mixture on egg production were investigated. The trial was performed on 75 laying hens (line hybrid Issa brown) during the first 150 days of lay. The hens were divided in five groups. The control group (C) was fed on a commercial complete feed mixture (corn-soybean meal and fish meal). The experimental feed mixtures contained sunflower meal (E1), sunflower meal with correction of energy value by addition of sunflower oil (E2), sunflower meal with correction of lysine (E3) and sunflower meal with correction of energy value and lysine (E4). The highest egg production was found in groups E3 and E4. The lowest consumption of feed was established in group E1, while the highest consumption was found in groups E3 and C. The highest increase in body mass was achieved in group E4. The deficiency of lysine in sunflower meal (E1) contributed to lower body mass, feed consumption and egg mass. Feed mixtures containing sunflower meal as the protein supplement (all experimental groups) had no influence on the health or mortality of laying hens.
