The objective was to investigate the effect of different hen genotypes on morphological and technological parameters of eggs. Investigations involved three han breeds - Red Rhode-Island (RIR), New Hampshire (NH), Light Sussex (SU), and three strains SLOVGAL - (03 A), (05 A), (06 A) kept as gene pools. Egg analyses were made in the 2nd, 5th and 8th month of laying period. Changes in the parameters of egg and its components - albumen, yolk, eggshell were confirmed, related to hen age and laying intensity. SU breed and Slovgal 06A strain had the lowest egg weights (55.12 g and 59.69 g, respectively.) No substantial differences were observed in specific weight and egg shape between the groups. New Hampshire (NH) hens had albumen of best quality. Yolk quality was better in Slovgal strains, yolk color values were lowest in RIR. Higher values of eggshell quality parameters were determined for Slovgal lines and NH breed.
