The aim of the research was to obtain comparative indicators of the slaughtering and quantitative characteristics of the laying hens from different hybrid lines. For the examination were used hybrid lines from ISA Brown, for gaining eggs with brown shell, and DeKalb, for gaining eggs with white shell. The total number of examined individuals is 40, 20 of each hybrid line, with an average age of 84 weeks. After the slaughter, the measurements of each carcass were made and the participation of the basic parts in the mass of the clean carcass was determined. The dressing percentage of clean carcasses without internal organs and skin of hens from the hybrid line ISA Brown is 49.80%, while the dressing percentage of chicken from the hybrid line DeKalb is 46.80%. The average mass of chests (white meat with bone) is 234.65 g in ISA Brown, or 26.95% in the mass of the carcasses, while in the DeKalb hybrid line the average mass of the chest is 197.20 g with 26.86% participation in the mass of carcasses.
