Slow growing chickens of genotype Redbro, were reared in two systems in order to determine the effect of duration of fattening on values of slaughter yields/dressing percetages and shares of main carcass parts. Fattening of chickens in chicken coop to age of 84 days had considerable effect on increase of slaughter yields: conventional processing (83.59%), ready to roast (77.22%), ready to grill (67.17%) compared to 42nd day of age (82.21, 74.87 and 65.42%). Redbro chickens reared on free range had lower body masses compared to chickens reared to chicken coop in all investigated ages. Beside significant increase of body mass, longer fattening period influenced considerably decrease of share of back, pelvic and wings. In both rearing systems, prolonging of fattening had statistically significant effect on increase of share of abdominal fat.
