Anotace: The objective of this study was to compare the pure chicken breeds Oravka (OR; n = 50), Amrock (AM; n = 50) and their cross Oravka×Amrock (ORAM; n = 50) and Amrock×Oravka (AMOR; n = 50) for productive and carcass parameters. The birds were maintained on a deep litter system for a period of 20 weeks. We recorded that crossbred ORAM and AMOR chickens performed better than the average of parental genotypes for body weight and body weight gain in brooding and growing period. The poor (P<0.05) feed conversion was observed in AM chickens and better feed conversion was recorded in OR and both crossbred chickens. The crossbred chickens had lowest (P<0.05) mortality than pure bred AM chickens. The carcass parts, giblets and abdominal fat percentages had non-significant (P>0.05) difference among pure and crossbred chickens. The highest carcass yield was observed in ORAM (62.53%) followed by AMOR (62.48%), AM (62.41%) and OR (62.39%) chickens.
