The carcass age at the slaughter of turkeys at the end of the monitored period was 109.3 days. The average live weight was 10.09 kg, the average daily gain was 89.5 g. The correlation coefficient between the age at the slaughter and the live weight in turkeys, r = 0.72, was statistically highly significant. The hybrid Converter turkeys reached 0.27 kg higher average live weight and 0.5 g higher average daily gain during the fattening period which was 1.5 days longer in comparison with the BIG hybrid turkeys. The average age of toms at the slaughter was 141.6 days with the average live weight 20.46 kg. The average daily gain was 142.1 g. The correlation coefficient between the age at the slaughter and live weight of toms, r = 0,29, was low, statistically probable significant. The BIG hybrid toms during the 4 days longer fattening period (p < 0,05) reached 0.5 kg (p < 0,05) higher average live weight compared to the Converter hybrid. There was only a slight difference in the average daily gain at both hybrids (142.0 g at the hybrid BIG, 142.1 g at the hybrid Converter). Both hybrids BIG and Converter showed almost the same feed conversion ratio. The hybrid BIG (8.43 %) recorded nearly 2% lower mortality than at the Converter hybrid (10.38%).
