Groups of the Czech Pied (C) and Black-Pied (N) cattle breeds were housed in a mosaic pattern in a tie-stall cowshed with individual feeding for comperative fattening. Feed ration was determined so as to provide for daily weight gain of 1,200 g. Fattening performance and indicators of carcass and technological analyses were evaluated, as well as some characteristics of meat quality in a sample of MLD. The bulls reached the average daily weight gains of 1.354 and 1.296 kg, resp., during this fattening. The bulls were slaughtered at the average age of 478.17 and/or 475.93 days while their weight was 525.05 and 516.69 kg, resp. The difference in slaughter weight between the groups (8.37 kg in favor of C bulls) was statistically significant. The level of weight gains in C bulls indicates good feed conversion and the ability of bulls continue effective fattening to higher slaughter weights. Included slaughter weight (coef. 1.8) (545.88 vs 520.62 kg) increased by 20.8 and/or 3.9 kg; the difference of 25.3 kg between the groups was statistically significant. Body measures showed sifnificant differences at both measurements in favour of N bulls. There were significant differences between the two genotypes in meat production per 1 kg bones and in meat yield out of the converted weight in favour of C bulls.
