By investigation of fattening characteristics of crosses obtained by crossing Simmental cows with the bulls of French beef breeds (Charolais, Limousine and Blonde d'Aquitaine) and Simmental controls, the following conclusions may be inferred. Using crossing dual purpose type of cattle with the beef breeds has given favourable results, because the crosses achieved considerably better results during the rearing period, as well as in the fattening period. With respect to slaughter quality, better results were achieved also in crosses than in control group. The crosses with Blonde d'Aquitaine breed achieved the highest average daily live weight gain of 1265 g and the highest dressing percentage of warm and cold carcasses, which amounted 65.58 and 63.23 per cent, respectively. In heifers, crosses with the same breed, the live weight gain of 1050 g was the lowest one, but the dressing percentage was the highest, amounting 64.11 and 62.39 per cent, respectively. The highest amount of muscle tissue was found in crosses with Limousin breed, on average 78.96 per cent, while the crosses with Charolais breed had the lowest share of muscle tissue, 75.61 per cent. In order to grade and rank the genotypes more properly according to their quality, further investigations should be carried out using larger number of animals in each group. By doing so, a more precise answer could be obtained, with respect to use of individual beef breeds for crossing with dual purpose cows in our populations of cattle.
