This paper presents the results of empirical research on high quality beef production on the basis of the Cooperative "Agrofirm" Witkowo (Stargard Szczeciński poviat) and the individual farm Wyszobór. The research had been conducted on young crossbreed beef bulls with different genotypes in relatively intensive feeding conditions. The aim of the paper was the cost calculation of fodders per 1 kg gain in body weight in different raising systems. The first experiment consisted of young bulls genetically mixed of two or three races between Black-and-White x Red Angus crossed cows and Limousin meat breed bulls- (group I), Red Angus (group II) and Salers (group III). The second experiment consisted of young bulls from, group I - Charolais cows with Charolais bulls, group II - Hereford cows with Charolais bulls and group III - Simmental cows with Charolais bulls. In both cases young bulls from all the groups had a very good daily gain. A lower cost of fattening was noticed for the animals from experiment no. 2, where the animals had been raised in a pasture system with cow-mothers and had been better prepared for fattening.
