Abstract. When dairy cattle production predominates, the quantity and quality of beef can be increased through commercial crossing of beef bulls with dairy cows and creating herds for the purpose of beef production. This experiment was conducted to compare carcass traits in young bulls and steers, produced by crossing Holstein-Friesian (HF) cows with Hereford (HH) bulls and slaughtered at 15 and 18 months of age. One half of 32 young bulls were castrated at 2 or 3 weeks of age. Starting at 7 months of age, they received grass silage supplemented with concentrates. At the end of the fattening period, the animals were slaughtered, carcass quality and the quality of meat from m. longissimus thoracis were evaluated. It was found that unlike steers, bulls can be slaughtered at a later age because their carcass traits improved over time and carcass fat content increased only insignificantly. Meat from steers had higher intramuscular fat content (1.20 and 2.35% in bulls and steers slaughtered at 15 months of age, respectively; 1.89 and 3.79% in bulls and steers slaughtered at 18 months of age, respectively), it was tenderer and juicier than meat from bulls, and its sensory quality improved with age. The intramuscular fat (IMF) of steers was characterized by a more desirable n-6n-3 polyunsaturated fatty acid (PUFA) ratio, whereas the IMF of bulls had higher concentrations of conjugated linoleic acid and n-3 PUFAs. Beef from steers is a good choice for consumers who appreciate high-quality meat. The results of this study may encourage producers to raise steers for beef.

Short summary
The quantity and quality of beef can be increased through crossing beef bulls with dairy cows. This experiment was conducted to compare carcass traits in young bulls and steers, produced by crossing Holstein-Friesian cows with Hereford bulls. Meat from steers had higher intramuscular fat content and was tenderer and juicier than meat from bulls. Steer IMF was characterized by a more desirable n-6 / n-3 PUFA ratio. Beef from steers is a good choice for consumers who appreciate high-quality meat.
