Abstract:In order to study the fattening performance of the first filial generation of Red Angus×Chinese Red Steppe cattle(AHF1), 18-month-old Chinese red Steppe(Control group) and AHF1(Treatment group) with similar body weight were selected randomly, and fattened to 36 months old in the same feeding situation. The fattening performance in 24, 30, 36 months old were measured, and the slaughter indexes and the meat quality indexes in 36 months old were evaluated. The results showed that body weight, chest circumference, dressing percentage, neat percentage and eye muscle area of treatment group were significantly higher than those of the control group in 24, 30,36 months old, and the shear force value was obviously lower than control group. In conclusion, crossing Chinese red Steppe cattle with Red Angus could improve the production performance and beef tenderness.
