Abstract:In this test, the birth weight of Angus hybrid calves was 32.25 kg, 121.15 kg at 3 months, 183.75 kg at 6 months, 247.46 kg at 12 months, and 402.93 kg at 24 months, respectively, compared with other breeds of cattle in the same period. An increase of 20.34%, 141.33%, 90.16%, 26.07% and 41.38%, the difference was extremely significant (P < 0.01). A total of 4,307 Angus beef cattle had been promoted in the county for breeding with frozen semen, and 3,928 of them have been conceived, with a conception rate of 91.2%.
