Cattle are many domesticated animals in the order Artiodactyla, family Oxidae, and genus Ox. The ancestor of this social animal is the primitive cow, which was domesticated and raised by humans about 8000 years ago. The production performance of large adult bull breeds is related to the economic benefits of the entire beef cattle breeding farm, and is an important factor affecting the genetic quality of cattle herds, as well as the foundation for cattle improvement. The purpose of raising breeding bulls is to provide a large and high-quality semen, and then stably inherit excellent genetic traits. Therefore, it is necessary to do a good job in the breeding of bulls, strengthen management, make reasonable use, and improve production performance.
