Artificial insemination technology is an important and practical fast technology for cattle breed improvement. It can not only give full play to the utilization rate of excellent breeding bulls, but also save a lot of investment in purchasing breeding bulls. Dairy cows bred through AI will produce calves with good genetic quality according to the preferences and choices of producers. In addition, artificially inseminated cows calve more prematurely, resulting in an increase in calving interval and weaning weight of cows. Therefore, they are popular with many farmers.
