Abstract
The application provides a method for improving the efficiency of timed insemination of dairy cows under summer conditions, which improves the efficiency of timed insemination of dairy cows under summer conditions by applying at least three of the following means to the cows; the means include: injection of GnRH, injection of PG, injection of eCG, injection of hCG, injection of ketoprofen, injection of A3, and embedding CIDR. Experiments show that the use of CIDR, eCG, hCG, ketoprofen and the like significantly improves the efficiency of timed insemination of dairy cows under heat stress conditions, thereby improving the fecundity of dairy cows under summer conditions, and has important economic value and social value for guaranteeing the healthy development of the dairy farming industry.
