Currently, the improvement and modification of more effective programs for synchronizing sexual hunting in cows is one of the urgent issues in agricultural and veterinary science. This paper presents the results of a comparative evaluation of the effectiveness of the developed method of synchronization of sexual hunting in comparison with the Ovsynch-48 synchronization program in the conditions of a modern high-tech enterprise for the production of milk using robotic milking "Donskoe" in the Volgograd region. The article indicates a new scheme for synchronizing sexual hunting in cows using, in addition to GnRH and PGF preparations, as well as preparations containing vitamins A, E and selenium. It was found that the percentage of the first insemination with the developed method of synchronization of sexual hunting in highly productive cows is 17.5% higher compared to the Ovsynch-48 synchronization scheme. |
