Some factors affecting synchronization results in dairy cattle
Absztrakt
Estrus synchronisation in high yielding dairy cows is becoming an increasingly important
aspect of reproductive management in the dairy industry, showing results of improved
fertility and reproductive efficiency. Therefore, we wanted to study these effects and changes
in reproduction of the Double-Ovsynch protocol in a large number of animals over three
years. Our research took place at two large-scale dairy farms in Hungary with a total of more
than 2,542 Holstein-Friesian dairy cows included in the study, recording the data of both
reproduction and milk production parameters, before analysing the results.
