Important differences exist between estrus synchronization and ovulation synchronization.
In the latest issue of the Georgia DairyFax Newsletter, Bradley Heins and Michael Overton with the University of Georgia College of Veterinary Medicine, discuss the differences between the two types of synchronization.
“Estrus synchronization programs are used to shorten the time to the next heat while ovulation synchronization programs actually attempt to synchronize the precise timing of ovulation, thus allowing for the timed delivery of an insemination while maintaining a high level of fertility,” they say.
The article includes advice on using estrus and ovulation synchronization in the lactating herd, as well as diagrams that outline specific estrus synchronization protocols, ovulation synchronization protocols and presynchronization strategies for lactating dairy cows.
