It can be a challenge to keep the various synchronization protocols straight in your mind, let alone successfully implement them on your dairy.

To help you and your management team more effectively manage your farm’s reproductive performance, a group of dairy reproductive experts have created a dairy synchronization protocol fact sheet. The two-page document outlines established synchronization protocols, making it an excellent resource tool for your reproductive toolbox.

New technologies have become available in recent years to improve reproductive success. These technologies include improvements to traditional reproductive management (heat detection and A.I.), as well as synchronization, so that all eligible cows are inseminated at a fixed time (timed-A.I. programs). Both approaches demonstrate that a focused effort on reproductive management can increase pregnancy rates, translating to greater reproductive efficiency on the dairy farm.

“Synchronization protocols evolve rapidly as newer procedures are tested and improvements are made, explains Matt Lucy, professor of Animal Sciences at the University of Missouri and president of the Dairy Cattle Reproduction Council (DCRC). This new tool from DCRC is designed to help farmers and industry professionals deal with rapid change and make informed decisions.

As such, the protocol sheet is intended to provide a foundation for discussion as veterinarians, consultants and dairy producers work together to make reproductive management decisions; the DCRC does not endorse one protocol over another, nor does DCRC endorse synchronization protocols over any of the other approaches to dairy cattle reproduction. The protocol sheet will be reviewed annually by representatives from the DCRC.

New protocols will be included when they are validated in controlled studies.
