Dairy Reproduction Protocols
New technologies have become available in recent years to
improve reproductive success. These technologies include
improvements to traditional approaches to reproductive management
(heat detection and A.I.) as well as to approaches that synchronize
A.I. so that all cows and/or heifers are inseminated at one time
(timed-A.I. programs). Combinations of traditional and timed A.I.
programs are also used on many farms. Regardless of the approach, a
focused effort on reproductive management has been shown to
increase pregnancy rates, translating to greater reproductive
efficiency on the dairy.
Synchronization protocols evolve rapidly as newer procedures are
tested and improvements are made. To help veterinarians and
industry professionals deal with rapid change and make informed
decisions related to synchronization protocols, the Dairy Cattle
Reproduction Council (DCRC) has created synchronization protocol
sheets for dairy cows and dairy heifers. The documents outline
established synchronization protocols that may help dairy producers
improve on-farm reproductive performance.
This document is intended for educational purposes as
consultants work with their dairy producer clients 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 sheets will be reviewed annually by
representatives from the DCRC. New protocols will be included when
they are validated in controlled studies.
