Estrus Synchronization a Reality with Planning Software

4/13/2007

AMES, Iowa -- Synchronizing the breeding season in beef cattle herds allows producers the opportunity to use artificial insemination  (AI) with reduced labor. 

 

“Using the best, highly proven sires available in the beef industry can be an economic and labor reality with a little bit of planning and execution,” says Daryl Strohbehn, extension beef specialist at the Iowa Beef Center (IBC) at Iowa State University. 

 

During the fall of 2006, the Iowa Beef Center announced a new and improved software program to assist producers in making choices in estrus synchronization of their beef herds. The ‘Synch06’ edition of the Estrus Synchronization Planner is now available to producers and has several new features as a result of the combined work of the IBC and the Bovine Reproductive Task Force.

 

“Just think, not only will a major portion of the bull calves be by top AI sires, but all of the herd’s potential replacement heifers can come from superior sires. Imagine the future economic impact these females can have on herd productivity and revenue generation,” Strohbehn continued. 

 

"This dedicated group of reproductive physiologists from the Bovine Reproductive Task Force has worked for several years to make AI systems efficient for use in many different management situations. The IBC is privileged to work closely with this group to offer a low-cost tool to assist beef producers in planning, calendarizing and doing cost analysis of the many proven synchronized breeding programs."

 

Synch06 assists producers with the basics of planning and implementing complicated synchronization programs. However, the new edition has several new, exciting features, including the latest recommendations of the task force, plus updated fact sheets on synchronized breeding plans.  A new, preferred synchronization system for heifers using fixed-time AI was approved last fall during a meeting of the task force.  It is the 14-day CIDR application pioneered at the University of Missouri called “CIDR Select.”

 

Features included in this version of the Estrus Synch Planner are:
        - 14-day CIDR synchronization program
        - 17 estrus synchronization systems, in three categories, including fixed-timed AI, estrus detect with clean-up AI and estrus detect AI
        - 13 recommended systems for heifers and cows
        - 4 less preferred systems for heifers and cows
        - A daily calendar of activity once the system and date of breeding have been established by the producer
        - A budget cost analysis of the various synchronization systems

 

Producers, veterinarians, AI industry representatives and others can purchase the software for $35 (includes shipping and handling) by contacting the Iowa Beef Center  at beefcenter@iastate.edu  or (515) 294-BEEF, or by downloading an order form from the center’s Web site, www.iowabeefcenter.org

 

 

The Iowa Beef Center began operation in 1996 to support the growth and vitality of the beef cattle industry of the state. A part of Iowa State University Extension, the Iowa Beef Center is the central access point for Iowa State University programs and research related to the beef industry.
