In spite of being fed through the worst feeding conditions in my career, the Barnhart cattle were not only the fastest gaining heifers we fed during that time, but even more impressive, they grade 100% Choice or better with over 60%Prime. Truly remarkable genetics!

These cattle earned over $200 per head Premiums on the US Premium Beef Grid with 93.6% CAB and 59.82% Prime.

Research Collaboration

   "Dr. Barnhart,

I’ve listed publications in referenced journals from my lab that you collaborated on with us. In addition, it’s important to note that you cooperated with us as early as 2009 in conducting field trials with the 14-day CIDR-PG protocol we developed here at Mizzou. That protocol is now being used around the world.

Suffice to say, we appreciate all you’ve done in supporting our research over the years. My graduate students have benefited greatly from our collaboration with you and for that we are sincerely grateful.

Best regards.

Dave"
