Think About It...

What Should a
Proven Embryo Cost?

Over the past 3 years, calves produced from the embryos selling April 30 have combined to produce an average selling price of $7,555 on 48 head...the Top 38 have averaged $8,969/hd...
In the March 2022 Mimms Calf Sale 23 full mates to the embryos selling here combined to average $9,163 where 11 brought more than $10,000 and 4 sold for more than $20,000.
At just 50% conception and even with 50% heifer calves plus $1,000/hd production cost, what does that make a proven embryo worth? Do the math. The proven good stuff is WELL worth it.

Major Success Starts Here.

I would like to take this opportunity to thank all of the sponsors and those who contributed to the 605/806 Memorial Fund. This memorial honors the lives of three people who had an unknowingly large impact on the cattle industry. I am extremely fortunate that I am able to live through the legacy that they left and make an impact of my own. Your generosity does not go unnoticed and I am very honored to be a recipient of this award. I am currently a student at South Dakota State University studying Animal Science with minors in Ag Business and Ag Marketing. I hope to one day pursue a career in the field of livestock genetics. Thank you once again for supporting the future of the cattle industry.
