Welcome back to Genetics & the Gavel, powered by American Cattlemen Media. Just ahead, we have Aaron McKinney, he's the field editor for American Cattlemen Media, and he sits down with Mason Fleenor, Owner of GG Genetics. In this episode, Mason and Aaron will dive into the GG Genetics & Mars Angus Performance with Superior Taste Bull & Female Sale , held on March 5th, 2026, at Ida Grove, Iowa. 

Mason Fleenor, the owner of GG Genetics, traces the operation’s origins back to the purchase of red heifers in Montana in 1986 and describes how the business has evolved into a performance-driven Angus program. He highlights his family’s involvement and stresses the importance of bringing younger generations into the cattle business. A recurring theme is stewardship: teaching youth to manage cattle, land, and resources while maintaining profitability in a demanding industry.

The core of the conversation focuses on genetic selection for efficiency and carcass traits. Mason explains his emphasis on high marbling, low dry matter intake, and overall growth, describing how the program uses tools like Grow Safe units and partnerships in Mexico to measure intake and validate performance of cleanup bulls. He goes into detail on the sire group, especially an ABS bull, Dave Sue Ever Clear, praised for low intake, moderate frame, and consistency. Mason notes his satisfaction with the uniformity, EPD profiles, and real-world functionality of the bulls in this year’s offering.

The sale itself will feature 52 yearling Angus bulls, one two-year-old bull, 13 bred heifers, and 10 open heifers, including females sourced from the Broken Chain Ranch in Montana. Mason discusses calving ease, birth weight, maternal quality, and how weather and management influence cattle performance. He also describes logistics such as shipping, the importance of experienced auctioneers, and the availability of online bidding through Superior Livestock Auction. The conversation closes by inviting listeners to learn more about the program and consider the offering as a resource for improving efficiency, carcass quality, and long-term herd direction.
