HILLE G534 QUEEN BEE

VIEW ASSOCIATION INFO  

Queen Bee is a donor added from the Chimney Butte program in North Dakota and came to us as the most sought after featured homozygous polled purebred bred heifer of the sale.  Her 11 year old dam was the highest selling aged cow in the recent Chimney Butte dispersal and Queen Bee has been a great producer of not only embryo but also progeny.  Her Sitz Stellar son was the second high selling Balancer bull in the 2024 sale and her purebred son, R.O.I. is our 2025 Purebred Futurity Runner Up that we will be using heavily in our program. R.O.I. was named Junior Bull Calf Champion in Denver at the 2025 National Gelbvieh Show.

VIEW ASSOCIATION INFO  

Black Homo Polled 75%

This donor cow is the result of an embryo purchased from Cedar Top Ranch in our effort to add the famed 198L cow family to the Post Rock program. 82F was introduced to the breed in a big way in 2023 when her Homo Black, Homo Polled son Post Rock Prominent 139K8 was selected by Balancer Futurity members as the 2023 People's Choice Balancer Bull Futurity Champion. At our 2023 production sale her purebred Homo Polled Black son topped our sale at $16,500 selling to Flying H Genetics. Both of these bulls are being used heavily in our AI and ET program. 82F was injured and has retired early in life making her progeny even more valuable and rare.

Sitz RLS Eisa Evergreen 5404

VIEW ASSOCIATION INFO  

100% Angus

5404 was our pick from the Sitz' “Elite Sort” Female Sale in 2021 in hopes to add the “Maternal Prefix” into our Angus program. 5404 is absolutely ideal in her type and kind. Moderate framed, low maintenance, perfect uddered, and simply cowy in every sense of the word. She possesses what we feel an Angus donor should; the ability to produce calving ease bulls with adequate growth that will move an operation forward by retaining heifers.

BEAR MTN EULIMA 7548

100% Angus

7548 was purchased from Bear Mountain Angus in their “Major Herd Reduction Sale” in 2023. After doing our research and thumbing through the catalog we landed on 7548. She is already a proven producer and we plan to heavily populate our Angus herd with her daughters to come. 7548 embodies our search emphasis and selection pressure regardless of breed by combining calving ease, performance, and eye appeal with an emphasis on foot and udder quality.

POST ROCK TWILA 223M2

Post Rock Twila 223M2 is a true legend in the Gelbvieh breed. Her first son was Post Rock Granite 200P2 who was the number one most used Gelbvieh bull in the breed in 2013, 2014, and 2015 based on registrations.
