Rainbow River Simmentals

Based near Fisher Branch, Manitoba, Rainbow River Simmentals is a second-generation operation managed by Dustin and Jennilee Stewart. The program specializes in Purebred Red and Black Simmental genetics, with a strict breeding philosophy centered on docile dispositions, sound structure, and udder quality. By utilizing a forage-only diet and a short 50-day breeding season, the ranch naturally selects for high fertility and easy-fleshing ability. Through extensive use of AI and embryo transfer, they provide predictable, high-volume seedstock designed for real-world efficiency.
