Rainbow River Simmentals is a family run purebred Simmental seedstock operation located outside of the small town of Fisher Branch, in the Interlake region of Manitoba, Canada. We represent the second generation in breeding purebred Simmental cattle, continuing the program that my parents established under the name 'Lazy Rainbow River Ranch' back in 1981 with the purchase of their first registered purebred Simmental bull. Our farm currently consists of 115 red and black Simmental cows, all of which are registered purebreds, and also 1000 acres of grain land.


Our Focus:

Disposition: First and foremost, it is mandatory that our cattle have docile temperaments to make them easy to handle at all times. If any bull or female does not have a quiet disposition, they are culled - no excuses. Our 'zero tolerance for bad attitudes' policy has always been strictly enforced. In turn, we receive many compliments on the good dispositions of our cattle. 


Sound Structure: Soundness trumps all other phenotypic selection criteria in our program. A sound foot, as well as sound leg, joint and overall skeletal structure is imperative for ensuring a strong structural foundation and longevity for each breeding bull and female. 


Udder Quality: Functional udders that facilitate newborn calves nursing without assistance are of utmost importance. We select hard for balanced udders with tight suspension and small teats that are equally spaced. These traits result in udders that are problem free for the lifetime of the cow.

Fertility & Easy Fleshing Ability: For our program, these two criteria go hand in hand. A short 50-day breeding season is utilized each year to insist on high fertility. Our main cow herd is solely fed forages and they are not supplemented with grain at any point during the year. This management strategy helps us naturally select for fertile, easy-fleshing cattle who thrive on forages.

We like our cattle to be functional, big volumed, moderate framed, and exemplify the milk production, growth and natural muscle expression that the Simmental breed is known for. Strict culling ensures only the most productive cattle remain in our program. Artificial insemination and embryo transfer are used extensively to infuse superior genetics and uniformity into our genetic base. We also firmly believe in complete and accurate data collection and reporting because it's impossible to reach a target or improve something if it is not measured. 


Our bulls and select open heifers are sold in our Annual Bull & Female Sale held on the second Friday of March each spring. Females, semen and embryos are sold privately off the farm and consigned to fall sales normally held in November and December. We use the show ring as a marketing tool and also as a fun way to keep in touch with our friends in the cattle industry. Our cattle can be found on display at various summer fairs in Manitoba, at the Manitoba Ag Ex and the Canadian Western Agribition. Alternatively, we love showing our cattle to visitors on the farm and the coffee is always on!  If you're ever in our area, please feel free to contact us to arrange a herd tour.
