Our Mission
We breed low‑input, highly resilient cattle that deliver tender, flavorful beef.
Breeds offered include:
• Pure Romosinuano
• Akaushi × Romosinuano
• Red Angus × Romosinuano
About Romosinuano Cattle
Romosinuano are a tropically adapted Bos taurus beef breed native to Colombia. They are noted for their fertility, longevity, pest and parasite resistance, docile temperament, hardiness, being polled, combining ability with other breeds, high carcass yield of marbled meat, and high heat tolerance.
The gene responsible for high heat tolerance in Romosinuano is called the “slick” gene, because it results in slick-haired offspring. Romosinuano naturally carry a double copy of this gene, making it highly heritable. (See Slick Gene Helps Cattle Beat the Heat.)
Romosinuano in America
In the 1990s Dr. Chad Chase and USDA researchers identified this breed’s potential, launching decades of research at the Brooksville Research Center (FL). Cross‑breeding trials repeatedly showed Romosinuano‑influenced animals maintain health, performance, and fertility under heat stress. And it nearly didn’t happen (see Story of Dr Chad Chase and the original embryos).
For the following thirty-five years, the USDA at the Brooksville Research Center in Florida, in conjunction with the University of Florida, ran multiple long-term cross-breeding programs using Romosinuano, all of which proved the genetic merit of the Romosinuano breed.
Kaizen Cattle’s Romosinuano
Kaizen Cattle is committed to continuous improvement in breeding versatile, adaptable, and heat-tolerant cattle. To that end, we are also committed to the preservation of the Romosinuano breed, for all of the genetic advantages it brings to the game.
Kaizen Cattle’s Romosinuano females trace back to Dr. Adelberto Garza’s carefully selected herd from the 2009 Brooksville sale, an effort many credit with saving the breed.
Our bulls descend from pure Colombian bloodlines imported from Venezuela as embryos by Dr. Chase and the USDA.
We remain dedicated to preserving this rare breed and leveraging its proven genetics for consistent performance in harsh environments.
