Romosinuano

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

It wasn’t till the 1990s that Romosinuano came to the attention of scientists in America. Even then, 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.

Our foundation Romosinuano females came from the herd of Dr. Adelberto Garza of Edinburg, Texas, who procured 25 full-blood female Romosinuano from the Brooksville sale around 2009.

Our male line descends from semen we obtained from pure Romosinuano bulls that trace directly to Venezuelan bloodlines.
