Darrell Stevenson, an American cowboy and cattle rancher, is not riding the black earth country of Russia to film a western movie.
    He is bringing American-bred beef cattle, American ranching technology, and American cowboy knowhow to Russia.
    After the Soviet Union collapsed, beef production in Russia also collapsed. People just ate the herds as the system of sustaining the cattle broke down. Today, Russia, the world’s largest nation, imports most of its beef.
    Right now, Russia’s beef herd is less than one percent the size of the American herd, despite, as Stevenson points out, the country’s abundant land and water.
    Last year, Stevenson imported by ship and by air cargo jet 1,400 black Angus cows from Montana, in America’s west.
    A few months ago, they had their first calves, born in the black earth country of Russia. Stevenson, along with two Russian businessmen, has set up a ranch with the goal of establishing a commercial beef herd in southern Russia.
    Stevenson says Russia’s long term goal is to achieve self sufficiency in meat production, pork, chicken and beef.
