The Beefmaster breed has proven through various studies to be the most efficient breed for beef cattle production in the many diverse ecosystems of the United States—from the arid desert to subtropical Florida, to the northern states with their harsh winters. But a new study in Panama shows Beefmasters achieving excellent results in the hot and humid tropics, one of the most difficult environments for cattle production.
After analyzing the results, IDIAP researchers concluded that 50% crossbreeding of Beefmasters in commercial herds has a positive influence on the indices studied. They also found that as the percent of Beefmaster blood increases in the same commercial herds, reaching 75%, the improvement of all the indices is much higher.
This study is the first to evaluate the impact of Beefmaster genetics on beef cattle production in the tropics. The cattle clearly performed well in all the phases most relevant to profitability. These results demonstrate that the Lasater Philosophy, with its Six Essentials, is the best method to maximize economically important traits in any environment.
