We are the largest source of Beefmasters genetics in the world and serve customers around the globe.
We are very proud to have had 93 L Bar cows receive the coveted BBU Pacesetter award. This means that she calved at least by 30 months of age, she had at least three consecutive calves with a weaning ratio of 105 or better AND maintained a calving interval of 375 days or less.
On the bull side, BBU publishes the trait leaders for each of the 5 EPDs, and there are 38 L Bar bulls or sons of L Bar bulls that are trait leaders in the Beefmaster breed. That is 38% of all trait leaders—for the entire breed—more than any other breeding establishment! We are also the proud producer of L Bar 5502, the only four-time leader in the Beefmaster breed, topping the charts in weaning weight, yearling weight, scrotal circumference and ribeye EPDs.
