Welcome to Isa Beefmasters—
Performance Beefmaster Genetics from the Founding Family!

Home of Lasaters' L Bar Beefmasters, Isa Beefmasters is very proud to have had 100 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.

Isa Cattle Company Pacesetter AwardBBU publishes the trait leaders for each of the EPDs, and there are 42 L Bar bulls or sons of L Bar bulls that are trait leaders in the Beefmaster breed. That is an unprecedented 40% 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 all-time performance champion in the Beefmaster breed, having topped the charts in weaning weight, yearling weight and scrotal circumference EPDs.
