Isa Cattle Company Pacesetter Award 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 35 L Bar bulls or sons of L Bar bulls that are trait leaders in the Beefmaster breed. That is 23% of all trait leaders—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.

52nd Bull Sale—October 5, 2013

Celebrating its 40th anniversary in print!

"I am a young cattle farmer (with 50 head of Nguni breed). I am based in Eastern Cape, South Africa. I read recently from a farmers' weekly magazine of a young Nguni breeder in the Western Cape, South Africa. He attributes his success in cattle farming from the teaching he has learned from reading your book, The Lasater Philosophy of Cattle Raising."
