Whoever has followed Holstein history over the last 40 years knows that the requirements of modern sires changes with time. Certain traits become more important relative to older traits, or less important relative to newer traits. Recent years have not been an exception to these changes. Today, fitness values carry more weight. Framesize, teat length, and functional feet and legs are gaining importance. And not to be forgotten is the increasing value of fat production. The modern sires of today are able to bring together exactly these characteristics. And Masato, Germany’s highest Mogul son, is of that caliber. He is perfect for his time.
