“I have been a Holstein breeder for 20 years and from the beginning my goal was to have a uniform herd. In the early years, I used just three bulls suggested by the common mating programs. The results were the opposite of what I expected. My herd became less and less uniform. I started using the aAa Weeks method in 2011 and the improvement has been exponential. My herd is becoming more and more uniform; calving or post-partum problems have almost disappeared. I have more heifers without using sexed semen and the vitality of the calves is remarkable. Even the temperament of the animals has improved; they are more docile.”
