Here is a bull we are using. He is Idalee Pioneer 812 ET and was from a set of embryos I purchased from the Horseshoe Creek 5th Frozen in Time embryo sale in 2013. He is sired by Saskvalley Pioneer 126P out of Six S Leah 55L. I don't know what he weighs because he is too big for my scales. He is a frame score 8.5 and it isn't all leg and daylight, so he is pretty heavy! His birth weight was 106 pounds from a commercial Holstein recipient and he weaned at 589 pounds from a free choice acidified milk replacer program. His first two calf crops were all born unassisted with an average birth weight of 89 pounds. They had an adjusted weaning weight of 703 pounds. All calves are on mother's milk, pasture and alfalfa hay with no creep. By comparison, a contemporary bull used on the same kind of females, genotypically and phenotypically, average birth weight of 86 pounds and an average adjusted weaning weight of 554 pounds. Calves from both bulls were on the same pastures and alfalfa hay, so this 149 pound advantage for Pioneer 812 is real genetic gain. His first daughters will be calving this spring, so his influence on maternal character can be evaluated at that time.
