I haven't used Kadabra in the last couple years, but he has always been good for me on heifers. Conception rates were excellent, and the calves were always marketable. Steers did usually run into some structural problems as they reached market weight, but the heifers have always been pretty sound. That being said, those heifers have turned into some of the better producing cows we've got. They work very well in a variety of different breeding scenarios, Heat Wave or sons, purebred Maine, and Angus.
