I guess it would help if you knew what they were and what we have used, we are breeding to show calves. Our donors are a Black Dice X Reflector and her daughter X Vegas. We have used: Kadabra, Power Plus, Heat Wave, About Time, Legend, Anchor and Dr. Who. The best 2 we did were Final Answer but we had monkey mouth issues on a few, and Vegas but we are looking to a high % Maine bull.
The second donor is a Dr. Who X Majors cow that is a Stout X Gold Stream, she has plenty of depth, but she needs some power not enough behind her. I added a picture of her from last April, she continued to body down, we bred her to Hard Core and she has a heifer calf that is a carbon copy of herself. I love this cow, I just haven't quite figured out what I think will click on her. We bred her this year to Open Bar, I like the bull and the breeders backing him are in business for the long haul so we gave him a try.
