I'm in Kentucky and I'm trying to decide which bull to put with our black cows with the possibilty of keeping heifers. I know Baldy cows are extremely popular for various reasons but we have about 30 Simangus cows that seem to always raise the best calves, possible due to milking better. Which do you think makes the best mama cow? On the Baldy cow I guess I could put a Gelbeivh bull and on the Simangus probably a Hereford.
