My Father-in-law was in the Polled Hereford business for over 30 years. He sold all his calves as commercial at the area Sale Barns, and always got docked on his red/white calves. He finally bought a commercial "Angus" bull to produce black baldies. He did get some black baldies, a few red baldies, some solid black, and an occasional solid red calf. After several years of seeing his Grand daughters win show after show with their Home Grown Maine-Anjou heifers, he bought a Maine-Anjou bull from me. This bull was neither homozygous black, nor homozygous solid patterned ( I'm talking back in about 1995). He still got about the same mixed bag of colors in his calves, but received a premium at the auctions with his 50 lb. + higher than average weaning weight calves. In 1999 I sold him a Draftpick X Streamliner solid black PB Maine-Anjou bull. Many of his best cows by now were black baldies, sired by the "Angus" or the Maine-Anjou. The last bull sired all solid black calves, smaller framed, deep, springing ribbed calves like the Herefords, but with the bone and muscle of the Maine-Anjou. His calves topped the sale every time he hauled a load into town until he sold out in 2004 due to health reasons.
To sum up this tale: Your Ali X Hereford calf will look much better than it's Mama!
