[QUOTE="Arnold Ziffle, post: 404269, member: 43"] Txwalt -- in Texas and the South we frequently see Char bulls with Brangus, Beefmaster and/or "tigerstripe" cows to obtain growthy terminal cross calves that are no more than 25% Brahman influenced. ( In my area years ago, before the Char rage began, many folks used Simmental bulls as a terminal sire. ) Those are essentially three-way crosses. I guess the oldtimers out in the country figured things out a long time ago without the fancy studies. But I think you'll find that many researchers believe heterosis to be maximized by using a three-way cross and also by the use of the most dissimilar breeds --- such as combining English and Continental (bos taurus) with one of the bos indicus breeds (Brahman, Nelore, Gyr, etc.).
