You got answers from the 2 most knowledgeable Brahma breeders on here, Caustic and Brute. I have fooled with a LOT Of Brahmas in my life, but I will defer to them when they say something different than what I think. You can not go wrong following the chart Caustic posted, but if you do want to breed British cows to Brahma, then do what Brute said. On another thread today someone posted some nice half Brahma calves out of sale barn angus and black baldies.. so you CAN get away with it. I have seem then bred to Simms, Charolais, Chianina, Chi-Angus, Longhorn and even Corriente with no problems. I know a man that has one of those raw milk organic dairies and has Jersey, Brown Swiss, Guernsey and Ayshire cows, and he breeds them to Brahmas. The few times I have seen calving problems, though, was with Ang and Herf cows. People do it...it's lot cheaper to buy a herd pf Ang or Herf and a brahma bull, than a herd of Brahma cows and an Ang or Herf bull.
