When I attrended the Royal Highland show in Scotland, the Blues had the largest show. ( they are called Bristish Blues there and are called Belgium Blues here). I must say that many of the commercial herds of half blood British Blue cows were quite impressive. Here are some pics i took there. The female was the Grand Champion at the Royal Highland. The white bull was Gran Champion Bull. He was simply disgusting!!!
The herd of cows pictured was very impressive and they were half blood Blue and they had very big calves on them. The blue colored cow was very impressive and probably would make a great clubby mom. She was tremendously deep and had lots of volume, with a great udder, and was as smooth as an apple.
