I don't know much about British Blues but I have used some Belgian Blues on mature cows and every single one needed help, there are no easy calving BB bulls worth using IMV.Is that the same as the endless list of east calving blue bulls?
I said there’s only a few limmy bulls I would go back to to use
On the Limousin side there really is a huge selection of bulls available that are easy calving, even Elgin, who sired the world record price female and bull, has been used extensively on heifers.
