I don't know but I believe I read on here that the Brown Swiss is NOT a cow for the beginner or even a novice to deal with and are really something better left to an experienced cow person. I've also been told/read that Jersey bulls are the MOST dangerous (mean, opinionated, ornery, uncontrollable, deadly) bull to have to deal with. IOW, very much not recommended for a beginner. Aside from those 3 sentences, I'll defer to those who actually know what they're talking about @farmerjan @greybeard @WildRoseBeef & possibly a couple of others...
