I have not personally had any Normande 's but a couple of the dairies I milk test have had some. They are a nice cross with holsteins... hold their flesh real good... and milk real good with good fat % on test. Might make a good cross with a guernsey... never thought of that. Might get some semen ... I don't think I have any in the tank when I bought out that guy a few years ago.... and use it on the hol/jersey/guernsey crosses I have.... Thanks for the idea....
Also have seen some Montbeliarde crosses and they make good "fat" milk cows that milk good and stay in real good flesh.
