I have about 16 purebred braunvieh cows and 13 or so 1/2 bloods. Two of the purebloods are over 13 years old and still producing. I bought several bruanvieh cows and a full blood braunvieh bull for a good base of moma cows. The bull was good natured ( was shown) and had a 92lb birth weight. He was used on the Braun cows as well as Charolais and Simbra, and never a calf pulled. He was NOT used on heifers. I have retained most all heifers from the cross as well. The past few years I have used a Hereford bull, and am very pleased with that cross. There is some stripping( not all) in the white face offspring, but that does not bother me here in Arkansas. I now have a black angus heifer bull for breeding the bruanvieh and the cross bred offspring.
I think a fat slicked-off bruanvieh cow is a beautiful animal. They are very fertile, especially the cross bred heifers. I had 2 get bred about 8 to 9 months old, not by choice. So, one should be set up to separate the bull from heifers early on. They produce plenty of milk, and are easy to work. They cross well with most breeds, and I have heard no complaints from Angus users. Most udders are set and hold up well.
Faults: My animals run on mostly bottom land, and some of mine will grow a long toe and require a little trimming. That may just be my animals. Do not notice it as much with the cross bred animals. If selling straight braunvieh at the sale barn, one could take a little hit, associated with the brown swiss. Cross bred would be minimal, especially when using a black hided bull.
I like the Braunvieh breed and the cross bred animals. They are not the norm, around here, so it is heard for people to associate the breed. I am a commercial guy. I got into braunvieh for a base heard of commercail cows,something a little different, and have not been disappointed. I believe the black hided calves will sell the highest for me this year, but I'm a big fan of Charolais and Hereford bulls. If I were starting over, and could not find some good braunvieh cows, I'd have a pasture of Charolais x Hereford cross cows, YWF. I'd then implement CB's thoughts on a black bull.
