I almost always keep Jersey cattle around for one reason or the other. I love Jersey steer beef. Other then a bit of extra bone, the meat is marbled very nicely, and they are in fact cheap to purchase as calves here still, thusly, they also remain the cheapest at the sale barn as adults.
But I do have a couple Jersey nurse cows I keep at least 3 to 4 calves on almost constantly, the are great peronality's, and good mothers to almost anything that wants to suck em.
Lancaster farmer paper just ran an article about several 4H groups now working Dairybeef calves..... and doing a pretty good job of it.............Beef is not a particular breed, it's defined as meat from bovine animals, ak cattle of any breed, and I think dairy breeds are still considered bovines eh? ;-)
