I have a tamworth boar right now that is getting a little too big. I have access to a berkshire boar. We raise pasture raised pork and we have been satisfied with the meat. They are a little slow growing but otherwise great. However the boar has always been a little off. He is very difficult to move when needed. He is also not very good as a pasture animal. While all the cross bred pigs are out forraging, he is hanging around the pen waiting for grain. I am not happy with this since the tamworth is supposed to be the best pasture pig going. We also have several sows that should have farrowed, but they have not. I think they are bred, but I am not sure. The current owner of the berkshire is selling him because he found his meat was too fatty. We don't want this. However he constant feeds his pigs. We limit their feed. Which may make a differance. Anyone have experience with both breeds?
