Our Main boar up to this late fall is 2 1/2 yrs old and had a 100% cover on the first heat. He went to my duaghters in SD and had heat stroke while there. Since he came back we have bred 3 proven sows all showing heat again. And 2 gilts one bred 3x the other 1x. Plus my brother has 3 sows 2 AI's one a sow one a gilt. Both open, I have a sow which I bred to my BIG boar who then cover my brothers sows all open????? The old thing about the 3 bred to my main boar are loose, have mucus, but the boar is not interested in them. Could this be a false heat and the boar knows it? He is a great boar covers sows alot while in heat. We are wondering if anyone else is having problems or better yet has a good answer for us!
