I am having A hard time finding a good boar for my sows. I have an uncut boar from my last litter of pigs that has all the traits I am looking for. Is there anything wrong using him as a new replacement boar? He would be breeding back to his mother, his mothers sister and a half sister. They all carry good traits that I would like to keep. I know it is normal breeding fathers to daughters and granddaughters but havent heard much about breeding the other way (mothers to sons). thanks for any suggestions.
