I have a half Duroc half hamp boar, every sow I catch that is open spends 2-3 weeks in the pen with him before they go! It's helped the look,the size and all that damn RUNNING! I've been using him for 4 years had a spotted Poland China I used before him, it's working for me might be something you fellas could try
That's cool, I've thought about doing that
