We all know humans love beer! Apparently, pigs too
I recall an old farm hand telling me during my stay at Kansas the following method of preventing restless sows from attacking their newborns or refusing them their first milk.
He would pour a six-pack (I think it was Bud Light) in the sow's trough around the time of farrowing (or as soon as they detected the problem). Now, that's about half a gallon of good beer, and many would object seeing so much beer wasted, but he said there had been not a single failure to his method.
No personal experiences here, apart from drinking beer myself, but I would love to hear from you all if you have had similar experiences with farrowing sows (with any brand of beer, or course!)
