I picked up three 8 week old weaners 3 weeks ago - all GOS. I have been following the advice of the pig-keeper I got them from to feed them "ad-lib" to start with - there's always some pellets in their trough. However, I'm concerned that they don't end up TOO fat, so would appreciate some guidelines about when to control their feed, and how much to offer. I've heard that 1lb of pellets per pig per day per month of age is about right - what do others find that works?
