300# is what i shoot for. Dont switch to straight corn, ive done that, itll take foever to get there. I buy my feed from a local feed producer, so i dont know exact ratio. Bit it ground corn, soybean meal, and a hog vitamin pack. I like it because i know whats in it and it works. Most feed companies make a starter and finisher ration also. What kind of pigs are they?
