Do you have to allow for extra weight (water gain) when using this product?

We only have 11lbs to gain in 23 days. What wold you suggest. We've fed total control for 5 days then 111/2lbs of 12% showmax for 4 feedings. We fed your the holding ration for 2 feedings now. Do you have any suggestions? I don't think we are going to be fresh enough for the show

How long can you keep a pig on this ration?
