We have a gilt who has been stalled at 215 for 4 days. She needs to be 225 by 4:00 pm on Monday. She is healthy and has been wormed. Any advice before we weigh?

We have a gilt that has stopped gaining weight! She weighs 215 and needs to be 225 by 4:00 pm on Monday. She is very healthy and has been on a good worming schedule. She has been stalled at 215 for the past 4 days. We would appreciate any advice!
