When I had my saddlebacks the piglets scoffed her sow nuts til they departed. Now I buy weaners in at 8 week old and take them to 5.5 months if boars or just over 6 if gilts. I prefer boars as they are calmer, though the ones I got last year were little buggers! Anyhow, I buy pietrain x saddleback, get a bag of corn with them to help them settle and then feed wynnstay superwean (if they need it) hypergrow and then the last month is hyperlean. I've never had a problem with this corn.
