Hi Sue - I know we've PMd a ton about this - so I don't have much else to offer than the advice I gave there.
I would think it would take quite a while to suppress the overgrowth (using the Tylan as the agent) - just as it would take a good while to bring healthy flora *back* to the gut, when needed. The small intestine can be a tough one to bring into balance, but it can be done.
From what I went through with Marcel's gut - if this were me - I would plan for:
1) using the Tylan, fiber, digestive enzyme for 6mths - 1yr
2) deciding my ultimate nutritional goal of kibble, cooked, or raw
3) move toward a better diet (that ultimate goal) without changing ANY supplements/meds
4) maximize the nutrition so that THEN the supplements/meds can bring the intestine into balance
5) once the body has been on a premium, hypoallergenic, nutritional diet (with meds/supps) for a good 4-6 mths - then I would attempt weaning ONE thing at a time
That would be my approach, BUT - I would use a nutritionist (such as Susan Davis, who I've mentioned to you already) to help me achieve those goals.
