I would expect her to poo more if she is eating well, as long as it isn't loose then I am sure she is absorbing it. I have found nothing beer than the prestige, and would advise you stick with it.
My Jozi was showable 3 1/2 months after her first litter on the Prestige. This time I had her on a different food (had won one of the stakes classes so had a voucher) and she was barely showable by end of November 4 1/2 months after her second litter.
Certainly if you wnat your girl back in godo coat and muscle tone I would stay with the prestige.
You might try giving her a bit more as a fourth meal, but otherwise keep ehr on what she is getting, and once pups leave she will put weight on gradually. I would not try to keep her away from the pups if she wants to be with them, just make sure they ahve been fed by you first, so they are to full to take more than a slurp.
