I'm reviewing our penguin diet and have some questions. We have African penguins who are fed capelin and supplemented with Mazuri Vita Zu small bird tablets (5M25). I've read through the Penguin Husbandry Manual, but I don' t have access to a nutritionist or the ability to have an analysis done. My question is, should we be using the vitamin form without the added Vitamin A or the form with it? We are increasing our dose to two pills a day because one was too low as far as thiamine supplementation.
Thanks for any information that you can share.
