XtraVital Tropical Bird Feed is an extremely palatable, well-balanced, super-premium bird feed, developed in cooperation with nutrition experts, vets and bird experts. The varied composition of seeds and eggfood provides for the natural nutritional needs of tropical birds, like Zebra Finches, Strawberry Finches, Australian and African Finches. The food contains all the necessary vitamins, plus chelated minerals (minerals wrapped with a protein coating for improved absorption). XtraVital contains Echinacea, a plant extract, which maintains a healthy immune system, encourages speedy recovery after illness and promotes a better condition and plumage in all birds. Swapping from current feed to XtraVital does not require a changeover period.
