Rearing food for canaries, European and tropical finches Rearing food is essential during the breeding season; but also during the rest of the year, it is a source of extra nutrients. Does not contain egg products, to prevent unwanted additional colouring in light-coloured birds. Extra vitamin A is added, because these bird species are not or less able to produce this vitamin naturally. Complete ingestion because of a nice taste and a structure adjusted to the different bird species. With extra added lysine and methionine for optimal growth and feathering.
