DK Zoological is the brand that Kiezebrink uses to develop products of their own. DK Zoological is a brand specialised in exotic animal nutrition. The products are being developed by their nutritionists in cooperation with veterinarians and zoos. With the development of a few very specialized products for, amongst others, primates and insectivores the brand quickly started growing. Nowadays it is used in a lot of zoos in Europe.
