Dr Cathrine Sauer

B.Sc., M.Sc., Ph.D.

Nutrition Officer

I joined the Science team at Chester Zoo in 2015 and hold the position of Nutrition Officer. I mainly deal with the daily management of our extensive Animal Feeding Programme, by creating diets for new species arriving in the collection, reviewing existing diets and keeping an eye on our food budgets. I work closely with our curators and team managers, the Animal Health team and our Animal Supplies division to ensure that all animals in our collection receive the best nutritional care.

Prior to working at Chester Zoo I finished my PhD research at Aarhus University (Denmark) looking at the digestive tract anatomy and physiology of giraffes and other wild ruminants, as well as alternative ways of feeding browsing ruminants in captivity. I also hold a BSc and MSc degree in Animal Science from Copenhagen University (Denmark).

There is just so much we don’t know about the nutritional needs of non-domestic animals, but the field of zoo nutrition science is slowly growing and we are learning more and more about these beautiful and complex creatures that we have to cater for every day. Providing the right nutrition is one of the most important ways of making sure our animals are healthy and fit for breeding, which is absolutely key for many of the endangered species in our collection.
