erwin de heerName: Erwin de Heer DVM

Short introduction:
In 2005 I received my BSc (animal husbandry) at the University of applied Sciences Den Bosch. Nearly six years later I graduated (DVM) at University of Utrecht. I started my veterinary career at a specialised farm animal clinic “t Groene Hart” in the Midwest of the Netherlands. During that period I gathered deep interest in dairy cow nutrition and the complex interactions of grazing healthy cows with their environment.

I am currently working as a veterinarian at the University Farm Animal Ambulatory Clinic (University Utrecht). Since June ’18 I started as a freelance dairy consultant with a special focus on farm data-analysis, nutrition and agronomics.


ruud hendriksName: Rik Hendriks DVM

Short introduction:
After being graduated in 1992 at the Veterinary Faculty in Utrecht, he started to work in the veterinary practice as all-round veterinarian. In 1993 he started working at the Veterinary Clinic in Ell, of which he now is co-owner.

His work gradually shifted from an all-round veterinarian to a bovine practitioner. Since 2003 he got in contact with the inside-outside approach and since then this has strongly influenced his way of daily acting in the field, and when giving presentations.

Rik Hendriks is:

– bovine practitioner.

– IKM-trainer; he gives training sessions in Integrated Cow Management (IKM in Dutch) for bovine practitioners.

– teacher in “External Education”; i.e. he coaches and teaches veterinary students from the Utrecht Veterinary Faculty during a 10 weeks period in the final 6 months of their study.
