Deborah Van Doorn

Utrecht University

DEBORAH VAN DOORN works at Utrecht University - Faculty of Veterinary Medicine, Department of Biomolecular Health Sciences. She is a senior teacher in veterinary parasitology.  In the past few years her research activities were mainly focused on the epidemiology of cyathostomin infections in horses and the resistance development of cyathostomins against macrocyclic lactones. Molecular identification of cyathostomin species and involvement in anthelmintic resistance. Resistance development of Parascaris equorum against macrocyclic lactones. Development of web based tool for practitioners, professionals and students (https://www.parasietenwijzer.nl/e/). Investigation of the attitude of practitioners and horse owners towards helminth control in horses. Incidence and prevalence studies of a variety of parasite species in horses and other mammals.

Therefore she invested in knowledge transfer through lectures and practicals/workshops and non scientific articles on animal helminth and protozoan infections. 

Wilbert Pellikaan

Animal Nutrition Group of Wageningen University & Research

Wilbert Pellikaan is assistant professor at the Animal Nutrition Group of Wageningen University & Research. In 2007 he obtained his current position within the Animal Nutrition Group with half of his time dedicated to lecturing subjects in general animal nutrition and animal nutrition physiology, and supervising undergraduate and graduate students. His main area of research is ruminant nutrition with a special interest in using novel tanniniferous fodder legumes in dairy cow nutrition to reduce enteric methane emissions. Since 2011 he conducts equine nutritional related studies within the Centre for Animal Nutrition, in collaboration with the Faculty of Veterinary Science at Utrecht University. 


In 2007 he participated as a workpackage leader in an EU funded research training network ‘HealthyHay’, focussing on the effect of sainfoin tannins on methane production. This project was successfully continued in a subsequent EU funded initial training network ‘LegumePlus’ (www.legumeplus.eu) in which he also participated as a workpackage leader of the animal nutrition section. Currently, he is involved in an FACCE ERA-GAS network ‘Methlab’, where lactic acid bacteria are being used as silage inoculants or direct fed microbials to reduce enteric methane emissions from dairy cows, and is a partner within the EU-funded project ‘Equianfun’. The latter program studies the functioning of anaerobic fungi in the equine hindgut, which are of key-importance to dietary fibre degradation.


Current research interests and projects include the use of alkanes combined with stable isotope technique to assess botanical composition in diets of free ranging ruminants and equids, the use of tanniniferous feeds in dairy cow and equid nutrition, and further developments of in vitro techniques to study fermentation processes and microbial responses in the gastro intestinal tract of ruminants and equids.
