The ULP has proven itself in recent years as a safe partner for conducting practice-related research due to the large number of dairy and pig farms in our practice, the availability of data and the collaboration with the Faculty of Veterinary Medicine. We are ISO-9001 certified and have our ow laboratory (Click HERE for more information about our laboratory). This makes the ULP the partner you are looking for to conduct reasearch such as clinical studies and registry studies, prevelance studies, welfare studies an surveys.
The experienced research team consists of veterinarians with a doctorate, European specialists (dipl. ECBHM and dipl. ECPHM) and specialists in training. In addition, the ULP has an experienced research assistant who is responsible for practical implementation and data management.
In the field of research, the ULP offers you:
Since the founding of the ULP in 2009, a large number of studies have been carried out. Below you wil find the details of two studies and a overview of the studies that have been carried out. Most studies resulted in a scientific publication in a peer-reviewed paper or presentation at scientific congresses.
If you have any questions about the research possibilities we could offer or would you like to use our expertise in setting up a field study, then please contact us.
The following scientific publications have appeared from the various studies that we have conducted over the years:
