Production Animal Study Association​

We are a new study association within Ambrosia named PAS. PAS stands for Production Animal Study association and is related to the course Applied Animal Science and/or Animal Society and Business. PAS was created in 2021 by four Applied Animal Science students. 

Any student with an interest in Animal Husbandry can join PAS or one of our activities. 

Our goal is to organize nice activities for all AAS and ASB students. These activities can include an excursion to innovative farms, feed companies, or guest lectures from people within the work field and graduates from our courses.  

About PAS


PAS strives to provide applied animal husbandry students with various contacts and insights in the (Dutch) animal husbandry sector.


PAS will organize guest lectures and excursions to or from external companies related to the animal husbandry sector for students in order to achieve our vision.
