Jennie is the association cow of the “Veetelers”. Since the beginning of 2015 she lives in the barn at Carus. Her father is DELTA ATLANTIC and she is 100% Holstein Friesian. Her birthday is on the 27th of December (2012). She weighs around 603 kg. On the 20th of November 2015 she has given birth to her calf. Hopefully she will grow up to be a noble research cow and they might soon enjoy each other’s company in the stable. If you ever happen to be at Carus, you can recognise her by the number 5758.


Ellen is one of the research cats of Carus and was born in 2014. She likes to be around people, so she is definitely an association animal! Her caretakers say that she performs well in tests. She is quite famous and many people want to adopt her. This will happen soon, which means that a new association cat will be named soon as well. When that happens, you can read it here.

Berend is the association pig of “de Veetelers”. He arrived at Carus in March 2019. He is of the breed Duroc, that is why his fur is a nice red color. Berend is a very nice boar and he is used for detecting sows in heat. When it is possible again, he will be used in the sperm practicals for Biology of Domestic Animals as well.
