Jan Druyts


I am Jan Druyts, CEO and owner of Nukamel, the founder of calf milk replacers back in 1954. My family has always been and still is active in agriculture and I graduated as Agricultural engineer at Leuven University and Master in Economics at UFSIA Antwerp.

Today we are challenged by the change of our economy to a carbon neutral environment as well as an antibiotic usage free farming area. This is the real challenge that Nukamel likes to contribute too…!

I grew up on a dairyfarm in the Netherlands and also studied agriculture. Later my family moved to eastern Germany and ran a dairyfarm there.

I found my passion in calf raising and decided to found Dairytop BV a company who does specific calf consulting on the farm and sells all the products in a very good quality you need to raise a calf.

Since years I travel through Europe and the world, to see the newest things around calf raising and see foreign farms because dairycalfs are my passion.
