Just like Rold, Vilomix was also intrigued by the zinc oxide challenge and wondered what role it could play to make the transition as smooth as possible for producers. Dr Kristina Sørensen is product man- ager at Vilomix and has the task of finding a good response to the ban on zinc oxide. She explains, “In fact, the zinc oxide issue is all about weaning. You just don’t want the ‘bad guys’ (Escherichia coli) to take over in the gut of weaner pigs. Zinc oxide suppressed the effect of E. coli very well.

She found 15 learning-savvy Danish pig producers willing to open their doors for a thorough in- spection by this team to figure out what further actions they could take. Anders Rold was one of them and became involved after en- quiring about the project with his premix producer. He says, “I reached out to Vilomix because I was curious about what would happen once the ban on pharmacological levels of zinc oxide was fact. I wondered if they were ready and, if so, how we could do it.”
