The search for weaning pigs without therapeutic levels of zinc oxide continues. As Denmark prepares for a 2nd edition of the Zero Zinc Summit in June 2022, various approaches and strategies are being researched, writes pig housing and welfare expert Vivi Aarestrup Moustsen.
In recent years, SEGES Danish Pig Research Centre has conducted several trials in the pursuit of finding the most cost-effective solutions of replacing therapeutic zinc from weaner diets without an increase in the need of antimicrobial use.
Solutions to overcome the removal of zinc oxide can be simultaneously changed procedures, reduced protein levels in feed and increasing the feed particle size. The solutions can impact production costs and in addition, faster diagnostic tools are needed. Here are a few highlights.
