Weaning is one of the main challenges in the piglets life. It combines changes in local protection, caused by sudden withdrawal of maternal milk with IgA’s, declining immunity against pathogens to which will be exposed after weaning, changes in the intestinal tract (structural and functional) to adapt to a new different diet, insufficient stomach acidification and inability to fully use the nutrients available in the diet immediately after weaning. All these challenges often lead to post weaning diarrheas. Currently pig veterinarians rely on antibiotic treatments during the post weaning period and on Zinc Oxide at higher doses included in the post weaning diets. Due to concerns about the accumulation of Zn in the environment and the potential to the development of antibiotic resistance due to the use of ZnO and metaphylactic or prophylactic antibiotic use Vahjen et al (2015), ZnO at higher than the physiological required is being banned from June 2022 and new restrictions on the use of antimicrobials also came in place in January 2022.
