It is well documented that the weaning period is related to environmental and social changes which negatively impact the physiology, microbiology and immunology of piglets. Under commercial conditions the use of high doses of ZnO (2100 to 3100 mg/kg) in post-weaning diets has proven to be effective in improving animal performance and reducing piglet diarrhea.
As animal production becomes more and more sophisticated, previously unobserved factors that potentially hinder performance become a bigger issue. Intestinal commensal bacteria - bacteria that live together - fit this narrative.

Zinc is one of the most important nutrients for animal growth and health. It is the key component for numerous proteins, crucial enzymes and transcription factors. Throughout the world, pharmacological levels of zinc oxide are used in weaning pig diets to promote growth and improve feed efficiency, as well as help piglets cope with post-weaning challenges like post-weaning diarrhea, bowel edema disease and reduced feed intake.
