It is used as a bacteriostat to control post weaning piglet diarrhea. Research indicates that zinc is necessary to maintain the structural integrity of swine and poultry gastrointestinal tract and key in creating a microflora balance. Zinc increases the microbial diversity in the intestine and it upregulates the expression of tight junction proteins. Inorganic Zinc oxide has low bioavailability and poses environment challenges. Slow released microencapsulated Zinc Oxide with its organic coating is more bioavailable, and because it has a higher active amount of Zinc Oxide, less is required to meet requirements.
