Impact of Zinc Hydroxychloride and Oxide Nanoparticles on Broiler Chicken Growth, Gut Microbiota, Immunity and Serum Biochemistry

Veterinary Medicine and Science, Volume 11, Issue 2, March 2025.
The current study aimed to compare three levels of zinc (40, 80 and 110 mg/kg of diets) as either ZnOHCl or ZnONPs. It is shown that ZnOHCl supplementation in broilers’ diets up to 110 mg was more efficient than ZnONPs in most responses relevant to immunology, growth performance and meat quality.
