The study investigated how dietary nano-zinc affects the immune response and antioxidant activity in broiler chickens.
Ninety-one-day-old chicks were given diets with varying levels of zinc oxide nanoparticles and were examined for immune markers and antioxidant enzyme activities over a 5-week period.
Results indicated that birds receiving zinc oxide nanoparticles showed improved antioxidant enzyme activity and higher immune responses, suggesting that these supplements can enhance the overall health of broiler chickens.
