Résumé

The research was carried out to determine the effect of dietary supplementation of nano zinc on growth performance and nutrient digestibility of broiler chickens aged 1 to 28 days. Two hundred Arbor Acre broiler chicks of a day old were randomly allocated four dietary nano zinc treatments, each consisting five replicates with ten birds per replicates using a completely randomized design. Treatments 1, 2, 3 and 4 containing 20, 30, 40 and 50 mg of nano Zn/kg and were tagged NZn20, NZn30, NZn40 and NZn50, respectively. The Birds were reared on deep litter and fed basal diets containing 20 % CP and energy level of 3000 kcal/Kg DM supplemented with varying levels of nano zinc for 28 days. Data generated were subjected to Statistical Package for Social Science (SPSS version 16.0). The supplementation of nano zinc enhanced (P<0.05) final and daily body weight gain, reduced feed consumed and mortality. The dietary treatments also improved CP, CFand ash digestibility. Chickens on diet supplemented with 30 and 50 mg/kg zinc had better result than those on 20 mg/Kg.
