The Effect of Nano Zinc Dietary Supplementation on Growth Performance of KUB Chickens

Abstract

Current trial was intended to study the effects of nano zinc dietary supplementation on the growth performance of KUB Chickens. Two hundred KUB chicks were distributed randomly into five treatment levels with four replications, and ten chicks in each replicate pen. The dietary nano zinc treatments were: basal diet without nano zinc supplementation (NZ-0) and a basal diet supplementation with nanoparticle zinc oxide at concentrations of 15 ppm (NZ-1), 30 ppm (NZ2), 45 ppm (NZ-3), or 60 ppm (NZ-4). The observed variables were body weight gain, feed intake, and feed conversion ratio (FCR), based on the 10 weeks rearing period. The pooled data were analyzed statistically with one way ANOVA and followed subsequently with Duncan’s test for the data with significant difference. Results indicated that dietary supplementation of 60 ppm nano zinc increased body weight gain (P<0.01) and feed intake (P<0.05), and reduced FCR (P<0.05). Taken together, our data indicated that the growth performance of the KUB chickens improved when the diet were supplemented with 60 ppm nanoparticle zinc
