Pengaruh suplementasi nano zinc dalam pakan terhadap efisiensi pakan ayam KUB

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 mg/kg (NZ-1), 30 mg/kg (NZ-2), 45 mg/kg (NZ-3), or 60 mg/kg (NZ-4). The analyzed variable data were feed intake, feed conversion ratio (FCR), protein intake (PI), protein efficiency ratio (PER), energy intake (EI), and energy efficiency ratio (EER) 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 mg/kg nano zinc increased feed intake, protein intake, energy intake (P<0,05), reduced feed convertion ratio (P<0,05), and increased energy efficiency ratio (P<0,01). Meanwhile, dietary supplementation of 60 mg/kg nano zinc did not affect the protein efficiency ratio (P>0,05). Taken together, our data indicated that the feed efficiency of the KUB chickens improved when the diet were supplemented with 60 mg/kg nanoparticle zinc.
