An Evaluation of Nano-silver as an Alternative Antibiotic on Performance and Intestinal Morphometric Parameters in Broiler Chickens

Document Type : Research Paper


To evaluate the efficiency of Nanocid as growth promoter in comparison antibiotics and with organic acids on performance and intestinal morphometric characteristics of broiler chickens, 240 male broiler chicks of one dayage (Ross 308) were utilized in an experiment of a completely randomized design of 4 treatments and 4 replicates. The experimental treatments included: 1) control (no additives), 2) antibiotic Virginiamycin (15 ppm), 3) organic acid (0.2% Formaycin), and 4) Nanocid (50 ppm). The antibiotic growth promoter group benefited from the highest final average weight (P
