The goal of the present research was to evaluate effects chromium-loaded chitosan nanoparticles (Cr-CNPs) on production performance, viscera development, serum metabolites and intestinal histology in broilers. Two hundred (200) day-old broilers were randomly divided into five groups with replicates (n = 8). Birds first group served as control fed a corn soybean-based diet, while remaining four supplemented offered 200, 400, 800, 1200 μg Cr-CNPs/kg feed, respectively, for 35 days. Weight gain, feed intake conversion ratio (FCR) remained unaffected Cr-CNP supplementation. No changes observed relative weights viscera. length small intestine decreased birds 200 800 compared Cr-CNP-supplemented control. Serum supplementation except HDL, which increased. Cr-CNPs retention chromium bone at higher concentrations. Jejunal villus height, surface area, height crypt depth increased group. In conclusion, did not affect growth most metabolites, but enhanced jejunal morphological attributes feed.
