The objective of the current study was to investigate effects stocking density (SD) and dietary supplementation vitamin C on growth performance, meat quality, intestinal permeability, stress indicators in broiler chickens. conducted using a completely randomized design with 2 × factorial arrangement consisting different SD supplemental levels C. A total 1,368 Ross 308 chickens 21 days age similar body weights (BW) were randomly allotted 1 4 treatments 6 replicates each. Different numbers birds per identical floor pen (2.0 m 2.4 m) used create low (9 birds/m2) high (18 birds/m2). basal diet formulated no meet or exceed nutrient recommendations manual. other prepared by supplementing 200 mg/kg diet. lasted for 14 days. At end study, 3 male replicate selected analyze such as blood heterophil:lymphocyte (H:L) feather corticosterone (CORT) concentrations. Results indicated that there interactions between all measurements. For main SD, raised at had less (p < 0.01) BW, BW gain, feed intake increasing responses including greater H:L CORT concentrations than those SD. Transepithelial electrical resistance jejunal mucosa decreased 0.05) indicating an increase permeability. However, insignificant In conclusion, impairs performance barrier function responses. may have little beneficial condition present study.
