The current experiment was conducted to investigate the influence of increased stocking densit (as a management practice) in environmentally controlled (closed) and noncontrolled (open) broiler houses, on their internal parameters (body temperature, TD., Hemoglobin concentration Hb.g/dl, heterophil / lymphocyte ratio H/L, somatic indices of liver , spleen and bursa fabricus , B.f ) as well as their histological alterations and final productivity included live body weight (LBW /g) and mortality (M%). The results showed, Negative correlation between Ta. C° and TD. C° in control group of closed house .Increased NH, CO, concentrations and mortality % with age In open house positive correlations Were noticed between indoor Ta C and B.f index , between CO, and each of Hb. concentration , H/L ratio and mortality %. NH3 and COQ; correlated with Hb .concentration in birds of Indoor were positively open house. In closed and open environments, there were significant differences (decrease) in LBW between stocked and their control groups at 42 days old. Stocking significantly increased Tb .C Vs control groups in both environments but did not significantly affect hemoglobin concentrations. The H/L ratio in closed house showed non significant increase Vs control ,while in open house a little decrease was recorded in stocked Vs control. Conclusively, proper management could enhance stocked birds in current work to modulate their internal homeostasis to cope 0the resulted harsh microclimate with final
