ABSTRACT: The objective of this work is to show the effect of residual blood on the quality of chicken meat, work based on the hypothesis that increasing the concentration of residual blood would explain the observed quality degradation by several authors. Lots of chickens are killed with two different types of slaughter: Slaughter without stunning for a maximum flow of blood or bleeding perfect PS, shooting seals slight lead to keep almost all blood from the carcass or bleeding IS flawed. To prove the residual blood factors that are responsible for high pHu level and high values of (L* A* B*) in poultry, this study compares the pHu level and values of (L* A* B*) in poultry both perfectly and imperfectly bled. Samples from imperfectly bled carcasses show a high value average number of A* = 12.68 and B* = 16.85; and L* = 54.09 VS the average number of A* = 8.50 and B* = 14.43 and L* = 50.27. At 3℃ storage temperature, the average pHu of perfectly bled poultry was (5.7) which was significantly (P
