A study was conducted to establish a baseline profiles of various macrophage functions in four commercial chicken broiler breeds (local) designated as groups A, B, C and D. The experimental birds were between 4 to 6 weeks of age. Total number of peritoneal exudate cells per bird collected 42 hours after a single intraperitoneal injection of Sephadex G-50 were compared among these breeds, Groups B and C produced more macrophages than groups A and D. Macrophages from group B exhibited significantly higher and group A lower phagocytic activity for opsonized and unopsonized sheep red blood cells (SRBC). Macrophages from group A displayed significantly reduced bactericidal activity against unopsonized Escherichia coli. This study has thus demonstrated breed variations among the four commercial chicken broilers for mononucular phagocytic system functions.
