Abstract: White blood cell (WBC) counts of birds fed PCM supplemented diets were similar/comparable to that of the birds fed the control diet; however, the highest (P < 0.05) counts were recorded in birds fed diets 2 and 6. The hemoglobin concentration (Hbc) and packed cell volume (PCV) of birds fed PCM supplemented diets were similar (P > 0.05) to those fed the control diet, except for those fed diet 6 had significantly (P < 0.05) lower Hbc and PCV. The carcass and relative internal organ weight of the broiler chickens were not affected (P > 0.05) by the PCM supplementation. The dietary PCM supplementation produced a marked proliferation of polymorphonuclear and mononuclear cells, activation of liver macrophages system, the Kupffer cells in the liver of the birds. There were also reduced spermatogenic activities in seminiferous tubules, congestion of seminiferous tubules, tunica albuginea, and medial hypertrophy of the blood vessels in birds fed the 0.4 to 1.0% PCM supplemented diets.
