| Males parents broiler (Fawbro) were used to investigate the effects of adding three different level of oyster mushroom to broiler ration on some physiological and production characters.Four treatments were used at two week of age CON, P1, P2, P3: CON without adding mushroom. P1, P2, P3 adding o.5, 1, 1.5% oyster mushroom respectively to broiler food the experiment continued to 8 weeks of age. Packed cell volume (PCV), Red blood cell (RBC), differential counts of WBC, cholesterol, glucose, total protein, total globulin, uric acid and the activity of ALP, GOT, GPT enzymes in blood serum, percentage of some internal organs (liver, heart, gizzard, spleen, abdominal fat), intestinal and proventriculus length percentage, caracas pieces were calculated .The result revealed that there were an increased ( not significant) in PCV, RBC for p1, p2 , p3 compared with CON while a significant (p< 0.01) increased in basophile for P3 at 8 week of age whereas there were significant decrease in blood glucose cholesterol concentration at 6, 8 weeks of age for p2, p3 compared with CON, also there was a significant increase in total. Plasma protein for P2, P3 at 6 week of age a significant increased in total plasma protein and ALP enzyme activity at 8 weeks if age for p1, p2, p3 compared with CON. Also there were a significant increased in total globulin at 8 weeks of age for p2 compared with p1 in contrast there were a significant decrease in uric acid and GOT, GPT enzyme activity of blood plasma for treatment P1, P2, P3 compared with CON at 6, 8 weeks of age while the increased in ALP enzyme activity for all treatment compared with CON at 8 weeks of age. Dressing percent and thigh, drum stick heart weight increased (not significant) while wings, liver percentage and intestinal length decreased (not significant).The study confirmed the importance of adding oyster mushrooms in food as a nutritive and medical mushroom to improve the physiological and health status of broiler chicken and its effect on consumer and also improvement of production. |
