BLOOD PROFILES, CEACA MICRO FLORA AND INTESTINAL MORPHOMETRIC OF BROILER CHICKENS FED DIETS SUPPLEMENTED WITH (Syzygium aromaticum, Piper nigrum and Tetrapleura tetraptera) AS ANTIOXIDANTS

250 unsexed day old broiler (Cobb) chicks were used to evaluate effects of phytogenic spices on blood profile, intestinal morphometric and gut microflora status. The study consist of five treatments namely: T1-control T2-synthetic antioxidant, T3 –T5 (Syzygium aromaticum, Piper nigrum, Tetrapleura tetraptera at 1% inclusion and replicated five times in a completely randomized design. Obtained results showed a significant (P<0.005) effect of phytogenic spices on haematological parameters with an increase in the value (37%) of PCV in birds fed synthetic antioxidants while lowest value (31%) was recorded in T1.The broiler chickens on synthetic antioxidants had highest serum protein (15.37g/l) as against (9.17-9.50g/l) in birds (T3-T5). Uric acid, creatinine, globulin, cholesterol values are normal while creatinine values (1.7 – 2.5mg/dl) reflects better protein utilization as confirmed by decreased uric acid values (0.81-1.74mg/dl). The active ingredients in the phytogenic plants reduced the Clostridium, Staphylococcus, Salmonella, Coliform, coliform counts in the ceacal contents while Lactobacillus and Bacillus population increased as recorded inT4. Increased villi height/crypt depth ratio (20µm) indicates improved intestinal health as well as increased digestive capacity of the small intestine in broilers fed T. tetraptera. The results trend showed that the present study is constituents dependent with optimal response with T. tetraptera meaning that these phytogenic antioxidants are able to replace the synthetic antioxidant under common feeding practice without any deleterious effect on intestine morphometric, blood profile and caecal microbial in broiler chickens.
