Abstract:
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 chicken |
