Blood and carcass characteristics of two chicken strains subjected to Ocimum graticimum leaf based diet as substitute for synthetic antibiotics

This study was designed to evaluate the effect of graded levels scent leaf meals on blood parameters and carcass characteristics among two broiler strains. A total 150 unsexed broilers consisting 75 Abor Acre Cobb were randomly allotted into 5 treatments 15 birds for each strain. Treatment one (T1) had no meal (control); treatment (T2), three (T3), four (T4) five (T5) 0.5%, 1.0%, 1.5%, 2.0% throughout experimental period (56days). Blood samples evaluated after feeding trial subjected analysis variance in a completely randomized design. Results revealed that diets strain significantly (P < 0.05) affected live weight, dressed weights, dressing percentages. T3 highest weight (2091.50 ± 85.27 g 1737.67 22.16 g), while T5 recorded lowest (1700 102.47 and1253.17 68.09 g). superior Arbor acre all traits except leg weight. Red Cell, White Mean Corpuscular Volume, Haemoglobin Count strains different, Pack Cell Haemoglobin, Neutrophils, Lymphocytes, Monocytes, Eosinphils Basophils not different > 0.05). detrimental test ingredients birds, though 1.5% inclusion rate could be tolerated, 1.0% is recommended optimum performance, can therefore efficiently replace synthetic antibiotic production.
