Abstract:
Background and Objective: In order to reduce high cost of feed which will step-down the cost of poultry products and encourage small scale and medium scale poultry production, efforts must be made by animal nutritionists to exploit and use some unconventional feed ingredients. Most of these unconventional feed ingredients such as brewer’s dried grain pose some threats (high fiber) with regards to their utilization by birds. Hence, the use of feed enzymes to reduce these threats for optimum productivity becomes necessary. The aim of the study was to determine the effect of different levels of enzyme fortified dried brewer’s grain (EDBG) on blood bio-markers, growth performance, carcass traits; and income over feed cost in a five week trial. Materials and Methods: A total of 300 day old non-sexed “Anak strain” chicks were randomly assigned to four dietary treatments with five replicates of 15 birds each. The treatments include, EDBG0, EDBG3, EDBG6 and EDBG9 for 0, 3, 6 and 9% levels of EDBG for both starter and finisher phases. Results: Growth traits for starter phase was better (p<0.05) for birds fed control (EDBG0) diet while birds fed EDBG3 recorded an improved (p<0.05) growth traits during the finisher phase of the feeding trial. Carcass yield, thigh, breast and drumstick weights of birds had the highest (p<0.05) values for birds fed EDBG3, while birds fed EDBG9 recorded the lowest (p<0.05) carcass, thigh, breast and drumstick weights. The blood bio-marker examination differ (p<0.05) among treatments for Eosinophil, Monocyte, Lymphocyte, White blood cell, Hemoglobin and Red blood cell. Hemoglobin concentration and RBC was highest (p<0.05) for birds fed EDBG0 and EDBG3. Birds fed EDBG3 recorded the highest (p<0.05) revenue from a bird produced and a better income over feed cost. Although, cost of total feed consumed was the highest for birds fed EDBG0 and EDBG3 but similar to those fed EDBG6. Conclusion: With regards to improved growth traits, improved cut yields and a better production cost as well as stable health status of broilers, 3% level of Enzyme fortified dried brewer's grain can be used safely.
