摘要：
Background: Researchers are challenged with identification of possible feed additives with the ability to increase the efficiency of feed utilization. Aims: The present work aimed at studying growth pattern and carcass traits in broiler fed on dietary enzymes (Enzymex) and probiotic (Yeamark) over a period of six weeks. Methods: A completely randomized design, including 8 treatments, 3 replications and 15 birds in each experimental unit was applied. Results: The results showed that feed intake decreased significantly (P<0.05) which might be due to the birds fulfilling their nutrient requirements by taking less amount of feed with improved digestibility of energy sources and amino acids. The results of present study also demonstrate the beneficial effects on performance and dressed yield in the treated groups in broiler. Conclusion: Enzymes and probiotic are, therefore, suggested to be used as feed additives in broiler rations for higher profitability.
