Effect of Using Corn DDGs Fortified with Xylanase and Mannanase Enzymes in Broiler Ration on Growth Performance, Nutrients Digestibility and Economics

IntroductionT he thriving global poultry industry demands a steady supply of nutrients, energy, proteins, essential amino acids, minerals, and vitamins to optimize bird performance and ensure smooth operation.Feed alone accounts for roughly 70% of production costs, posing a significant challenge in Abstract | Poultry feed often includes Distiller's Dried Grain with solubles (DDGS) as a source of protein and energy.However, DDGS is high in non-starch polysaccharides (NSPs), which can harm broiler performance and digestibility.This study aimed to counteract these negative effects by adding Xylanase and Mannanase enzymes to DDGS-based broiler feed, aiming to minimize the impact of NSPs and improve overall performance.The experiment involved 300 one-day-old chicks.After a one-week acclimation period, they were divided into five equally sized groups (D1 to D5).D1 served as the control group, receiving only the basal diet.The remaining groups (D2-D5) received feed containing 10% DDGS.Group D3 was supplemented with 1g/kg Xylanase, group D4 received 1g/kg Mannanase, and group D5 got a 2g/kg blend of both enzymes.All groups had access to feed and water freely throughout the 42-day trial.Results indicated that chicks fed with exogenous enzymes showed significant improvements (P
