Abstract: An experiment was conducted to study the influence of different levels of Brewers Spent Grain (BSG) and Enzyme Supplementation (ES) in the diet on the productive performance and digesta viscosity of broilers from 7-42 day of age. Six treatments were arranged factorially with 3 levels of BSG (none, 7.5 and 15%), unsupplemented and supplemented with 0.05% enzyme. Treatments were formulated with the same AMEn and protein. Each treatment was replicated four times (consist of 12 chicks per replicate). During the experimental period daily weight gain, feed conversion and feed intake evaluated. At 21 and 42 days one bird from each replicate killed for measuring digesta viscosity. The results indicated a significant reduction in weight gain, feed intake and increase in feed conversion in broilers by feeding 15% BSG at during the starter period in comparison of control group (p<0.05). ES improved body weight, feed intake and daily weight gain in starter period (p<0.05). Digesta viscosity in broilers decreased with feeding 15% BSG in starter period (p<0.05). It was concluded that broiler performance is improved by ES at early ages. Also, BSG may be used up to 7.5 and 15% of the diets of broilers at starter and grower period, respectively.
