Abstract: An experiment was conducted to study the effect of phenolic aromatic polymer and modified lignin on gut health in broilers. Six treatment groups with three replicates of ten birds each for 42 days. T1 was fed with control diet based on BIS (2007) [3], T2 fed with reformulated diet with 2% reduction in metabolizable energy and crude protein of control diet, T3 and T4 supplemented with 0.2% phenolic aromatic polymer and modified lignin in control and reformulated diets, respectively and T5 and T6 supplemented with 0.3% phenolic aromatic polymer and modified lignin in control and reformulated diets, respectively. The results showed, birds supplemented with 0.2 and 0.3% phenolic aromatic polymer and modified lignin in control diet showed significant improvement in gut health compared to control and reformulated diets fed groups. It was concluded that supplementing phenolic aromatic polymer and modified lignin improved gut health in broilers.
