Effect of supplementation combination of phenolic aromatic polymer and modified lignin on growth performance in broilers

Abstract

An experiment was conducted to study the effect of phenolic aromatic polymer and modified lignin on growth performance 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) [4] standards, 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 both control and reformulated diets, respectively and T5 and T6 supplemented with 0.3% phenolic aromatic polymer and modified lignin in both control and reformulated diets, respectively. The results showed that birds supplemented with 0.2 and 0.3% phenolic aromatic polymer and modified lignin in control showed significantly improved body weight and feed conversion ratio compared to both the control and reformulated diets fed groups and no significant difference was noticed in feed intake and survivability among all the groups. It was concluded that supplementing phenolic aromatic polymer and modified lignin improved growth performance in broilers.
