Effects of dietary insoluble fibre supplementation on nutrient digestibility and livability in commercial broiler chicken

Abstract

This study conducted to assess the effects of dietary insoluble fibre supplementation on nutrient digestibility (retention) and livability in commercial broiler chickens. A total of 160 day-old Vencobb 430Y broiler chicks were randomly assigned to five treatment groups, each consisting of four replicates with eight birds per replicate. The level of supplementation of insoluble fibre was 0%, 0.25%, 0.50%, 0.75% and 1% resulting in treatments T1 (basal diet), T2 (basal diet + 0.25% insoluble fibre), T3 (basal diet + 0.50% insoluble fibre), T4 (basal diet + 0.75% insoluble fibre) and T5 (basal diet + 1% insoluble fibre) throughout the experimental period of 42 days. The results revealed that, retention of dry matter, organic matter, crude fat, crude fibre, NDF and ADL did not differ significantly among treatments. In contrast, ADF retention was significantly higher (p
