Response of broilers to dietary inclusions of different insoluble fibre sources in a reduced crude protein diet

Abstract

<p>Recent studies have shown that the decreased performance of broilers associated with feeding a reduced crude protein (RCP) diet cannot be fully recovered by supplementing essential amino acids (Hilliar et al., 2019). We hypothesized that the dietary inclusion of moderate amounts of insoluble fibre would improve gizzard function and protein/amino acid digestibility that could help to restore the performance loss associated with feeding a RCP diet. This study investigated the effects of oat hulls, soy hulls, sugarcane bagasse or lignocellulose based product as insoluble fibre sources in a RCP diet fed to broilers.</p>
