Addition of a xylanase enzyme complex to a corn-based diet influences gut morphology in newly weaned pigs

摘要

Enzyme complexes are a common inclusion in feeds for young and newly weaned pigs to assist an immature digestive system. Multi-carbohydrases supplements have been reported to increase ileal dry matter (DM) and non-starch polysaccharide (NSP) digestibilities in young pigs (Kiarie et al, 2007). Supplementation with multicarbohydrases increases the low molecular weight fibre that may serve as substrates for residual microorganisms, which then may influence the intestinal structure. This study examined features of gut morphology following the introduction of a xylanase-based enzyme formulation in a corn-soy based ration for young pigs. The hypothesis tested was that weaner pigs fed a diet with multicarbohydrases will better maintain the intestinal structure than pigs fed a diet without multi-carbohydrases in the first 18 d after weaning
