Endo-1,4-beta-xylanase with traces of endo-1,4-beta-glucanase improves the performance of weanling pigs supplied diets reduced in 90 kcal metabolisable energy/kg

This experiment was carried out to evaluate the effect of endo-1,4-beta-xylanase with traces of endo-1,4-beta-glucanase on the performance of 240 piglets (Landrace × Yorkshire × Duroc) with an initial body (BW) of 5.90 ± 0.6 kg. The mixed sex piglets were randomly assigned to 3 treatments with 10 replicates per treatment, and 8 heads per replicate pen. The dietary treatments include (1) corn-wheat-soybean meal (SBM) basal diet without xylanase (XYL) enzyme as positive control (PC), (2) corn-wheat-SBM diet deprived -90 kcal/kg metabolizable energy without XYL enzyme (NC), and (3) corn-wheat-SBM diet deprived -90 kcal/kg metabolizable energy + 0.02 XYL (DG2). The diets were administered in mash form for 42 d (split into 2 phases) as phase 1, d 0-21, and phase 2, d 22-42. All the experimental diets were designed to fulfil the nutrient requirement by NRC 2012. The results show XYL supplementation significantly increased (
