The effects of high fibre(250 g kg-1dry matter (DM) total dietary fibre (TDF)) from different feeds on growth and slaughter
performance were investigated in pigs fed maize-soybean diets fortified with Roxazyme® G2. The added fibre sources were maize
(Zea mays) cobs (MC), soybean hulls (Glycine max)(SH), brewerâ??s (barley; Hordeum vulgare L) grains (BG), Lucerne (Medicago
sativa) hay (L) or wheat (Triticum aestivum) bran (WB). A standard diet (141 g kg-1 DM TDF) served as a control. Diets were mixed
in duplicate, and one mixture was fortified with 200 mg Roxazyme® G2 (RX) kg-1 feed. In vitro methods were used to estimate fibre
fermentability. The study used 72 intact Large White X Landrace, malepigs(32.0 ± 5.6 kg live weight). The diets were fed ad libitum
for 70 days in a complete randomized design with a 6X2 factorial arrangement of the treatments. Digestibility was estimated at 65-
70 kg LW using Cr2O3as the indigestible marker. Depending on the source, high fibre reduced (P<0.05) feed intake (BG and L), the
digestibility of organic matter (WB, BG, MC), protein (BG, MC, WB), fat (WB, L), phosphorus (BG), ash (MC, SH) and energy (all
fibres). Maize cobincreased (p<0.05) the feed: gain ratio. Lucerne reduced (P<0.05) daily gain and dressing % and, similar to WB,
increased (p<0.05) lean %. Roxazyme® G2 did not affectany of the measured parameters. The results supported a fermentable-fibre
approach to maintain nutrient digestibility on fibrous diets. Supplementation with Roxazyme® G2 was not justified.
