註釋Dietary fibre is a compound of feeds which is related with physical satiety of the gut when provided in huge quantities, for example with forage inclusion, as a total mixed ration (TMR). The aim of the present experiment was to analyse the effect of increasing amounts of forage, offered to culled sows, in relation to the voluntary feed intake and nutrient digestibility of the rations. Twelve culled sows (Landrace x Large white), ranging between 3 and 8 parities, were allocated in individual crates and distributed into 4 groups according to each sow live weight (LW). A 4x4 Latin square experimental arrangement was used to obtain the 4 different dietary treatments (according to Forage: Concentrate, proportions of DM; D1, 0:100; D2, 15:85; D3 30:70 and D4 45:55). Diets D2 to D4 were the experimental diets, and were offered ad libitum, while D1 was used as a control diet offered at 3kg/day. Forage fraction consisted of maize silage (55.4% DM), chopped straw (33.3% DM) and wet brewer's grains (11.2% DM). The concentrate feed was the same for all treatments, and a 0.5% of TiO2 was included as indigestible marker to calculate nutrient digestibility. As it was expected, voluntary feed intake was reduced according to the forage increase in the diet (5.88 vs 4.25 and 3.26 kg DM/day; p
