The effectiveness of fatteners` diet supplementation with three levels of inulin (10, 20 and 30 g/kg mixture) obtained from water or water-alcohol extraction was assessed. The studies
included 140 crossbred pigs (PL × PLW) × Duroc of 25 ±0.5 kg initial body weight. The animals were assigned into 7 treatment groups, whose diets, besides the control, comprised different contents of inulin (10, 20 and 30 g) as water extracts (II, III and IV) or water-alcohol extracts (V, VI, VII). Fatteners’ performance, carcass traits and nutrient digestibility were evaluated during two fattening periods (grower and finisher) as well as at slaughter. Dietary inclusion of 20 g waterextracted inulin or 30g water-alcohol extracts improved the daily weight gain throughout the whole fattening period (p ≤ 0.05). The fatteners from these groups showed the best feed conversion, too. Generally, no significant correlations were reported between the extraction method and the studied traits, whereas a different inulin level affected the daily weight gain, feed intake or crude fiber digestibility.
