Effects of three types of inulin on dietary iron bioavailability and site of their disappearance in the digestive tract of young pigs.

Abstract

Inulin may be used to improve mineral nutrition in humans. We showed positive effects of Synergy 1, a mixture of short oligofructose P95 and long-chain HP (Orafti, Tienen, Belgium) on hemoglobin repletion efficiency (HRE) and cecum as the major degradation site in young anemic pigs. The present study was conducted to compare the effect of HP and P95, relative to Synergy 1, on HRE and their degradation site in weanling pigs. Thirty-two pigs (6-wk old) were individually housed and fed a corn-soybean meal based diet (BD) without supplemental inorganic iron, or the BD plus 4% of Synergy 1, HP, or P95 for 5 wk. Blood hemoglobin (Hb) concentrations were measured weekly. Daily feed intake and weekly body weight gain were recorded to calculate HRE. At wk 5, digesta samples were collected from lower jejunum, ileum, and cecum of pigs at slaughtering for inulin analysis. Blood Hb concentrations were 10% greater (P
