2000. Comparative effects of legume protein sources on digestibility and small intestine morphology and function in weaned piglets.

Résumé : Two experiments were conducted to compare the digestibility of six legume seeds in piglets (Duroc x Landrace) weaned at 28d, and their impact on intestinal tissues sampled at slaughter. Total tract (TTAD) and ileal (IAD) apparent digestibilities were measured between 32-39 and 53-60d, respectively. The pigs were pair-fed a control (C) diet with casein as the sole protein source, or diets with half of CP supplied by soyabean meal (SBM), pea (P), faba bean (FB), or lupin (L) in experiment 1, and white or black chickpea (WCP, BCP) in experiment 2. TTAD of DM was the highest with C, SBM, P and WCP, and the lowest with L and BCP. The latter had the lowest TTAD of CP too. In experiment 1, IAD was the lowest with L for DM, and with SBM, P, FB and L for CP. IAD of DM and CP in experiment 2 were significantly lower (P< 0.001) with the WCP and BCP diets than with C, the difference between WCP and BCP diets being non significant. The diet impacted significantly on duodenal tissues. Villus height was the highest with SBM and the lowest with FB and BCP. Crypts were the widest with legume-containing diets. The villus/crypt ratio was the highest with C, and the lowest with P, FB, L, WCP and BCP. The legume diets depressed the duodenal activities of aminopeptidases A and N, lactase and alkaline phosphatase. To conclude, the legume-based diets had a reduced CP digestibility when compared to the control, but differences among them were moderate. Legumes affected the duodenum morphology and function.
