The aim of the study was to investigate the effect of faba bean treatment on content of ANFs and in situ ruminal degradability. Six ruminally fistulated sheep were divided in 3 groups and fed one of the following diets containing grounded faba bean according to a replicated Latin square design: (C) raw, as control; (B) soaked for 16 hours and (M) micronized. Both treatments don’t produced substantial reductions on polyphenols and tannins concentrations (range 4,20-11,88%). On the contrary, phytates, vicine and convicine were reduced mainly by soaking while antitrypsin factor by micronizing. The last treatment showed also the higher ruminal degradability of DM (61,00% C, 61,12% B, 72,85% M), probably as result of starch gelatinization, and the lower effect on protein ruminal degradability (thermal protein denaturation: 76,83% C, 74,22% B, 53,19% M).

Abstract
The aim of the study was to investigate the effect of faba bean treatment on content of ANFs and in situ ruminal degradability. Six ruminally fistulated sheep were divided in 3 groups and fed one of the following diets containing grounded faba bean according to a replicated Latin square design: (C) raw, as control; (B) soaked for 16 hours and (M) micronized. Both treatments don’t produced substantial reductions on polyphenols and tannins concentrations (range 4,20-11,88%). On the contrary, phytates, vicine and convicine were reduced mainly by soaking while antitrypsin factor by micronizing. The last treatment showed also the higher ruminal degradability of DM (61,00% C, 61,12% B, 72,85% M), probably as result of starch gelatinization, and the lower effect on protein ruminal degradability (thermal protein denaturation: 76,83% C, 74,22% B, 53,19% M).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
