Abstract: In vitro experiments were conducted using a three-step process to assess the enzymatic hydrolysis (pepsine and pancreatin) and fermentation capacity of Southeast Asian fibre-rich feedstuffs. The fibre-rich feedstuffs used were Banana stem (Musa acuminata) (Bas), Brewery by-product (Brew), Cassava (Manihot esculenta) leaf (CL) and root by-product (CR), Cabbage waste (Brassica oleracea) (Caw), Sweet potato vines (Ipomoea batatas) (Swe), Taro leaves and petioles (Colocasia esculenta) (Taro), Tofu by-product (TF), and Trichanthera gigantean (Tri). Tri and TF were marginally (10%) digested in the small intestine, which for TF was largely compensated at the level of the hindgut, resulting in the highest VFA production from TF as compared with any other fibre-rich feedstuff tested. Nevertheless, 55% of the CP of TF was digested in the small intestine, resulting in a modest accumulation of hindgut ammonia as compared with CP from Tri which particularly seemed to be fermented in the hindgut. Ammonia associated with Taro was somewhat lower as 62% of its CP was digested in the small intestine. For the complete diets, IDCP of the test diets was 7.8 to 18.5% lower than the Control diet, except for the TF diet. Only diets, including Bas and CL, enhanced hindgut VFA production compared with the Control. In conclusion, fibre-rich feedstuffs differ widely in intestinal digestibility and hindgut fermentation. Moreover, ileal CP digestibility of complete diets containing such fibre-rich feedstuffs might be lower as compared with the expected values calculated from individual ingredients.
