摘要
Ruminal fermentation of spineless Opuntia ficus indica f. inermis, OFI) and spiny (Opuntia amyclae, OA) Cactus cladodes and of diets including them was determined in glass syringes and single-flow continuous culture fermenters, respectively. The OR and CA chemical composition and gas production were similar. Two iso-nitrogenous and iso-energetic diets composed of barley straw, OFI (OFI-diet) or OA (OA-diet), Atriplex nummularia L, a mineral-vitamin mixture, and Urea were Supplied to four single-flow continuous culture fermenters, Digested carbohydrates (DCHO), volatile fatty acids (VFA) output and efficiency, non-ammonia (NAN) and bacterial N output and efficiency were similar (P>0.05) for OFI- and OA-diets. We conclude that OR and OA had similar nutritive Value. In vivo studies are needed to confirm current results. (c) 2008 Elsevier B.V. All rights reserved.
