The digestion of fibre in herbivorous Anatidae a review

摘要: Numerous studies on the ability of herbivorous Anatidae to digest fibre from a variety food types (foliage, seeds, tubers) have yielded variable results. Herbivorous ducks and geese capacity some components (between 0% 85%, depending study com ponents analysed), in particular hem icellulose. H em icellulose may be partially digested by acid hydrolysis early digestive tract, small particles fluid digesta obtained undergo lim ited ferm entation caecae (with aid symbiotic microflora).
