NOTA T…CNICA Digestibilidadin vitro ileal y total de Morus alba L. yTrichanthera gigantea (H & B), como alimento para cerdos Ileal and totalin vitrodigestibility ofalba L. and Trichanthera gigantea (H& B) Nees,as feed for pigs

Studies were conducted mimicking mouth to ileum (in vitro, pepsin/pancreatin) and mouth to rectum ( in vitro, fecal) digestibility in four batches of mulberry (Morus alba L.) and tricantera ( Trichanthera gigantean (H & B) Nees) leaf meals used for feeding pigs. Mulberry and tricantera leaf meals contained on average, 31.5 and 50.5% cell wall and 22.19 and 21.88% of crude protein (Nx6.25) in dry basis, respectively. It was found that ileal, in vitro N digestibility was signi˚� cantly (P<0.001) higher in mulberry meal than in tricantera meal (45.0 and 35.0% respectively). Fecal,in vitro digestibility of organic matter was higher in mulberry than in tricantera meal (65.2 and 40.0% respectively.) Data of ileal,in vitro digestibility were associated to the N linked to cell wall, whereas fecal, in vitro digestibilities were related to production of short chain fatty acids (R 2 , 0.996; P<0.001).
