Proceedings... Sarasota, Florida: U.S. Agricultural Experiment Stations, 1978. p. 49-64.c1978  aThe objectives of model development were: 1) to determine if current theories of digestion, passage and particle size reduction could bedescribed adequately by mathematical equations and combined into a model to estimate fiber disappearance from the digestive tract; 2) to identify aspects of ruminant digestion and forage characterization wherecurrent concepts or data are inadequate; and 3) to test hypotheses regarding plant and animal factors influencing forage quality.  aForage  aMathematical models  aRuminant nutrition  aModelo Matemático  aNutrição  aPastagem  aRuminante1 aELY, L.
