1. âAvaliaÃÃo morfolÃgica do abomaso e ceco-cÃlon de bovinosâ / Morphologic evaluation of abomasum and cecum-colon of bovines
The morphophysiology related to volatile fatty acids (VFA) absorption throughout the gastrointestinal tract of ruminants is not totally characterized. The elucidation of VFA behavior in all production and absorption sites can contribute to the adoption of nutritional strategies aiming to maximize food utilization and to reduce the occurrence of digestive dis

2. Rumen morphometrics and the effect of digesta pH and volume on volatile fatty acid absorption / Morfometria ruminal e efeito do pH e do volume da digesta sobre a absorÃÃo de Ãcidos graxos volÃteis
Os efeitos do volume e do pH da digesta sobre a absorÃÃo de Ãcidos graxos volÃteis (AGV) e sua correlaÃÃo com a morfologia da parede ruminal foram avaliados. Nove vacas fistuladas formaram trÃs condiÃÃes. âAltoâ, com vacas Holandesas produzindo 25,9 kg/d de leite e alimentadas com Dieta Completa rica em grÃos. âMÃdioâ, com vacas Girolando prod

3. AvaliaÃÃo morfofisiolÃgica da absorÃÃo e metabolizaÃÃo de Ãcidos graxos volÃteis pelo proventrÃculo de bovinos. / Morphophysiologic evaluation of the absorption and metabolism of volatile fatty acids by bovine forestomach.
About 60% of volatile fatty acids (VFA) produced in reticulorumen are absorbed in this compartment. The other 40% pass with the fluid phase to the omasum and are absorbed before entering the duodenum. Two experiments were carried out to determine the absorption surfaces and the VFA absorption and metabolism capacity of the bovine forestomach compartments. In
