Adotou-se o delineamento experimental inteiramente casualizado, num arranjo fatorial 4 × 5, com três repetições. Os dados foram submetidos à análise multivariada. O feno tratado com uréia apresentou a menor proporção de tecidos remanescentes após a digestão in vitro. Os tecidos que tiveram a degradação mais afetada pela amonização foram a bainha do feixe vascular e o esclerênquima. O feno tratado com 80 g uréia/kg MS e submetido à digestão in vitro por 24 ou 72 horas apresentou a menor proporção de tecidos com parede celular espessa e lignificada, como bainha do feixe vascular e esclerênquima. O tratamento com uréia também reduziu o tempo necessário para degradação dos tecidos foliares. O feno tratado com uréia e submetido a 12 horas de digestão apresentou a mesma proporção de tecidos que o feno não-tratado e submetido a 24 ou 72 horas de digestão in vitro. A epiderme e o tecido vascular lignificado apresentaram menor degradação após a digestão in vitro. Os resultados indicaram que o tratamento com uréia contribuiu para a desestruturação da parede celular, aumentando a degradação microbiana dos tecidos e reduzindo o tempo necessário para a sua digestão.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2011-10-03T15:39:34Z No. of bitstreams: 1 v39n8a27.pdf: 527752 bytes, checksum: 4e89477f958ec9ad991cad673407300a (MD5)Made available in DSpace on 2011-10-03T15:39:34Z (GMT).
