Resumo: The bovine production on pastures is a sustainable activity, responsible to generating income and employments in many tropical regions. However, in this system a major obstacle occurs during long dry periods, when the forages show low nutritional quality. In this research we evaluated the in vitro digestibility and degradability of Urochloa decumbens and Cynodon dactylons var Tiffton 85 inoculated with isolates of Aspergillus spp. from the gastrointestinal tract cattle. Four cows with rumen fistula were used as rumen contents donors to determine the in vitro digestibility of dry matter (IVDMD). The treatments were, as follows: control - No fungal inoculum, AT13 – (with Aspergillus terreus isolate), AF69 – (with Asperillus fumigates isolate, MIX (with mix of fungi AT13 and AF69). The analyses were performed in rumen simulator with four replications. The gas production was determined by semi-automatic method for both gas and the mechanics ability to fiber colonization of these fungi isolates were evaluated by scanning electron microscopy. The inclusion of AF69 and MIX promoted significant increase of IVDMD of U. decumbens (41.4 - 42.1%). The dry matter degradability were not influenced by the inoculums types using the by semi-automatic gas production method However, they linearly increased with fermentation time.  The two isolates of Aspergillus spp. were able to colonize the U. decumbens fiber showing production of mycelium and reproductive structures in electronic microscopic analyses. The addition these Aspergillus isolates promotes significant increase of IVDMD to U. decumbens, indicating promising potential for development of microbial or probiotic additive to cattle raised on lignified tropical pasture.

Sin embargo, en este sistema, un obstáculo se presenta durante los largos períodos de sequía, cuando los pastos tienen baja calidad nutricional. En esta investigación, la digestibilidad y degradabilidad in vitro de Urochloa decumbens y Cynodon dactylons var Tiffton 85 inoculados con Aspergillus spp. del tracto gastrointestinal bovino. Se utilizaron cuatro vacas con fístula ruminal como donantes de contenido ruminal para determinar la digestibilidad in vitro de materia seca (IVDMD). Los tratamientos fueron los siguientes: control- Sin inoculo de hongos, AT13 - (con  aislado Aspergillus terreus), AF69 - (con aislado Aspergillus fumigatus), MIX (con mezcla de hongos AT13 y AF69). Los análisis se realizaron en un simulador ruminal con cuatro repeticiones. La producción de gas se determinó mediante un método semiautomático para los ácidos grasos del rumen y la capacidad mecánica para la colonización de las fibras vegetales por estos hongos se evaluó mediante microscopía electrónica de barrido. La inclusión de hongos AF69 y MIX promovió aumento significativo de IVDMD de U. decumbens (41,4 - 42,1%). Los tipos de inculon no influyeron en la degradabilidad de la materia seca cuando se utilizó el método de producción de gas semiautomático. Sin embargo, aumentaron linealmente con el tiempo de fermentación. Los hungos pudieron colonizar fibras de U. decumbens, mostrando producción de micelio y estructuras reproductivas. La adición de estos aislados de hongos seleccionados promueve un aumento significativo de IVDMD para U. decumbens, lo que indica un potencial prometedor para el desarrollo sostenible de aditivo microbiano o probiótico para el ganado criado en pastos tropicales lignificados.A produção bovina em pastagem é uma atividade sustentável, responsável por gerar renda e empregos em diversas regiões tropicais. No entanto, neste sistema, um entrave o ocorre durante os longos períodos de seca, quando as pastagens apresentam baixa qualidade nutricional. Nesta pesquisa os objetivos foram avaliar a digestibilidade e degradabilidade in vitro de Urochloa decumbens e Cynodon dactylons var Tiffton 85 inoculados com isolados de Aspergillus spp. do trato gastrointestinal bovino. Quatro vacas com fístula ruminal foram utilizadas como doadoras de conteúdo ruminal para determinar a digestibilidade in vitro da matéria seca (IVDMD). Os tratamentos foram os seguintes: Controle- Sem inóculo fúngico (controle), AT13 – (com isolado Aspergillus terreus) , AF69 – (com isolado Asperillus fumigatus), MIX (com mix dos fungos AT13 e AF69). As análises foram realizadas em simulador ruminal com quatro repetições. A produção de gás foi determinada por método semi-automático para ácidos graxos do rumen e a capacidade mecânica de colonização das fibras vegetais por esses  fungos foi avaliada por microscopia eletrônica de varredura. A inclusão de fungos of AF69 and MIX promoveram aumento significativo de IVDMD de U. decumbens (41,4 - 42,1%). As degradabilidades da matéria seca não foram influenciadas pelos tipos de inoculantes, quando se utilizou o método de produção de gás semiautomático; entretanto, aumentaram linearmente em função do tempo de fermentação. Os dois isolados de Aspergillus spp. foram capazes de colonizar fibras de U. decumbens, mostrando produção de micélio e estruturas reprodutivas em análises de microscopia eletrônica. A adição desses isolados de fungos selecionados promove aumento significativo de IVDMD para U. decumbens, indicando potencial promissor para o desenvolvimento sustentável de aditivo microbiano ou probiótico para bovinos criados em pastagem tropical lignificada.
