| description | ABSTRACT
The animal meal prohibition as a protein source with low ruminal degradability in ruminant nutrition, creates the need to seek alternatives, as legume seeds, however, its protein, have a high degradability, which could generate losses of nitrogen in the rumen. Other problem in the legume seeds is the content of antinutritional factors such as protease inhibitors, tannins, phenolic compounds, lectins and some others, could affect the digestibility. One alternative to decrease the degradability of the protein and / or decrease the activity of some antinutritional factors is the use of different technological treatments such as roasting. Microbial protein synthesis is dependent on the availability of nitrogen or amino acids and of the degradable carbohydrate content, or of content of Organic Matter digestible and rumen degraded (OMDRD), and the synchronization in rumen degradation between protein and carbohydrates. If there are high amounts of degradable nitrogen or if the content and rate of carbohydrates degradation in the rumen is reduced or not synchronized with the degradation of protein, could be losses of nitrogen and / or energy in the rumen. In this paper, we analyze the characteristics of proteins and carbohydrates from various seeds and grains, the effect of dry-roasted application on degradability behavior of seeds.
RESUMO - A proibição das farinhas de origem animal como fonte de proteína com baixa degradabilidade na nutrição de ruminantes, criou a necessidade de buscar alternativas, como sementes de leguminosas, porém, sua proteínas têm alta degradabilidade, podendo gerar perdas de nitrogênio no rúmen. Outro problema em sementes de leguminosas é o conteúdo de fatores antinutricionais, como os inibidores de proteases, taninos, compostos fenólicos, lectinas e alguns outros, podendo afetar a digestibilidade. Uma alternativa para diminuir a degradabilidade da proteína e/ou diminuir a atividade de alguns fatores antinutricionais é o uso de diferentes tratamentos tecnológicos, tal como a tostagem. A síntese de proteína microbiana é dependente da disponibilidade do nitrogênio e o conteúdo de carboidrato degradável, ou o conteúdo de matéria orgânica digestível e degradada no rúmen (MODR), e a sincronização da degradação no rúmen entre proteína e carboidratos. Se existem elevadas quantidades de nitrogênio degradável, ou se o conteúdo e a taxa de degradação de carboidratos no rúmen é reduzida ou não sincronizada com a degradação da proteína, pode-se perder nitrogênio e/ou energia do rúmen. Neste trabalho, foram analisadas as características das proteínas e carboidratos de várias sementes e grãos, o efeito da aplicação da tostagem seca no comportamento da degradabilidade das sementes. |
