Zusammenfassung: | The animal production is a satisfactory index activity in the Amazon region. Ruminants are mainly kept on pastures cultivated, in soil of low fertility, submited to climatic stresses, with negative consequences on the availability and nutritional value of forage produced. In this aspect, technological innovations adjusted to the region will contribute to rise the productive standards of the cattle, by the intensification in the use of feed supplementation, with adapted leguminous. The Pueraria phaseoloides leguminous presents many advantages as a culture to intercalate, being distinguished as having better conservation of the ground, high production of green mass, high protein content of the leaf and other advantages. Thus, 'pueraria' is as an alternative for feed supplementation of ruminants, due to its forage potential. Key words: chemical composition, crude protein, digestibility, forage, intake. A pecuaria e uma atividade de indices produtivos satisfatorios na regiao amazonica. Entretanto, alguns ruminantes sao mantidos, na sua maioria, em pastagens implantadas em solos de baixa fertilidade, sujeitas a estresses climaticos, com reflexos negativos na disponibilidade e valor nutritivo da forragem produzida. Nesse aspecto, inovacoes tecnologicas adequadas a regiao, contribuirao para elevacao dos padroes produtivos, atraves da intensificacao no uso de suplementacao alimentar, com leguminosas adaptadas. A leguminosa Pueraria phaseoloides apresenta diversas vantagens como cultura intercalar, destacando-se: melhor conservacao do solo, alta producao de massa verde, alta concentracao de proteinas nas suas folhas, dentre outras. Assim, essa leguminosa desponta como alternativa na suplementacao alimentar de ruminantes, devido ao seu potencial forrageiro. Palavras-chave: composicao quimica, consumo, digestibilidade, forragem, proteina bruta. |
