Contribuição ao estudo da composição química e digestibilidade do feno de siratro, Phaseolus stropurpureus

This paper deals with experiments carried out at the Bromatology Laboratory, E.S.A. "Luiz de Queiroz", USP, in order to assess the chemical composition and the digestion coefficients of siratro hay, Phaseolus atropurpureus. The field cured hay was analysed by standar methods usually employed, and two wethers were used in the digestibility trials. The results are summarised in tables I through II. Data from siratro hay were compared to those obtained with several tropical legumes used as hay. The nutritive value of siratro hay is discussed.
