Physical and chemical characterization of the fibrous fraction of five varieties of Vigna unguiculata foliage meal for monogastric animals

Five varieties of Vigna unguiculata meal were selected according to a compl etely randomized design to study the chemical composition and physical prop erties of the Fibrous fraction. Three grouped maturity varieties (INIFAT 93 , Cubanita 666 and Tropico 782) and two non-grouped maturity varieties (Vin ales 144A and Habana 82) were studied Both the Fibrous fractions, the neutr al detergent fibre (NDF), acid detergent fibre (ADP), lignin, cellulose and hemicellulose as well as the physical properties (solubility, volume and R ater absorption capacity) differed between varieties (P < 0.001). INIFAT 93 evidenced the greatest digestive potential given by the lowest cell wall ( NDF) and lignin content. Similarly this variety showed a higher fibrous fra ction solubility and the lowest packed volume. Results suggest a better nut ritional quality of the fibrous fraction of INIFAT 93 variety, although thi s must be confirmed through digestibility studies.
