The aim of this study was to evaluate the quality, bromatological and in vitro fermentation characteristics of ripe mango silage between 28 and 168 days of lactic fermentation (LF). The silos in bags (20 kg) were made with 80.64% mango, 11.38% pangola grass, 4.55% corn stubble, 2.04% molasses and 1.36% urea. The opening time of the silos was at 28 (T1), 44 (T2), 97 (T3), 113 (T4), 126 (T5), 140 (T6), 154 (T7) and 168 (T8) d of LF. It was determined pH, lactic acid, dry matter (DM), crude protein (CP), neutral detergent fibre (NDF), acid detergent fibre (ADF), hemicellulose, biogas and methane (CH4) production, ammoniacal nitrogen (N-NH3), pH of the medium, total bacteria count, dry matter degradation (DMD) and neutral detergent fibre degradation (NDFD). The statistical analysis was under a completely randomized design. Th...

The objective was to evaluate the fermentation kinetics and the in vitro degradation of the physiological parts of three native legumes of the municipality of Cuajinicuilapa, Guerrero. The substrates were pods, leaves and complete plant of centrosema (Centrosema plumiere), bean (Phaseolus lunatus var. silvester) and bean-tamarind (Phaseolus lunatus). The biodigestor contained 0.5 g of a substrate and 50 ml of culture medium. The biodigestor were incubated in a water bath at 39 °C for 72 h. Gas production was measured at 0, 2, 4, 6, 9, 12, 24, 36, 48 and 72 h. The gas production was used to obtain the parameters maximum volume (mV), rate of gas production (S) and time lag (λ). Dry matter degradation (DEGDM) and degradation of the neutral detergent fibre (DEGNDF) were determined by weight difference. The statistical analysis was a completely randomized design within a 3x3 factorial arran...

El objetivo del estudio fue evaluar la cinética de fermentación y la degradación in vitro de tres leguminosas nativas del municipio de Cuajinicuilapa, Guerrero. Los sustratos fueron vainas, hojas y planta completa de centrosema (Centrosema plumiere), frijolillo (Phaseolus lunatus var. silvester) y frijolillo-tamarindo (Phaseolus lunatus). Los biodigestores contenían 0.5 g de un sustrato y 50 ml de medio de cultivo. Los biodigestores se incubaron en baño maría a 39 °C por 72 h. La producción de gas se midió a las 0, 2, 4, 6, 9, 12, 24, 36, 48 y 72 h. La producción de gas se usó para obtener los parámetros volumen máximo (Vm), tasa de producción de gas (S) y tiempo lag (λ). La degradación de la materia seca (DEGMS) y degradación de la fibra detergente neutra (DEGFDN) se determinaron por diferencia de peso. El análisis estadístico fue un diseño completamente al azar con ...
