Andean valley of Abancay is used the pisonay (Erythrina sp.) as green fodder to supplement in the dry season. It was evaluated the chemical composition, ruminal degradability and parameters ruminal kinetics of dry mater (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose (HEM) and cellulose (CEL) at 120 and 365 days regrowth of the pisonay. A 5-year Holstein dry cow was used, with a live weight of 600 kg and permanent ruminal cannula. Samples of 5 g of each age of regrowth / nylon bag were incubated at 0, 3, 6, 12, 24 and 48 hours. The parameters of the ruminal kinetics were determined using the RUMENAL procedure, SOLVER function. The nutritional composition at 120 days was higher in the CP, FDA and CEL and at 365 days the DM, NDF and HEM. DM, NDF and ADF at 120 days of regrowth were higher than 365 days in the degradable fraction and effec...

Para considerar la inclusión de forrajes en dietas de rumiantes, es necesario conocer el valor nutricional y la calidad de los forrajes, en el valle interandino de Abancay tenemos la especie forrajera arbórea conocida como pisonay (Erythrina sp), que los criadores de ganado vacuno lechero, ganado caprino y de animales menores (cuyes) utilizan como principal forraje verde para suplemento en la época seca, para mejorar el consumo y utilización de alimentos voluminosos, en base al conocimiento tradicional; por lo tanto, se evaluó la composición química y los parámetros de la cinética ruminal in situ de la Materia Seca (MS) y Proteína Cruda (PC) del forraje de pisonay a los 120 y 365 días de rebrote. Se tomaron muestras de pisonay a los 120 y 365 días de rebrote. Para estimar la degradabilidad in situ de la MS y PC se consideró 0, 3, 6, 12, 24, y 48 horas de incubación, se incu...
