Agregar Etiqueta | Sumario: | Degradation of the King Grass grass silage (Pennisetum purpureum) with increasing levels of passion fruit husk (Passiflora edulis). Five treatments (100% King Grass, 90% King Grass + 10% passion fruit, 80% King Grass + 20% passion fruit, 70% King Grass + 30% passion fruit, 60% King Grass + 40% passion fruit) and four repetitions were used. Degradability and kinetics of dry matter (MS) were evaluated. The research was conducted in the Laboratory of Rumiology, Experimental Campus "La María". The in vitro degradability of dry matter (DIVMS) had close values of ruminal degradation from 6 hours to 72 hours, with an average of 50.29%, being higher (p <0.05) than the control based on 100% P grass purpureum In the degradation kinetics they express the effective degradability transit, it was superior for treatments with decreasing inclusion of king grass (90, 80, 70, 60%) and increasing levels of passion fruit husk (10, 20, 30 and 40% ) for T2, T3, T4 and T5 with values of 34.60; 34.12; 37.47 and 33.33%, respectively, followed by the 100% king Grass witness. The degradability of dry matter was higher in all treatments T2 (90% KG + 10% CM), T3 (80% KG + 20% CM) and T4 (70% KG + 30% CM), indicating high nutritional values being, an efficient and environmentally acceptable way of having food to sustain the productivity of ruminants in the dry season, with the exception of T1 (100% KG) and T5 (60% KG + 40% CM) that were lower. The kinetics of in vitro degradation and the ruminal passage of the nutritional fractions of the MS determined better efficiency for treatments T2, T3, T4 and T5 based on King Grass grass with passion fruit husk residues, being statistically higher than T1 (100% King Grass Grass).
