Composición química y digestibilidad in vitro del pasto saboya con diferentes niveles de palmiste

The objective of this research was to evaluate the chemical composition and in vitro digestibility of Savoy grass with different levels of Palm Kernel. A completely randomized design (DCA) was used with 4 treatments, T0: 0 g of palm kernel; T1: 50 g of palm kernel; T2: 10 g of palm kernel and T3: 15 g of palm kernel. The variables were analyzed according to the design used using the InfoStat statistical program. Comparison of means using the Tukey test to determine the difference between treatments. The laboratory work was carried out at the “La María” Experimental Campus of the State Technical University of Quevedo (UTEQ) located at km. 7.5 via Quevedo - el Empalme, Mocache canton, where the chemical composition and in-vitro rumen degradability of dry matter (DIMS) were evaluated at eight incubation times (0, 3, 6, 12, 24, 48, 72 and 96) hours. The total dry matter (DM) content showed a positive effect of the inclusion of Palm Kernel, with the highest percentages being recorded in T4 (28.61%) and T3 (27.97%), exceeding the control treatment T1 by 13.0% and 10.3% respectively. (25.36%), which allows us to infer that the addition of Palm Kernel improves the DM concentration of the forage, probably due to its high contribution of soluble carbohydrates and low humidity. Similarly, for organic matter (OM), the highest content was obtained in T4 with 88.06%, exceeding T1 (85.93%) by 2.5%, demonstrating that increasing levels of Palm Kernel increase (P<0.01). The percentage of inorganic matter (IM), registering in T4 a content of 11.94% versus 14.07% in T1. The DRIVMS found statistically significant differences (P<0.05 and P<0.01) for most variables. Specifically, in the first hours of incubation (0 to 6 h) the control treatment T1 (Savoy grass alone) presented greater degradability (P<0.05) compared to T2, T3 and T4. For effective degradability at fixed transit times of 2, 5 and 8% per hour, treatments T2, T3 and T4 greatly exceeded (P < 0.01) grass only T1, with increases of 3.6, 5.6 and 2.3 percentage points respectively. 8% per hour. This confirms the better ruminal use of the Palmiste grass.
