Elaboración de ensilaje a base de mezcla forrajera mediante la utilización de un coctel bacteriano.

Abstract

The objective of this research was to elaborate a silage based on a forage mixture (Penissetum purpureum and Gliricidia sepium) using a bacterial cocktail. This work was carried out at San Matteo farm located in Santo Domingo de los Tsáchilas province. A completely randomized design with a combinatorial arrangement of factors was applied: factor A, levels of bacterial cocktail, with T0 being the control treatment, T1 with 5% inclusion, T2 with 10% inclusion and T2 with 10% inclusion, T2 with 10% inclusion and T3 with 15% inclusion, while factor B corresponded to silage opening days 30, 45 and 60. The results were evaluated by analysis of variance (ADEVA) using the Tukey and Jollife statistical test. When the analyses were carried out, it was determined that the variables protein, fiber, ash, colony forming units, moisture, Ph, acidity and yield presented highly significant differences (p<0.01) according to the levels of bacterial cocktail with results of 8.86%, 36.53%, 12.39%, 293444.44 Ufc/g, 4.9, 79.73%, 55.66% and 99. 82% respectively, registering the best value in treatment T1 and the lowest value in T3, while the opening days, no significant differences were observed (p>0.05) except for fiber with highly significant differences (p<0.01) registering the highest value at 60 days with 30.33%. Therefore, implementing bacteria to silages is beneficial, and the opening days do not affect the nutritional content. It is recommended to use bacterial cocktails for a better result in the preparation of silage.
