Fermentative and bromatological characteristics of Piata palisadegrass ensiled with levels of meals from biodiesel industry

The goal of this study was to evaluate the fermentative and bromatological characteristics of Piata palisadegrass (Brachiaria brizantha cv. Piata) ensiled with levels of meals from biodiesel industry. The experiment was performed at the Federal Institute of Goias State, Campus Rio Verde. The experiment was a completely randomized design with four replications, in 4 x 4 factorial arrangement, being four meals (cotton, sunflower, soybean, and canola) and four levels of inclusion (0, 5, 10 and 15%). The results showed the oleaginous meals from biodiesel industry are indicated as additives for ensiling Piata palisadegrass, by improving the qualitative, nutritional and fermentative characteristics of the Piata palisadegrass silage. It is recommended the addition of 15% of the meals, since this level provides the best quality of silage. The soybean meal is the most effective to improve the silage quality, in comparison with the other additives.
