PRODUCTION AND EVALUATION OF FEED CONCENTRATE MADE FROM SUGAR CANE (Saccharum spp.) AND FERMENTED CHICKEN DROPPINGS IN SOLID STATE

Abstract

The effect of the inclusion of different levels of chicken droppings (chicken manure) on the nutritional value of a fermented feed concentrate in solid stage made of sugar cane (Saccharum spp.) was evaluated. Four levels of chicken droppings (0, 20, 30 and 40%) were evaluated, and five fermentation times in the solid stage (0, 24, 48, 72 and 96 h) with fourrepetitions in a completely random design with factorial arrangement. The content of dry matter (DM), raw protein (RP), actual protein (AP), neutral detergent fiber (NDF), in situ degradation of dry matter (DIMS), and fermentative parameters (pH, temperature, Brix degrees, reducing sugars, ammonia, lactic acid), and volatile fatty acids (VFAs) were determined. The DM (40% to 49.4%), the RP (14.7% to 22.5%), the AP (7.3% to 12.6%), the DIMS (56.8% to 67.8%) increased (P<0.05) from the effect of inclusion of the chicken droppings on the control treatment. The best results were the treatments with 20 % and 30 % of chicken droppings. At 24 h the best nutritional and fermentative parameters were found, concluding that the addition of chicken droppings to sugar cane allows obtaining a fermented food with good nutritional value for ruminants
