Use of vinasse as an additive in corn silage

This paper aimed to evaluate the use of doses of vinasse as an additive in corn silage and its effect on the bromatological and mineral composition, as well as food safety aspects of the silage. This research employed a completely randomized design with five treatments (doses of 0, 2.5, 5, 7.5, and 10% of vinasse on the weight of the mass per silo) and five replications, totaling 25 experimental units. The weight of the ensiled material decreased over the fermentation period, regardless of the vinasse dose. The 2.5% dose of vinasse increased the crude protein content by 16%, as well as the mineral matter, lead, potassium, and iron content of the corn silage. Thus, adding 2.5% of vinasse to corn silage promotes greater fermentation efficiency, improves bromatology, and enhances mineralogy while preserving the silage’s visual quality.
