ADDITIVES AND PREMISES USED TO OBTAIN HIGH QUALITY SILAGES

Resumen

Abstract: The use of additives in silages is increasing worldwide, based on the premise of the better material preservation or because of an aggregation of nutritional value with the use of some types of additives. This review aims to present information on a series of additives that can be used in a variety of silages according to their needs. The main classes of additives currently available are: fermentation inhibitors, nutrients, aerobic deterioration inhibitors, fermentation stimulants and humidity absorbent additives. It is fundamental that the properties adopt the practice of producing quality roughage as a primary investment, aiming on a greater financial return through the adoption of strategic planning in the short, medium and long term. There are several additives available in the market, but it is ideal to know if its use in the silage is necessary, what is the form of application, its dosage, and how the additive will benefit the silage. Thus,, it is essential the search for additives that gives additional contribution to the microorganisms responsible for the potentialization of the fermentation of the substrates present in the biomass, aiming to bring benefits to the fermentation process, to reduce losses, to stimulate or inhibit fermentations, to keep the stability of the forage, and to preserve the nutritive value of the ensiled mass in order to be similar to the green forage, or as close as possible to the plant it came from, or to add nutritional value through certain classes of additives.
