Silage is the product of the fermentation of different crops caused mainly by lactic acid bacteria (LAB) based on the acidification of the material under anaerobic conditions.
Biological silage additives are used in two main directions: a) to enhance the fermentation (homofermentative LAB producing mainly lactic acid) = stimulants; and b) to lengthen the aerobic stability of the silage in the feed out phase (under exposure to air, heterofermentative bacteria producing acetic or propionic acid) = inhibitors.
But in terms of profitability, are silage inoculants really interesting for the producer? How can its profitability be measured? The article's calculations are based on the improvement of the energy content in silage compared with non-treated silage.
