It is determined that product net energy content in haylage and silage depends on metaboliizable energy concentration in dry matter of a feed: the more metabolizable energy is contained in feed, the more effectively it is spent in animal's organism. Averagely the metabolizable energy content in silage in 1 kg of dry matter is 9,1 MJ, product synthesis takes 2,35-3,56 MJ of it or 27-36%. Metabolizable energy concentration in silages averagely makes 9,26 MJ in 1 kg of dry matter. Product synthesis takes averagely 2,91 MJ or 31,3%
