In the conditions of the Republic of Belarus there was realized determination of content of metabolizable energy and net energy in herbal fodders for cattle. In the article there was presented chemical composition of studied fodders. Also there were presented results of values of metabolizable energy and net energy in the analyzed herbal fodders. Net energy content of products in feeds depends on concentration of metabolizable energy in dry matter of feeds. The more metabolizable energy in the feed the more effective it is spent in animal's organism. On average within silages the metabolizable energy content in 1 kg of dry matter makes 9,1 MJ, net energy of products - 2,35-35,6 MJ or 27-36%. Metabolizable energy concentration on average within silages makes 9,26 MJ in 1 kg of dry matter. For products synthesis 2,91 MJ or 31,3% is spent on average. The best one with this index is rye silage - 34,6%.
