In the conditions of the Republic of Belarus there was realized comparative evaluation of chemical composition and nutritive value of silages produced on the basis of millet (Panicum) and maize (Zea mays), their productive action and economic efficiency of ensilage fodders in diets of young stock of cattle. Data of chemical analysis showed the benefits of millet silage. The content of crude protein, crude fat, carotene, calcium and phosphorous was higher in millet silage. The analogous situation was in the analysis of biochemical indexes and energy value of dry matter. As a result of application of millet silage in diets of young stock of cattle made it possible to obtain 3,7 kg of body weight gain, while the expenses of forage per 1 kilogram of of weight gain lowered on 0,34 centner of fodder units, or 3,6%. Prime cost of 1 centner of fodder units in a diet in experimental group was on 57,3% lower than in a control one. Thus, use of millet silage in diets of heifers made it possible to lower the cost of fodders per 1 kilogram of weight gain on 63,2%, and prime cost of 1 kilogram of weight gain – on 19,8%.
