The evaluation of feed based on the productive effect of dry matter, crude protein and nonstructural carbohydrates in the production of milk was made. 1 kg of dry matter of leguminous-cereal mixtures in different phases of vegetation is taken as a unit of measurement for determining the productive effect of dairy products. The content of feed units in the flowering phase of the mixture is 0.2, while it is 0.19 in the phase of earing. The flowering phase gives more exchange energy and crude protein than the earing one by 14.3% and 12.9%, respectively. According to indicators of dry matter and crude protein per 1 kg of dry matter, the pasture grass with preference of Dactylis glomerata L. has the lowest productive effect and can be used only for feeding the low productivity cows or for grazing livestock. The leguminous-cereal mixtures in the flowering phase like clover-cereal, clover-lucerne, clover with timothy and aftergrass of clover with timothy are the best for low productivity cows, while the clover-cereal mixture and aftergrass of clover with timothy are good for high productivity cows.

The pasture grass with preference of Dactylis glomerata L. has the highest coefficient of fiber depressive action. The production of milk by the content of crude protein per 1 kg of dry matter of such feed is 0.4-0.3 kg. The clover and Dactylis glomerata L. in the flowering phase reduce the production of milk by the content of protein to 1.0-0.8 kg with a daily milk yield of 12-22 kg and a high productivity of 0.6-0.7 kg.

The clover-lucerne mixture provides 1.4-1.2 and 1.1-0.9 kg, respectively. In combination with timothy, it has a slightly lower milk production by the content of crude protein and a higher coefficient of fiber depressive action.

The aftergrass of clover with timothy has a high productive effect of 1.55-1.4 kg of milk by the content of protein for the cows with low yield and 1.3-1.0 kg for those with high yield.

The productive effect of voluminous feed in the production of milk is determined by the timing of harvesting grasses for hay and silage. Perennial legumes should be cut in the phase of budding, cereals – in the phase of the output into the tube and earing, vetch-cereal mixtures – at the beginning of the filling of beans.
