Abstract
The purpose. To evaluate productive action of grain of corn in composition of silo, wet-preserved and dry, in feeding cows. Methods. ln the 1-st experience com silo was substituted with vetch-oat with addition of dry grain equivalent to its content in com silage, and in the 2-nd - they substituted dry grain of com in a ration with wet-preserved one. Results. Productive action of grain of corn in silo was for 10% lower tha.n of dry and for 5% lower than for wet-preserved at feeding highly productive cows. ln silo-concentrated rations energy value of silo is revaluated, as they do not consider necessity in energy of microorganisms of a rumen. Concluslons. The technique of preserving whole wet grain of corn has advantages in comparison with its silage making in the levigated kind. Therefore it is perspective in conditions of industrial milk complexes.

Key words: corn silo, wet grain of com, vetch-oat silo, milk cows, milk productivity.
