Investigations in the conditions of Belarus Poozerye revealed the advantages of corn production compared to lucerne. As for the concentration of crude protein quite inverse dependence was observed: for lucerne this index changed within limits of 19.6-20.7 centner per ha, for corn 18.4-18.7 centner per ha. It was found that to reach balance in digestible protein of green materials of corn with productivity 194 centner per ha c.un.,it is required above two hectares of lucerne planting with crop yield level of 86 centner per ha of c.un. Comparative analysis has also shown that corn is better to be fed to dairy cows. At this, cost-efficiency reaches 21.7-38.1 %. And on the contrary, feeding of cattle stock by corn appeared to be loss making. In summing up expenses and earnings from milk and meat realization, cost-efficiency changes within limits of 1.1-15.1%
