Either corn silage or soiling crops will enable the dairy farmer to get an economical production of milk from his herd in summer when pastures are dried out, and he can maintain the level of production with one as well as the other. However, he must feed 75 percent more soiling crops, in weight, than silage, and his soiling crops should not cost him more than $4 per ton when silage costs $7 per ton. Generally speaking, corn silage is the more economical of the two feeds when the price of corn is low.

These conclusions appear as the result of work with the dairy herd at the Iowa Agricultural Experiment Station in the summers of 1918 and 1919.
