Fig. 25. — Corn constitutes probably 95 per cent or more of the acreage of crops cut 

 for silage. In the Southwest relatively small amounts of kaflr and milo are used for 

 silage; and in the Northwest occasionally sunflowers are so used, likewise pea vines in 

 Wisconsin ; but the amounts, except of kaflr and milo, are insignificant. Silage is fed 

 principally to dairy cows in the winter, but its use for beef cattle is increasing rapidly, 

 especially in the Corn Belt, and a small amount is fed to sheep. Consequently at 

 present the area of silage crops corresponds in a general way with that Qf dairy cows, 

 except in central Kansas, where silage is fed mostly to beef cattle. (See Figs. 81 and 82.)

ACREAGE AND YIELD PER ACRE, 1919 



Fig. 26. — Corn is cut for forage mostly around the margin of the Corn Belt and in 

 the Middle and South Atlantic States. This practice corresponds, in a general way, 

 with the areas in which corn is cut and shocked. Doubtless much, perhaps most, of 

 this corn reported to the census as cut for forage was also harvested for grain. Much 

 of the acreage of corn shown on this map, therefore, is also shown on the map of corn 

 for gram (Fig. 24). The Department of Agriculture estimates tbe area of corn cut 

 for forage only in 1921 at 2,600,000 acres. Corn forage is fed almost wholly to cattlo, 

 though a little is used to feed sheep and horses.
