spring pigs may be given the range of the fields. Thus 
they will gather a considerable portion of their food. 
But they should not be denied additional food in the way 
of slops or of dry grain. Corn or corn and oil meal, or 
corn and tankage, may be used in combination to insure 
steady growth. Spring pigs thus raised, by July will be 
of fair growth. From this time they should be pushed 
somewhat in order that they may be fat by late fall or 
early winter. 
The feeding of green corn on pasture is common and has much 
in its favor. Practically all of the plant but the coarse stalk is con- 
sumed. The kinds of forage cover a wide range. The fact is, 
anything green that is appetizing is good for hogs. 
12, Fattening hogs.—The aim should be to get flesh 
growth rather than an overburden of fat. At the begin- 
ning of the fattening period hogs will eat 40 to 50 
pounds of dry matter per 100 pounds of live weight. 
This diminishes to 25 or 30 pounds as the fattening 
period advances. Hogs will get fat when on corn. 
Their best development is obtained when other feeds 
containing more protein are provided in addition. 
Tankage, peas, or beans are excellent. Use one part of 
either to eight or ten parts of corn at the beginning of 
the finishing period. 
The most intensive fattening is secured on easily digestible ma- 
terial. Corn is the universal food and enters most largely into the 
grain combination. All other grain feeds are to be used as supple- 
ments and as balancing foods with corn. During the beginning pe- 
riod of fattening when clover, alfalfa, or other pasture is available,
