306 PRODUCTIVE FEEDING OF FARM ANIMALS 
quantity of pork produced from a given acreage, when hogged 
down, will be greater than when ear corn or snapped corn is fed 
in pens. 
Feeding the Boar.—The feeding of the boar should vary ac- 
cording to his age and the season of the year. Thin, growing boars 
need more grain than older ones, but neither should be fed so 
that they will grow fat, since this will impair their breeding 
qualities, just as much as having them in a thin body condi- 
tion. The boar should receive only as much grain as he will 
clean up readily, and should have a chance to exercise in summer 
time in a pasture lot, and in the wihter in a small yard adjoining 
the pen. Succulent feed should be provided throughout the year if 
possible: During the summer by pasturage or cut green feed, 
giving enough grain to maintain a good condition of flesh; during 
the winter months either roots, pumpkins, or culled fruit may be 
supplied. An allowance not over a pound daily of grain per 100 
pounds live weight will be sufficient while on the summer pasture, 
and during the winter, two pounds grain and four to six pounds 
roots. The grain should contain a considerable proportion of pro- 
tein, as, e.g., shorts and fine-ground oats (2 to lor 3 to 1). Skim 
milk is especially valuable for young boars as the breeding season 
approaches, and during this time two or three pounds grain may be 
fed; a mixture of equal parts of corn, ground oats, and middlings 
will prove an excellent combination. . 
Feeding the Sow and the Pigs.—The brood sow must be kept 
in a good body condition at all times, so far as possible, so as to be 
able to give birth to thrifty, vigorous pigs, and to furnish an abun- 
dance of milk for a healthy, rapid growth. Succulent feeds are 
an essential part of the ration both in summer and winter. A 
farrow, matured sow will keep in good condition on good clover 
or alfalfa pasture alone, but a young sow must receive about one 
to two pounds of grain daily per 100 pounds weight in addition; 
e.g., a mixture of oats or barley and shorts, with a little corn so as 
to keep the nutritive ratio down to about 1 to 6 (p. 294). But little 
grain is fed for a few days before farrowing, and the sow is given 
cooling feeds of a laxative nature, as roots, and a slop made up 
largely of bran or shorts. For the first twenty-four hours after 
farrowing no feed is given, but all the lukewarm water she will 
drink ; she is then given limited feed for three or four days, and is 
slowly brought up to full feed in the course of about ten days. A 
grain mixture of ground,corn, ground oats, and shorts (1:1: 2), 
mixed with three to five pounds skim milk, will give excellent re-
