310 PRODUCTIVE FEEDING OF FARM ANIMALS 
steers are fed protein feeds in addition to corn, they are able to digest 
the starchy components of the ration better than in case of wide 
nutritive ratios, and hogs, in that case, can glean less feed from the 
droppings. 
Fattening Rations.—When the ration of the steers consists of 
whole corn, the hogs are usually fed one-fourth to one-third pound of 
tankage per head daily; this will be all they need in addition to the 
corn in the droppings for about four to five weeks, until they do 
not apparently gain further in weight. They are then taken out 
and finished on a ration of corn and tankage, cotton-seed meal,

weather, they should be provided with a shade at the rear under which the pigs can lie in 
comfort. This shade is five feet wide, made of inch stuff placed upon removable supports 
which rest upon cleats nailed to the ends of the house. (Wisconsin Station.) 
peas, shorts, or gluten feed, in the proportion of seven parts of corn 
to one of tankage, or of three parts of corn to two parts of either of 
the other feeds. The fattening period ordinarily lasts about sixty 
days, at the end of which time the hogs will generally weigh about 
200 pounds. 
In other sections of the country hogs are either fattened on dif- 
ferent kinds of pasture and fed grain in‘ addition, or are fed in 
a dry lot until ready for the market. The latter method is less 
satisfactory for summer and fall feeding than pasturage, as it 
increases the cost of production, the hogs are less thrifty, and a 
larger amount of grain is required per 100 pounds gain. It is essen- 
tial to furnish some green feed, as clover, alfalfa, and corn. The
