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,

FIG. 83. Portable hog-houses with low, flat roofs; if used for housing swine in hot 

 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
