 ration. 



Effect on Habit. — The pig will eat feed largely in ac- 

 cordance with the way he is trained. As, for instance, a 

 pig that is fed upon nothing but slop during the early part 

 of his life, when changed to dry or whole grain, will not 

 eat it immediately. Pigs that have been accustomed to 

 certain definite feeds will not relish and may not eat for 

 a time new feeds that may be given them. Thus if pigs 

 are fed on corn, barley and skim milk for a time, soy 

 beans when added will not be relished by them and the 

 ration will not be eaten as readily, will not be as thor- 

 oughly digested, and will not produce the results that it 

 should. Therefore, a pig may be thrown off feed on a 

 total quantity that is less than he ought to consume to 

 the best advantage, and less than he will consume later 

 after he has become accustomed to the new feed. 



Thus the amounts of the various kinds of feeds that 

 are to be eaten by a pig, or the kinds of feeds that will be 

 eaten at all, are largely a matter of training. Pigs may be 

 trained to eat feeds of various kinds, as well as to eat dif- 

 ferent proportions of concentrates or of roughages. Since 

 the total quantity of feed eaten and the manner in which 

 it is eaten are such very important factors, it is highly 

 desirable that changes in a ration be made in such a man- 

 ner that the pig will at all times eat the required amount 

 with a decided relish. That is, changes should be made 

 very gradually, and the more gradual the better. 



GIVING THE PIG ITS FEED. 



It used to be said that the man who could do nothing 

 else could still be a farmer. Also that the farmer who did 

 not know much about any other branch of farming could
