grain about one-half pound per head daily. However, good forage un- 

 der average conditions is about equal to a maintenance ration. The 

 greatest economy through the use of forage is obtained where the hogs 

 are fed from one-lialf to tM'^o-thirds of a full ration. A full ration for 

 a hog under ordinary conditions is about three to three and a half 

 pounds of grain per hundred pounds live weight per day. One-half to 

 two-thirds of a full ration would, then, be from two to two and one-half 

 pounds of grain per hundred pounds live weight per day. If a full feed 

 is given the hog while on pasture he will have no desire for other food 

 and will therefore make no use of the forage which is before him. On 

 the other hand, if he is given too little grain he may have to hustle too 

 much and will not make gains rapidly enough for profitable growth. 

 The following tables will illustrate the economy in supplying less than 

 a full feed while on forage :

Lot 1 did not do well enough to warrant repetition of the test. 

 While a very good price was obtained per bushel of corn fed, yet the 

 pigs had an unthrifty appearance — they had the appearance of being 

 stunted. 



Lot 2 were thrifty, but not fat.
