than the lard hog, and possibly this may explain why corn 
is unsatisfactory for feeding bacon hogs. It is possible also 
that the difference in the methods of curing may have an 
influence. 
7. Beans seem to have a more marked effect than corn in 
producing softness, and should not be used for finishing bacon 
hogs. 
FEED REQUIREMENTS OF GROWING AND FATTENING SWINE. 
Professor Wm. Dietrich, of the Illinois Experiment Station, 
has done much careful work upon feeding standards for swine.* 
Below are given some of the leading features of the standard 
evolved by him, though it is admitted that certain modifications 
may be necessary as the result of further investigation. 
The standard starts with pigs two months old and carries 
them along until they are eight months old, at which time they 
are ready for market. 
Water.—As a rule, pigs are allowed to take as much water 
as their appetite dictates, but Professor Dietrich believes that 
in warm weather pigs ordinarily drink too much water and in 
cold weather they do not drink enough, so that he prescribed 
definite quantities of water for each week of the pig’s life from 
two months to eight months of age. The standard calls for 
12 pounds of water daily per 100 pounds, live weight, for pigs 
two months old, and during the next 26 weeks, or until the 
pig is eight months old, there is a gradual and uniform decrease 
in the amount of water to 4 pounds per day for 100 pounds, 
live weight, for pigs eight months old. The reduction in water 
given daily per 100 pounds, live weight, is about .3 of a 
pound for each week. 
Crude Protein.—For pigs two months old the standard
