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 



* Illinois Circulars 126 and 133 give details of the standards.
