45 2 PRINCIPLES OF AGRICULTURAL CHEMISTRY 



Excessive quantities of fat in the feed may injure the quality of 

 the bacon. At the beginning of the fattening period, hogs may 

 consume as much as 30 pounds food per 1,000 pounds weight, but 

 as the fattening progresses, which ends in 3^ to 4 months, the 

 consumption of food sinks considerably, until towards the end, 19 

 to 20 pounds are used. The ration for the different periods of 

 fattening are shown in the table previously given. 



If the hogs are in poor condition, a preliminary period of 2 to 

 4 weeks with 4 pounds proteids is advisable. The proteids should 

 also be increased if the animals are not fully grown.
