Feeds and Feeding. 



Results with fattening animals per 100 pounds live weight, per week 



Warington. 



Results obtained in relation to food consumed. 



* In calculating the amount of food consumed for the production of 

 heat and work, it has been assumed that the fat in the increase has been 

 derived entirely from the fat and carbohydrates supplied by the food. 



t The manure is exclusive of litter. 



Warington tells us in the first table that pigs are able to con- 

 sume far more food in proportion to their live weight than 

 either sheep or oxen. This is due to the concentrated and digesti- 

 ble character of the food commonly supplied the fattening pig, 

 and to the great capacity of this animal for assimilation. The 

 proportion of stomach is greater in the ox or sheep than in the 

 pig, being for 100 pounds live weight, 3.2 for the ox, 2.5 for the 

 sheep, and .7 for the pig. On the other hand, the proportion of 

 the intestines is greater with the pig. (32) Ruminants are thus 

 best fitted for dealing with feeds requiring prolonged digestion, 

 while the pig excels in the capacity for assimilation.
