Feed Requirements of Swine.— Next to the dairy cow, the 

 hog is the most economical producer of human food materials among 

 our farm animals, and it stands close to the cow in this respect. 

 Jordan has shown that 100 pounds digestible organic nutrients 

 in the ration produce the following amount of edible solids in 

 the form of the various animal products : 



Milk 18 pounds 



Pork 15.6 pounds 



Veal 8.1 pounds 



Poultry or eggs 3.5 pounds to 5.1 pounds. 



Beef 2.75 pounds 



Mutton 2.60 pounds 1 



While these are only average figures, and may not hold true in 

 individual cases, they show that the hog has a wo nderful capacity
