RETURNS FROM ANIMALS 



two steers. In many well-known ways, pigs 

 consume products which would otherwise 

 be wasted. This is especially true in the 

 more densely settled sections of the world. 



On account of their prolificacy, the 

 returns obtained for the amount of capital 

 invested is greater than in the case 

 of sheep, cattle or horses. Ten sows, 

 worth $100 to $150, are sufficient to 

 produce 100 pigs; 75 to 80 ewes, worth 

 from $300 to $500, are required to produce 

 an equal number of lambs; 1 10 cows, worth 

 $4,500 to $6,000, to produce 100 calves ; and 

 200 mares, worth from $20,000 to $30,000, 

 to guarantee 100 foals. To put the matter 

 in another way, the capital invested in 

 swine may be reproduced in the offspring 

 ten times in one year; the capital invested 

 in horses not more than once in five years. 



In general, 500 pounds of maize will pro- 

 duce 100 pounds of pork, which is equiva- 

 lent to eleven pounds of pork from a bushel. 

 Since hogs are so largely produced from 

 maize, the price of maize and the price of 

 pork are very closely related. For example,
