FEEDING AND FATTENING 335 



These hogs are called pen holders, and have no influence 

 on the market. 



Dead hogs are those killed in the cars in transit, and 

 <'',re used for the manufacture of grease, soap, and ferti- 

 lizer. "If they weigh loo pounds or over they sell for 

 75 cents per loo pounds. If they weigh less they fur- 

 nish no revenue to the producer or shipper, the cost ot* 

 handling the same being held equal to their value." 



About two-fifths of the world's hog supply is produced 

 in the United States, and about six-sevenths of these 

 are produced in the Alississippi valley ; hence this section 

 of the country has developed the fat or lard liog- and 

 has set the standard for hogs in other parts of the 

 United States. 



The fat or lard hog is such because corn has been his 

 ])i-incipal feed and because there has been a demand 

 for pork from such a hog, and lie will conform to the 

 present prevailing type just as long as corn remains his 

 |)rincipal feed. 



Butcher hogs are the best hogs from the fat or lard 

 hog standpoint that come to market, and should be used 

 as a standard for comparison. 



From the bacon market standpoint the English bacon 

 hog is the ideal toward which hogs are being developed. 



To the close observer it is apparent that the gradually 

 changing conditions brought about by the development 

 of the United States, and the increase in the price of 

 corn resulting from its varied commercial uses, cause the 

 liog to be fed a more mixed and usually a more nitroge- 

 nous ration. It is not improbable that this will in the 

 future affect the type of the hog of the Ignited States,
