FEED COST OF RAISING THE PIG TO MARKET WEIGHT 

 OR BREEDING AGE 



In the following tables the feed cost of growing and 

 finishing the market pig and of developing the gilt to

 assume in the case of the pigs fed on forage during the 

 summer that they were grazed at the average rate of 

 fifteen to the acre.
