appreciated by many who feed pigs. With the present price* 

 there is but one way in which pork can be produced at a profit, 

 and that is by producing a two hundred pound pig in the short- 

 est possible time. 



We see from Table II that the cost of growth and the amount 

 of food required to produce one hundred pounds of growth in- 

 crease as the pigs grow older, and it would have been much 

 more profitable to have sold them when averaging one hundred 

 and seventy-five pounds each than when averaging two hundred 

 and forty pounds. 



Thus far we have, for convenience, figured all results on 

 the assumption that the skim-milk used was worth twenty-five 

 cents per hundred pounds. 



We will now see what its value actually was under the con- 

 ditions of this experiment, the price of live hogs being four cents 

 per pound, and the cost of grain as previously mentioned. 



For ourfpresent purpose we will neglect the first cost of the 

 pigs and note the value of tliegatn of live weight for each period, 

 where skim-milk was used as a part of the ration. 



TABLE IV. 



This table is constructed by determining the value of the 

 gain for each skim-milk period and subtracting therefrom the 

 cost of the corn meal which was fed with the skim-milk, the re- 

 mainder j represents the value of the skim-milk, which, divided 

 by the^ amount gives the value per hundredfpounds. The show- 

 ing is certainly a favorable cne, and vith ihrifly pigs trcm twenty
