SKIM-MILK.

more profitable to have sold them when averaging 175 Ibs. 

 each than when averaging 240 Ibs. 



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

 the assumption that the skim-milk used was worth 25 cents 

 per 100 Ibs. 



We will now see what its value actually was under the 

 conditions of this experiment, the price of live hogs being 4 

 cents per pound and the cost of grain as previously men- 

 tioned. 



For our present purpose we will neglect the first cost of 

 the pigs and note the value of the gain of live weight for each 

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

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 remainder represents the value of the skim-milk, which, 

 divided by the amount, gives the value per 100 Ibs. The 

 showing is certainly a favorable one, and with thrifty pigs 

 from 20 to 30 cents per 100 Ibs. ought to be and can be real- 

 ized for skim-milk when live hogs sell at 4 cents per pound. 

 It must be constantly kept in mind, however, that they must 

 be sold by the time they reach a live weight of from 200 to 

 230 Ibs.
