24 AGRICULTURAL EXPERIMENT STATION. [Jan. 



than 20 per cent, more dry organic matter than the cream- 

 ery buttermilk. This circumstance seemed to indicate a 

 waste of skim milk, as compared with the results obtained 

 in case of the former. As the skim milk was the most 

 costly article of the feed, a waste of that article cannot other- 

 wise but seriously affect the cost of the dressed pork obtained 

 by its use. 



In our first experiment — 1884 — the corn meal was charged 

 $28 per ton at the mill; creamery buttermilk, $1.37 cents 

 per gallon, the contractor's price ; and farm skim milk, two 

 cents asked for at the farm. Cost of feed per pound of 

 dressed pork at these rates amounted, in case of the creamery 

 milk feed, to 4.6 cents ; and in case of the farm skim milk 

 feed, to 5.8 cents per pound. 



As a charge of two cents per gallon for skim milk may 

 be considered somewhat arbitrary, its commercial value 

 for feeding purposes has been based, with more propriety, in 

 our subsequent experiments, on the amount of solid matter it 

 contains as compared with that of the creamery buttermilk, 

 taking the contractor's price of the latter as the standard. 



A recalculation of the cost of feed consumed in our first 

 experiment (1884) at the rate adopted in our second experi- 

 ment (1885), described within these pages, does not alter 

 the financial results of that experiment, so far as the relative 

 cost of each kind of feed is concerned.
