10(3 AGRICULTURAL EXPERIMENT STATION. [Jan. 



fodder rations. Our allowance of a loss of thirty per cent, 

 of the essential fertilizing constituents contained in the food 

 consumed, in consequence of the development and growth 

 of the animal, is purposely a liberal one. The adoption of 

 this basis for our estimate tends to strengthen our conclusion 

 that the raisino; of pi2:s for the home market can be made a 

 profitable branch of farm industry, even with comparatively 

 limited resources of skim-milk. 



The daily supply of skim-milk has not exceeded, at any 

 period, eight quarts of milk during our later experiments, 

 from the third to the ninth inclusive ; most of the time it 

 has been from four to five quarts per head. The relative 

 proportion of corn meal, wheat bran and gluten meal has 

 been frequently altered in case of different experiments, as 

 well as at difierent stages of the same experiment, with 

 varying results. The ninth experiment, which has been 

 described in detail in our sixth annual report, has been, 

 from an economical stand-point, thus far the most successful 

 one. A brief abstract of that experiment may here suffice 

 to show our late mode of compounding fodder rations for 

 pigs at different stages of growth, in connection with the 

 financial results we secured. 



The summary includes our entire series of pig feeding 

 described in previous reports, and also the last one, the 

 tenth, which is for the first time published in detail in some 

 succeeding pages.
