was materially the same during the entire experiment. It 

 consisted of one part of nitrogenous food constituents to 

 from 3.27 to 3.76 parts of non-nitrogenous constituents. 

 From four and one-half to five ounces of corn meal were 

 added to every quart of skim-milk needed, to meet the 

 wants of the animal. This composition of the feed was re- 

 tained until the quantity called for per head had reached 

 eight quarts of skim-milk arul forty ounces of corn meal per 

 day. At this stage of the experiment the mixture of equal 

 weights of wheat bran and gluten meal was added to the 

 daily fodder ration ; beginning with sixteen ounces per head, 

 and closing up with twenty-five ounces. The exact amount 

 required per day was governed by the appetite of the ani- 

 mal ; the mixture served to meet the increasing demand of 

 the various animals on trial. It is a good rule to increase 

 the daily fodder rations only when called for, and always 

 gradually. 



The subsequent detailed record of our results shows that 

 the cost of feed consumed per pound of dressed weight pro- 

 duced varied from 6.2 cents to Q.6 cents, while from 4.10 

 to 4.18 pounds of dry matter contained in the feed con- 

 sumed had yielded one pound of dressed pork. The live 

 weights gained during the experiment amounted to 246.5 

 and 206.5 pounds.
