From the table of Feeding Standards we find one pig two 

 to three months old requires daily : proteine, 0.38 pounds ; 

 and carbohydrates and fat, 1.5 pounds. Then ten pigs 

 would require of proteine, 3.8 pounds, and of carbohy- 

 drates, 15 pounds. 



By a few trials I lind that these amounts will be supplied 

 with sufficient exactness for practical purposes by the fol- 

 lowing quantities of the foods I propose to use, viz. : — 



Fifty pounds skim-milk, furnishing proteine 1.8 pounds, 

 and carbohydrates and fat 2.0 pounds; 11 pounds corn 

 meal, furnishing proteine 0.0 pounds, and carbohydrates 

 and fat 0.13 pounds ; 4 pounds gluten meal, furnishing pro- 

 teine 1.2 pounds, and carbohydrates and fat iJy'o pounds. 

 Totals, proteine 3.0 pounds, and carbohydrates 14.6 pounds. 



In this calculation the fat has been reduced to carbohydrates 

 by multiplying by 2.5, as already explained. In the above 

 ration the nutritive ratio is 3.0 : 14.6, which equals 1 : 3.8, 

 which is very nearly what our table calls for. 



It is not of course expected that an}" farmer will blindly 

 folloAV such a standard. It 1)ut serves as a guide in obtaining 

 foods containing nutrients in the proper proportions, and, to 

 a certain extent, as to quantity. The farmer may wisely 

 vary the amounts, but not the proportions, according to the 

 appetites of his animals. 



When with the increasing age of the pigs it becomes desir- 

 able, according to our table of feeding standards, t ) feed a
