carbohydrate to the required amount. If this does not 

 come out right the first time, it can easily be adjusted by 

 means of the preceding table. When this is done, add 

 sufficient water to bring up this part of the ration to the 

 standard : 



Pro- Carbo- 



Water. teln. taydiate. 



Alfalfa 3 lb. = .024 .021 .111 



Corn 10.0 lb. = 1.300 .700 6.600 



Corn 2.0 lb. = .260 .140 1.320 



Barley 6.0 lb. = .660 .480 3.900

The above mentioned quantities of feed, then, namely :

should be fed to these pigs for one day when they are two 

 months old. In order to get the increase specified by the 

 curves in the preceding cuts, under "Requirement of 

 Nutrients," an estimate must be made as to what the pigs 

 will weigh at the close of the week. Suppose that it is 

 estimated that the lot will gain 65 pounds this week, mak- 

 ing its total weight at the close of the week 750 pounds. 

 This estimated live weight then should be multiplied by 

 the increased quantities that are necessary at the end of 

 the week as follows: 



Water. Protein. Carbohydrate. 



11.7 .615 2.22 



Multiplying these by the estimated live weight the fol- 

 lowing is obtained as the requirement of nutrients at the
