LIVESTOCK ON THE FAKM 



the carbohydrates when added will be nearly equal to the 

 required quantity. Next list the nitrogenous concentrate, 

 soy beans, in sufficient quantity to bring the protein as well 

 as the carbohydrate up to the required amount. If the result 

 does not come out right the first time, it can easily be adjusted 

 by the use of the table. When this is done add sufficient 

 water to make the required amount. 



The above-mentioned quantities of feed, then — namely; 

 alfalfa, 0.9 pound; corn, 13.3 pounds; barley, 6.7 pounds: 

 skim milk, 40.0 pounds; soy beans, 4.6 pounds; water, 49.6 

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

 two months old. 



In order to get the increase specified by the charts an esti- 

 mate 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 during the week, making its total weight at 

 the close of the week 750 pounds. This estimated live weight 

 should then be multiplied by the quantities given by the 

 charts for the age attained. The results will be as follows:
