242 Pork Production 



in the time required to produce 100 pounds of gain. The 

 average weight at the close of the experiments was 229 

 pounds for those fed skim-milk or buttermilk, and 184 

 pounds for those fed corn alone. To have made the 

 latter as heavy when sold as those fed the milk rations, 

 it would have been necessary to have continued them 

 on feed 43 days after the experiments closed. 



Not only were the gains faster for those fed milk, but 

 they were also cheaper. The feeding of 799.4 pounds of 

 buttermilk or skim-milk resulted in a saving of 190.81 

 pounds of corn; or in other words, 4.18 pounds of milk 

 had the equivalent value of 1 pound of corn. On the basis, 

 then, of the average result of these seven experiments, the 

 value of skim-milk or buttermilk in reducing the cost of 

 gains when corn alone is fed would be as shown in the 

 following table :

 MILK WHEN FED WITH CORN TO FATTENING PIGS 



According to these valuations, therefore, the price of 

 a bushel of corn divided by 2.34 will give the value of 100 

 pounds of skim-milk or buttermilk when fed under these 

 conditions. 



These values, it should be understood, are based entirely 

 on the saving of corn required to produce a given gain. 

 They do not include the important additional advantage 

 of more rapid gains and the earlier market finish which also 

 resulted from their use. On the other hand, these figures 

 do not mean that the feeder can necessarily afford to pay
