Pork Production 



The larger the proportion of skim-milk given, also, the 

 more rapid were the gains, but the value of the skim-milk 

 in reducing the amount of corn required to produce 100 

 pounds of gain was greatest when the smaller proportions 

 were fed (see Table XC, page 243). With an abun- 

 dant and cheap supply of skim-milk available, it would 

 be profitable to feed the larger proportions. 



Skim-milk or buttermilk versus tankage. 



Summarizing the results from all the experiments in 

 which skim-milk or buttermilk were compared with 

 tankage for fattening pigs, the average results are stated 

 in Table XCV. 



Table XCV. — Summary : Skim-Milk ok Buttermilk ver- 

 sus Tankage as a Supplement to Corn for Fattening 

 Pigs (Av. 8 Exps.) 



According to these averages, 753.25 pounds of skim- 

 milk or buttermilk replaced or were equivalent to 91.18 

 pounds of corn and 35.74 pounds of tankage. As based 

 on the amount of feed required to produce 100 pounds of 

 gain, then, skim-milk and tankage would have the relative 

 valuies shown in Table XCVI.
