CREAMERY BY-PRODUCTS. 

 SKIM-MILK AND ITS PRODUCTS. 



Skim=milk as a Feed. This is a question in which 

 creamerymen should take greater interest because, as a 

 rule, the feeding value of skim-milk is underestimated. 

 Feeding trials show that five pounds of skim-milk are 

 equal to about one pound of grain (corn, barley, oats). 

 They also show that on an average four pounds of grain 

 will produce one pound of gain with young pigs, while 

 five pounds will produce the same gain with pigs from 

 six to twelve months old. On this basis twenty pounds 

 of skim-milk are required to produce one pound of gain 

 with young pigs and twenty-five pounds with older pigs. 

 With pork at 8 cents a pound, one hundred pounds of 

 skim-milk will produce 40 cents worth of pork with young 

 pigs and 32 cents worth with older ones. 



The amount of skim-milk required to produce a pound 

 of veal is shown by feeding trials to range on an aver- 

 age from fifteen to twenty pounds. Taking the latter 

 figure and valuing veal at 7 cents a pound, skim-milk is 

 worth 35 cents per 100 pounds for veal production. 



The highest returns from the feeding of skim-milk 

 are secured when fed to poultry. Careful experimental 

 tests show that as high as 75 cents per 100 pounds may 

 be realized for skim-milk when fed to poultry.
