DAIRY BY-PRODUCTS. 

 COMPOSITION OF BY-PRODUCTS. 



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

 dairymen 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 eight 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 average 

 from fifteen to twenty pounds. Taking the latter figure
