CHAPTER XVII. 



Swine Rearing with Dairying 



Where dairies or butter factories are, or where the 

 milch cow is a factor for other purposes than the sale of 

 milk as such, the pig is a most useful and profitable ad- 

 junct. Upon the skim milk, judiciously used with other 

 and more substantial foods, he thrives, grows and fat- 

 tens, utilizing a by-product of tremendous volume which 

 without the pig would represent little of available value. 

 It is said that the skim milk from the butter factories of 

 Xew York alone amounts to nearly a billion pounds in a 

 single year. The use of this skim milk does much to 

 give relief from monotony so common in the hog's feed- 

 ing, besides adding to the returns from the other or main 

 foods with wiiich it is given, and every hog raiser is glad 

 to have it. 



VATAE OF SKIM MILK AND BUTTERMILK 



The editor of Hoard's Dairyman has formulated a 

 simple rule for estimating the value of skim milk. He 

 says : "To get at the value of skim milk in pig feeding, 

 if used alone, multiply five pounds of gain by the price 

 of live weight pork in the local market; or if fed in 

 conjunction with corn or barley meal, credit one pound 

 of the increased gain to the skim milk. If pork is worth 

 five cents a pound on foot, we have 25 cents a 100 pounds
