the country and everywhere give very satisfactory 

 results not only in the cost of production, but 

 in the gains of pigs. The same story of the great 

 value of skim milk comes from the southern 

 states, Arizona, and other parts of the southwest, 

 Oregon and Washington, the central dairy states 

 and Canada. On the basis of Canadian ex- 

 perience, it is recommended that skim milk be 

 fed in rations of five pounds for each pig daily. 

 In Canada skim milk lias been found to possess 

 a feeding value about one-fifth as great as that 

 of corn. 



Molasses. While cheap molasses and various 

 other sugar cane and sugar beet products are com- 

 ing into great value in feeding horses, mules and 

 steers these materials do not give much promise 

 as profitable pig feeds. To be sure they have 

 not been thoroughly tested with pigs, but in one 

 experiment where a pen of five pigs received 

 eight pounds of corn meal, twelve pounds of molas- 

 ses and twenty pounds of skim milk daily the pigs 

 soon got off feed and some of them died. The 

 molasses seemed actually to exercise a poisonous 

 effect upon them and it became necessary to leave 

 out this part of the ration. Since there are so 

 many other excellent feeds known to produce 

 pork under economic conditions, it appears at 

 present, at least, to be unnecessary to attempt 

 to use molasses as a pig feed. 



Tankage and Other Animal Materials. Of all 

 domestic mammals pigs make the best use of 

 animal feeds. Every one who has been near 

 country slaughter-houses knows that a consid- 

 erable number of pigs are constantly kept about 

 such places and fed on the offal of slaughtered 

 animals. They make very satisfactory gains on
