feed the grain dry, the milk may be fed separately. In either ease 

 clean, pure water should be provided for drinking. (Wyo. B. 74.) 

 To produce one pound of gain in live weight more total solids were 

 required with the milk rich in butter fat than with the milk poor 

 in butter fat. Later in the trials with pigs fed rich milk ad libitum, 

 serious digestive disturbances were noticed. (Conn. Storrs B. 31.) 



A ration of skim milk and grain, fed in the proportion of one 

 pound of grain to five pounds of skim milk, for young animals ; and 

 one pound grain to three pounds of skim milk, for older animals; 

 proved a better ration than a larger proportion of milk. The hogs 

 so fed gained faster, took less food for each pound of gain, and re- 

 turned more for each 100 pounds of skim milk. 



Adding skim milk to a grain ration enabled the hogs to gain 

 more than twice as rapidly as when fed grain alone, and each 100 

 pounds of skim milk effected a saving of 13 to 17.2 pounds of grain 

 according to the way in which the milk was fed. As, on the average, 

 100 pounds of skim milk contains slightly less than 10 pounds dry 

 matter, it is evident that a pound of dry matter in skim milk is 

 worth as much as 1.5 pounds of grain. 



When the price of grain is high, slower, but more economical 

 gains are made by feeding a small quantity of grain and giving all 

 the milk the hogs will eat. When so fed, considerably better results 

 are obtained by feeding on pasture than in pens. 



Hogs will gain fairly well on a ration of skim milk alone, but 

 we have found it difficult to keep them in good health when so fed 

 in pens. When this ration is fed on pasture, the hogs keep in better 

 health, gain a little more rapidly and make more economical gains. 

 Such a ration is not to be recommended when grain can be obtained 

 at a reasonable price. (Utah B. 94.) 



Too often the value of the so-called by-products of the farm is 

 not fully realized by the farmer. The dairyman, for instance, whose 

 first object is to produce as much milk as possible that he may sell 

 the butter fat, may overlook the value still remaining in the skim 

 milk and buttermilk after the fat has been taken from them. As a 

 matter of fact from 10 to 20 per cent of the value of milk lies in the 

 skim milk when it is properly fed to growing young animals. 

 (Ariz. B. 47.) 



Skim milk has proven to be the most efficient supplement to 

 shelled corn or corn meal, used in the experimental feed lots at the 

 Station for the past five years in fattening hogs. (Ind. B. 137.) 



As a result of five years' work it is found that most economic re- 

 turns are secured with skimmed milk when corn meal is the grain 

 used. The proportion of corn meal to skimmed milk may be varied 

 without apparently affecting results. In no case should the amount 

 of skimmed milk fed be greater than the pigs can quickly and 

 easily consume. (N. Y. Cornell B. 199.) 



Hoge fed in the ratio of 1 pound of grain to 3, 6, 9 and 12 

 pounds of skim milk made the largest gains on from 9 to 12 pounds 

 of skim milk. The consumption of skim milk reduced the consump- 

 tion of concentrates considerably, though the cost of a pound of gain
