COWS it is best to soak it in two or tliree times its weiglit of 

 water, thereby providing a valuable succulent feed. It is often 

 sweetened with molasses and sold under various trade names. 

 Salvage grain is grain which has been damaged in ware- 

 house fires by fire, smoke, or water. It may consist of practi- 

 cally any grain, or it may be made up of a mixture of various 

 grains. It sometimes contains considerable weed seed. In 

 general, salvage grain has a fairly high feeding value for all 

 classes of farm animals, though it depends largely upon the 

 grains entering into its composition, and upon the extent of 

 the damage by fire and water. Occasionally such feeds are 

 made available to the farmer by local elevator fires at a very 

 low price and, in such cases, he should make use of them. It 

 usually will not pay him to buy salvage on the market, as 

 the price is often as much as the price of the undamaged grain. 

 Skim milk is relatively high in protein and mineral matter. 

 It is preeminently a feed for hogs. For young pigs it is 

 probably the best supplementary feed. It is also good as a 

 supplement to corn for fattening hogs. However, too much 

 skim milk should not be fed. WeanHng pigs should Ijc 

 started out on not more than 3 pounds of skim milk per pound 

 of dry concentrates fed. Later the milk should be reduced 

 to 2 pounds per pound of dry concentrates. When properly 

 combined with concentrates, 5 to 6 pounds of skim milk 

 are equal in feeding value to 1 pound of corn. Sweet milk 

 is no better than sour milk, except that the former is prefer- 

 able in the case of young pigs. Skim milk may be used also 

 for calves if carefully fed and properly supplemented. 



Buttermilk has about the same composition and the same 

 feeding value for pigs as skim milk. If allowed to ferment 

 in dirty tanks it may be dangerous.
