On such a combination of feeds, growing pigs make large and economical gains. 

 Even on alfalfa pasture, it is advisable to feed tankage or some other supplement

Whey. — Pig-feeding trials at American stations and in Denmark 

 show that 1,000 lbs. of whey, such as is obtained from American 

 cheddar cheese factories, will save 100 lbs. of grain when properly 

 combined with concentrates. Unlike skim milk and buttermilk, whey 

 contains only a fair amount of protein, having a nutritive ratio of 

 1 : 6.8. It should therefore not be fed with only corn or other cereals, 

 but along with some protein-rich concentrate like tankage, wheat 

 middlings, or linseed meal to balance the ration. Slightly sour whey 

 has as high value as sweet whey, but that which is allowed to putrefy 

 in filthy tanks is a dangerous feed.
