to Indian corn. The results obtained in feeding skim milk and 
corn to pigs depend, to a large extent, on the proportions in which 
the two feeds are given. Skim milk alone will produce very un- 
satisfactory results in feeding pigs,° and more than five or six 
pounds of skim milk per pound of corn is also likely to give poor 
returns. The ratio of skim milk to grain to be fed will depend 
upon the relative price of the two feeds and on the age of the 
animals; fed to pigs shortly after weaning, larger proportions of 
milk will give better results than with older animals. The results 
of a large number of trials at the Wisconsin station and else- 
where showed that a ration of 3 to 1 will give most economical 
results in gain of live weight. Fed in the ratio of 1 to 3 pounds 
milk for each pound of corn meal, Henry found ?° that 327 pounds - 
of milk were required to save 100 pounds of meal; in the ratio 
of 3-5: 1, 446 pounds; 5-7: 1, 574 pounds, and 7-9: 1, 552 pounds, 
and, on the average for all trials, 475 pounds (p. 207).

pasture were $22.84 per acre. (Missouri Station.) 
Corn is the best supplemental grain to feed with skim milk or 
_. buttermilk for growing pigs; with whey, on the other hand, wheat 
shorts, pea meal, or linseed meal as a part of the grain ration is to 
be preferred, being mixed with corn in increasing proportions of the 
latter as the animals approach maturity.** Trials made in this 
country and abroad have shown that 1000 pounds of ordinary whey,
