The Ontario Agricultural College reports a trial in which 
355.6 pounds of skim-milk proved equal to 100 pounds of meal. 
The proportion of milk to meal was about 2.5 to 1, and the 
result is similar to the Wisconsin result with a similar propor- 
tion of milk to meal. 
The Minnesota Experiment Station reports six trials in 
which the proportion of milk to meal varied, the highest pro- 
portion being about 5 pounds of milk to one of meal. The 
average of these trials gives 467 pounds of milk equivalent to 
100 pounds of meal, which is very close to the Wisconsin 
average, 
Utah experiments show 431 pounds of skim-milk equal to 
100 pounds of grain, and Tennessee experiments 476 pounds of 
skim-milk equal to 100 pounds of grain. The Tennessee results 
are practically identical with the Wisconsin average, and the 
Utah results are reasonably close. 
These experiments show that, where skim-milk can be ob- 
tained conveniently and in suitable quantity, it has a very 
considerable value in hog feeding. When meal is worth $20.00 
per ton, skim-milk is easily worth 20 cents per hundred pounds, 
unless an exceptional amount of labor is involved in procuring 
it. For young pigs just after weaning, however, its value is 
very much higher than for older hogs. 
Sweet vs. Sour Skim-Milk.—Several experiments with 
sweet and sour skim-milk indicate that there is little or no 
difference in the feeding value of the two products,—in fact,
