Meal Equivalents of Skim-Milk.

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,
