Roots.—In Henry’s “Feeds and F eeding”’ there is an 
excellent summary of Danish experiments with roots for swine. 
The meal equivalent of roots was found to vary in a marked 
degree in different trials, and 100 pounds of barley were found 
to be equivalent to 600 to 800 pounds of mangels and 400 to 
S00 pounds of stock beets. In the United States and Canada, 
wide variations in the meal equivalent of roots have also 
oceurred in various tests. The following table gives an idea of 
the range of values found at several stations: 
Meal Equivalent of Roots. 
Central Experiment Farm ...... 100 pounds meal=786 pounds roots 
Ohio Experiment Station ....... 100 pounds meal = 642.5 pounds roots 
Montana Experiment Station .... 100 pounds meal==529 pounds roots 
Utah Experiment Station ....... 100 pounds meal = 455 pounds roots 
Ontario Agricultural College .... 100 pounds meal = 441.5 pounds roots 
AVOTABO 8s noid ae won yaadwent 100 pounds meal = 570.8 pounds roots 
The variations in these trials is similar to the variations 
in the Danish experiments. Ontario obtained a remarkably 
high mea] equivalent for roots, and it is worthy of note that 
in the Ontario trials the roots were pulped and mixed with an 
equal weight of meal, the hogs being fed all thev would eat of 
the mixture. 
In the writer’s experience hogs fed roots are thriftier look- 
ing and possess better appetites than hogs fed meal alone, and 
it is no doubt due to their influence upon the general health 
of the animal that roots are able to make such a favorable 
showing. The degree to which the general thrift of the animals
