Roots. — ^In Henry's " Feeds and Feeding " 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 pouxids of barley were found 

 to be equivalent to 600 to 800 pounds of mangels and 400 to 

 800 pounds of stock beets. In the United States and Canada, 

 wide variations in the meal equivalent of roots have also 

 occuiTed 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 



Average 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 meal 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 they 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
