where roots were added. in both experiments tin- grain ration was 1 
pari coin meal, 2 parts shorts, fed as slop. No drink other than water 
was given. In the firsl experimenl mangels were fed; Ln the second 
the roots were sugar beets sliced and fed in the slop, and they were 
relished more than the mangels. 
At the Ontario Agricultural College, Day" fed four lots of pigs in 
pens as follows: 
Lots I and II were made up of 4 grade Yorkshire pigs each from the 
same litter, about seven weeks old; Lots III and IV contained 5 grade 
Yorkshire pigs each from the same litter, about 9 weeks old. Lot I 
received barley and middlings; Lot II received barley and middlings 
with an equal weight of raw pulped mangels; Lot III received coin 
and middlings; Lot IV received corn and middlings with an equal 
weight of raw pulped mangels. The proportion of grain to middlings 
was 1 : 2 in all lots at the beginning of the experiment, and was grad- 
ually changed as the pigs increased in weight and age until it was 2 : 1 
toward the close. 
At the Utah Station, Foster and Merrill 6 conducted two experiments 
to compare a ration of bran and sugar beets with rations of corn meal, 
ground wheat, and corn meal and peas. In the first experiment Lot 
I received corn meal, Lot II received ground wheat, and Lot III 
received sugar beets with a one-third ration of bran. In the second 
experiment Lot I received a mixture of equal parts of corn meal and 
ground peas, Lots II and III being fed as in the first test. The pigs 
were fed in covered pens, and were given all the}' would eat. There 
were 3 in each lot. 
At the Montana Station, Shaw c fed one lot of hogs on grain only 
and another on the same grain ration with sugar beets added. The 
following table shows the results of these experiments:
