words, stating thai fche value for sugar beets for pigs is "derived 
imt so much from the nutrients in the dry matter which they contain 
as from the influence they exerl on digestion and assimilation." 
'This action of roots in the ration is undoubtedly similar to what lias 
already been noted in the case of dairy by-products and pasture. 
The improvement that roots bring about in the condition of the diges- 
tive system must also affect indirectly the entire system and thus 
promote the general health. 
Henry found the results at three American stations to be that about 
G15 pounds of roots saved UK) pounds of grain. The Danish experi- 
ments give 600 to 800 pounds of mangels and from 400 to 800 pounds 
of fodder beets as the feeding equivalent of 100 pounds of grain." 
The average of the results here given indicates that about 515 
pounds of roots saved 100 pounds of meal, a somewhat higher value 
for roots than that given in previously published work. 
An experiment conducted by Shaw 6 at the Montana Station, the 
results of which were published since the foregoing figures were com- 
piled, showed an average daily gain for pigs of 1.58 pounds, at a cost 
of $4.60 per 100 pounds gain on grain only (9.11 pounds of grain per 
head daily); a second lot, on grain and sugar beets (6.65 pounds grain 
and 4.58 pounds sugar beets per head daily) made an average daily 
gain of 1.64 pounds, at a cost of 83.80 per 100 pounds. There were 4 
pigs in each lot and they were fed 50 days. As a sidelight on the pos- 
sibilities of pork production in the irrigated Northwest, it is interest- 
ing to note that Shaw found his net profit from feeding these 8 pigs 
to be $14.12, "or '53 per cent on the investment in fifty days." 
Cow/paring various roots. — At the Central Experimental Farm in 
Canada, Grisdale c fed four lots of pigs to compare the feeding value 
of turnips, mangels, and sugar beets. In each case the meal mixture 
fed consisted of one-half corn, the other half being equal parts of 
oats, pease, and barley. In addition each pig was given 3 pounds of 
milk daily and all the roots he would consume. The roots were fed 
as follows: Lot I, turnips fed pulped; Lot II, mangels fed pulped; Lot 
III, sugar beets grown for forage, fed pulped; Lot IV, sugar beets 
grown for sugar production, fed pulped. The results were as follows:
