104 TWENTY-FIFTH ANNIVERSARY REPORT. 
increase in weight was not at a profitable rate even with the clover 
rated at less than $1 per ton. 
When the clover was fed with corn meal and constituted not more 
than about 40 per ct. of the total food there was a much more rapid 
rate of growth and the increase in weight was a profitable one even 
with the fresh clover rated at over $4 per ton. The ration with the 
small amount of salt added again gave slightly the better results. 
‘SORGHUM FORAGE.! 
When pigs that had been fed clover were changed to sorghum 
there was at once an increased consumption of food. The sorghum 
was fed as cut in the field, the entire stalk and seed. This was fed 
to the extent of nearly go per ct. of the total food. The increase in 
weight was much faster than when clover was fed, but under one 
ration was not at a profitable rate. Under the contrasted ration to 
which a small amount of salt was added the gain in weight was made 
at a profit with the fresh sorghum rated at $2 per ton. 
Feeding trials during another season showed a profitable rate of 
growth under rations in which sorghum constituted during some 
periods over 65 per ct. of the total food. But the increase in weight 
was much faster and at a lower cost for food when the sorghum 
constituted from ro to 12 per ct. of the total food than under the 
contrasted rations in which it constituted from 56 to 67 per ct. With 
the sorghum forage placed at a lower valuation the difference in 
cost was less. 
MANGELS FOR PIGS.” 
Of several coarse foods tried none was eaten entire or without 
considerable waste except mangels (or beets). 
In a preliminary trial for several weeks a pen of pigs fed mangels 
to the extent of about 90 per ct. of the total food, half the dry 
matter in the ration coming from them, made a profitable increase in 
weight. Less dry matter in the food was required per pound gain in 
weight than is usual under rations not including a large proportion 
of milk. Another lot fed the same ration with addition of a little 
salt gained only about half as much in weight and at little profit 
except with a low price for mangels. 
In further experiments with six lots of pigs, in several separated
