The figures shown in Table XVIII involved 450 hogs and 83.2 
acres of corn. Only four of the fields contained more than 1 acre 
each, so that 10 of the lots were small. The average initial weight 
of the hogs in the 14 lots ranged from 68 to 124 pounds, only three 
lots having average initial weights as high as 100 pounds per pig. 
The length of the hogging period ranged from 21 to 97 days. With 
10 of the 14 lots this period ranged from 44 to 77 days. The gains 
per acre ranged from 335 to 1,377 pounds, depending chiefly on the 
yield of corn and the character of the hogs used. The average daily 
gain in all but five cases exceeded 1.5 pounds per pig. On the basis 
of the estimated yields in the seven cases in which estimates are avail- 
able, the corn consumed per 100 pounds of gain ranged from 354 
pounds (6.3 bushels) in lot 1 to 485 pounds (8.7 bushels) in lot 18. 
The average for these seven lots is 409 pounds. This is somewhat 
lower’ than the corresponding figure (450 pounds) indicated as an 
approximation for the lots hogging corn without supplements. 
There appears to be no doubt that supplements reduce the corn 
requirement. Just how great this reduction is can not be definitely 
determined from the figures given in Tables XVII and XVIII, but 
valuable indications with reference to alfalfa pasture and tankage as 
supplements may be found by comparing the results secured at the 
Scottsbluff Experiment Farm with the six duplicate lots of three 
hogs each which were used in the experiments in 1914 and 1915. This 
comparison is shown in Table XTX, in which the average results of 
the trials for two years are presented.
