1 6 BULLETIN 74. 
The pigs in Pen III. on corn, and those in Pen IV. on 
wheat and barley, practically consumed increasing amounts 
of food up to the end of the experiment and the respective 
lots practically consumed the same amounts of grain each 
week for the last nine full weeks. The last four weeks the 
amount of sugar beets given to those in Pen V. was re¬ 
duced, but the grain was increased as they would consume 
it. 
Table II. page 17 gives the individual weights each 
week for all the pigs. The last column gives the total gain 
of each pig during the experiment and the first column the 
ear-tag number. Food given each lot |is given in 
Table I. The last weight of each pig, taken May 30th or 
]une 6th, was made after they had been off feed for 24 
hours before slaughter, and represents the gain during the 
last week, less the shrinkage. Pig No. 80, in Pen II, was found 
to be in pig soon after the feeding began and was left with 
the lot to see what the final effect would be. She dropped 
a litter of three pigs March 29th and killed all of them. 
She was left on feed and made a larger total gain than any 
other pig in that pen. 
Table III. gives the total weekly gains made by the four 
pigs in each pen and the last column gives the total gain of 
each lot for the whole period, less the 24 hours shrinkage 
before slaughter. The minus sign before a number indi¬ 
cates a loss of weight. There is much variation in the gains 
made week by week, the differences being especially notice¬ 
able in Pen I., fed on sugar beets, and in Pen II., given pulp 
and grain. The gains did not vary so much with the grain 
rations.
