"In the above table the large number of trials reported for pigs
weighing up to 350 lbs. each furnishes reliable data. After this point
is reached the number of animals is too small to give reliable averages.
The heavy weight hogs reported in the last three lines of the table were
fed by the writer (Professor Henry). They were mature specimens, with
large frames and in lean flesh when feeding began, having been summered
on pasture without grain. The figures are introduced to show what may be
accomplished with mature hogs when they are in thin flesh at the
beginning of fattening.

"We learn from the main portion of the table that from 105 to 435 pigs
were employed in calculating each line of data. The number of trials
furnishing the data varied from 19 to 119, and were conducted by from 3
to 13 experiment stations.

"Amount of food consumed daily by the pig. The sixth column of the table
shows the average amount of feed consumed daily by pigs of different
weights. From it we learn that pigs weighing less than 50 lbs. each,
averaging 38 lbs., consumed on the average 2.23 lbs. of grain or grain
equivalent, daily. As the animal increased in weight there was a gradual
increase in the amount of food consumed, until we find the 450 lbs. hog
eating 10 lbs. of grain daily, or more than four times as much as the 50
lbs. pig.

"Feed per 100 lbs. live weight: In the seventh column it is shown that
pigs weighing 38 lbs. consumed 5.95 lbs. of feed for each 100 lbs. of
live weight. This is about 6 per cent of their live weight. As the pigs
grew larger they consumed less feed for 100 lbs. of live weight, until
with the heaviest hogs the feed consumed was little more than 2 per cent
of their live weight. Here was a decrease of about two-thirds in the
feed consumption per 100 lbs. between early weight and maturity.

"Average daily gain: In the next column are presented data concerning
the daily gain of the pig. It is shown that the 38 lb. pig gained .76 of
a lb., or 2 per cent of its own weight daily. As it increased in size
the pig made larger daily gains, the maximum being reached with those
weighing 271 lbs., which made a daily gain of 1.46 lb. With large thin
hogs the gain reached 1.98 lb., or practically 2 lbs. per day, but these
animals, because of their mature frames and thin flesh, were fed under
exceptional circumstances.
