''No law OF raiure says Professor J. ".
Sanborn, lis more certain than the lsv that
the older and isrser an animal grows the
more fooa il takes to make pound of
growth" Ills role applies to al classes CT
animals in lis opini T., for in experimenting
with the view q deteT1u iniug the relative IL
crease es con- psfed vi b tgs Il was found that
~ pounds 81 Lay FED to calves gave one
pound Of arovfh; bst when the calves be
came yeaIlirgs itIsqairsd as much hay
to give the increae Of 4 9, uud while two
year-old stock consumed three times as much
With only the same gain IN growth.
In eorrobosation Of the above, Sir ]. B.
Lawes, Of Euglapds ms always maintained
that the larger he pig the more food IS re-
quired 70 make round OF growth, and the
Columbia MOI Statesman, which hss also
advocated the advantage CT early maturity,
ST. tc5 thatthe Germsns have organized their
expeIience " table which demands that 3
PIC, when between two and three months
old, if weighing fifty poUnds, should DO sup
piled with pounds organic matter daily;
Dut the term Used, organic matter" applies
only to the solid, complete fC ID, and may
iuCiude any subslauce, variety Of suo-
siarCes, provided the suiiciency Of organic
matter s. CHAINED iheTefrom. With the
allowarcs q = : 0uifis OF organic matter fo-
hfiy s0IUds live weight, an increase to
double weigh, calls for more than three
times IS much, IS 81 pounds OF organic
mstfer is necessary for a pig weighing 100
pounds, snd the increase is still greater as
the live weight If TIE Dig bccsmes more.
Professor Asnly Mites, IN his experiments
with pigs found bat it REQ uirsd for the first
pound OF growth s pounds OF meal, for the
second period 4 O. pounds were required; the
third period required i % pounds; the fourth
5.24 pounds, snd the hfth period 5.06 pounds
of meal were required for one pound of
growth of live piss
With this evidence in favor of early ma
turity from such excellent sources, the trials
made by professor E. W. Stewart also gave
equally ss strong results in its favor He led
pigs, leg. inning at six weeks of age (forty-two
days. and continued for lie days, dividing
the time into three periods During the first
pericd O.s quarts of skim milk we're required
for one pound OF growth. The quantity, as
reported. is evidently a mistake, as it is too
small, for during the second period II. 3
quarts were needed, end fifteen quarts were
used during the third period, bat the second
and third periods, without noticing the
first, demonstrate that the older the
pig the greater the cost of growth.
In more than twenty trials the results
are the came, and Professor Stewart claims
that X is a Law that the Older and larger an
animal crows the more food is required 70
accomplish a given live WEIGHT gain. The
law prop bundled is indlspui a5le vet open ID
the question that something depends on size
rather than on sge. IL is both, for il will be
seen that late maturity prolongs the days of
feeding and necessiiatss the support OF the
animal more days than IS necessary. The
Professor thinks thar pig can be made TO
weigh go 0unos when seven months old,
and their average weigh. should be 125
pounds, while we now carry them over six
teen months at times The calculation is
based uI on the scales, aud is no delusion. A
very little grsin added to the little more
than msinTsnan fodder in the grass of the
pasture would carry shotes to market the
first sesson. and would be less than necessary
10 carly them needlessly through the winter
besides saving interest risk and good pzstur-
ing for steer or another pig as young pork
is the cheapest.
