milk production OF his daughters on
the average 2s20l pounds. Among
the other sires standing well upon
the list might be mentioned Queens
Raleigh. ss2s2; Sans Aloi, s1o12;
Ternisia's Interested Prince, 1858:
The Plymouth Lad, s97e2; and Chief
4714S.
are included in the sires which met
the requirements Of the daughter
dam performance test for transmit
ting qualities Of butter-fat percent
age. Out OF this number 101 sires
raised the .butter-fat percentage Of
their daughters milk as compared
with the butter-fat percentage of the
dams Of these daughters. The lead
ing sire in this butter-fat percent
age performance test was Clear
Brook Chief 74e85 raising his daugh-
ter on the average 1888 per cent. OF
butter-fat. This sire had two daugh-
ter-dam pairs. The dams were both
in the lowest group for butter fat
percentage (class d. and this sire
raised his daughter from these dams
to the highest group (class Al.
Among the sires with a fair number
of daughter-dam pairs which raised
the butter-fat percentage to mark
ed degree night be mentioned, Irenc's
King Pogis 1882; Merry Maiden's
Grandson 71003: Pogis 18th Of Hood
Farm 94501; Jacobs Emanon S4177;
and Golden Ferns Son 7S6S7. Hood
Farm Pogis 9Th leads in number Of
daughter dam pairs with AZ. This bull
raised the butter-fat percentage OF
his daughter on the average Of 0.243
per cent. over the butterfat per-
centage Of the dams OF their daugh-
tiers.
The sires mentioned as superior in
the milk transmitting ability, Hood
Farm Torono and Spermfleld Owl. I'D
not check up SO we'll in their ability
to transmit high butter-fat percent
age. Hood Farm Torono caused mis-
daughters on the average to be 0.225
per cent. Of butter-fat below what
the dams Of these daughters pro-
duced. Spermf1eld Owl only raised
his daughters on the average 0027
per cent. of butter-fat over what the
dams Of these daughters produced.
There are 224 sires Of known trans
hitting ability for net butter-fat Civ
en-. OF this number only 80 sires
raise the butter-fat production of
their daughters over that OF their
dams. The sires which raised the
production of their daughters but
ter-fat most were Sans Aloi S1012,
Signal Successor 7275S. and Golden
Glow Chief 61460. The sires which
made the deepest impression on the
breed by raising the butter-fat OF
the largest number of daughters over
that of their dams was Hood Farm
Torono with "a pairs and an average
increase for each daughter Of 121.o1
pounds. The. next bull, Spermfieid
Owl. with &c pairs raised the but
ter-fat production 97.71 pounds on
the average of each Of his daughters.
Some Of the bulls lowering the pro-
duction of their daughters markly
we're Gertie's Son of Washington
Ss79s, Hood Farm S. Tormentor 96S11,
and oxford Lads Owl 1889.
The information summarized above
was arranged to reveal the trans
hitting qualities for milk produce
ton. butter-fat percentage and but.
ter-fat Of Jersey sires to their sons.
There were in this table 159 slres
which had sons whose progeny per-
Torrance was known. OF this num-
Der 50 or Significantly less than half
had sons who raised the butter-fat
production Of their daughters over
that of their dams. Among these
sires who had sons of merit Signals
Crown Prince 1881 and Chief Engi-
neer 4714s are the leaders. Among
those sires whose sons lowered the
butter-fat productions Of their
daughters may be mentioned Merry
Maiden's grandson 91003 and Etheel
EDS Jubilee 1929.
The sires of superior merit are de-
fined as those which raise the milk
Of their daughters as compared with
that of their dams. The inferior
sires are defined as those sires who
lower the milk production and but
ter-fat percentage Of their daughters
as compared with the same variables
in their dams. There are g sires
in the group Of sires superior in their
transmitting qualities for milk pro-
duction and butter-fat percentage.
In the group Of sires inferior in their
transmitting ability for these two
characters there are II sires, ratio
of to 1t. Such a difference speaks
for itself. It emphasizes with start
ling clearness the need Of exact
knowledge Of the transmitting quail
ties Of bulls to be bred as sires and
Of the necessity for exact knowledge
Of the Inheritance Of milk produc-
ton and butter-fat percentage. In
fact the sire whose performance test
is known is only good as long as
he lives and with his death dies the
value Of his test. This would not be
so II the way in which high milk or
butter-fat are transmitted from sire
to daughter were known, for by the
application Of tese rules, once dis .
covered. 1t would be possible to pro-
duce from that sire. sons or daugh-
tiers whose progeny performance
would be known when they were
born. 10 have the progeny test on
these sires Of lasting value it is con-
sequently necessary to obtain the
facts Of milk production inheritance
the Maine station Is trying to do
through the agency Of the carefully
controlled matings Of high and low
milking animals.
