KNOWLEDGE ESSENTIAL TO FoRECAs,
VALUE OF BULL.
Dsirymen have paid q great deal o
attention to breeding for increased mill
production. The medium through which
this has chiefly been done is the system
Of advanced registry" Now there is I
fundamental difference in principle II
the method by which cows are put into
The advanced registry, and that by which
bulls are entered. A cow Is put intt
the advanced registry if she is higt
mixer; her production, in itself, il
taken as sufficient evidence to enroll hel
in list of animals, of which the pre-
sumption Is that they are good animals
to breed from to get increased produc
tiveness. Obviously the male cannot b'
enrolled on such basis. So he is pu
into the advanced registry on the basis
of the performance of his daughters
II be has certain number of daughters

registry. 1t will be recognized at once
that in the method of entering the cows
in the advanced registry the cattle clubs
are proceeding on the theory Of breed
ing which was at the basis of the mass
selection experiment to improve egg pro-
duction at the Maine Agricultural Ex-
pertinent Station. This experiment, II
will be recalled, signslly failed to bring
out any improvement. In the method
of entering bulls in the advanced regis
try, on the other hand, the procedure is
strictly in accord with that plan of breed
ing which, since 1907, has led to such
excellent results with egg production q,
| the Maine Station, namely, the plan
which is based on tested progeny. Bulls
get into advanced registry on the basis
of their demonstrative ability to get
high producing daughters. Cows go in
simply because they milk well.
These facts clearly point to the prog,
eny test for the transmitting qualities OF
herd sires as the proper method of i'm
proving the herds production per cow.
The analysis of the progeny test has now
been completed by the Maine Agricul-
tursl Experiment Station for the Guern-
sey breed and for the Jersey breed in so
far as the data necessary are available
in the advanced registries. As rapidly
as the funds permit the same information
on the Holstein-Friesian breed is being
obtained.
The "prepotency'' of certain of the
Jersey sires may be cited. There are
224 Jersey Registry of Merit sires which
meet the requirements of this perform
ance test for their transmitting qualities
in milk production. One hundred and
five of these sires or less than one-half

ters over that of the dams Of these
daughters. The largest number OF
