Pl AN FOR BREEDING SOUND
COWS OFFERED BY EXPERTS

The Importance of absorption and
sterility in cows is rapidly becoming
more acutely felt by breeders and is
each year playing a more serious part
ir the national economy. BY inter-
fering more and more with the re-
productive powers of cows diseases
exert an unfavorable influence upon
the production of meat. milk and
dairy products, decreasing the sup
ply and increasing the cost.
Innumera BILE reasons have been as
signed to account for abortion and
sterility in cows. Abortion has been
regarded as the result of blows. gor-
ing. kicks, slips. falls, various feeds
water, drugs. etc, and finally when
the abortions are numerous to con-
tagion. Sterility has been attributed
also to a great variety of causes-to
the character of the feed or water, to
poverty, and overfatness, and, as with
abortion, when the cases are numer-
Gus, to contagion.
Veterinarians who have investigated
abortion IN COWS in recent years have
agreed that in a very large percent
age of cases it is due solely to con-
ia gion.
The United States Department OF
Agriculture. in cooperation with Cor
nell University, will shortly publish
a professional paper, Bulletin No. los
entitled 1.-THE Granular Venareal Dis
ease and Abortion in Cattle. This
disease may be defined as a chronic
infection of the genital tract of cat
tie, manifesting itself in the form OF
granular or nodular elevations in the
genital mucus membranes, chiefly OF

The report gives, in detail the re-
suits of a large number of examina-
tions of live cattle. supplemented by
large number of post -mortem ex-
aminations at slaughter houses These
examinations have shown the grann-
lar venereal disease to be present in
a large number of cases of abortion.
The conclusions of the author as
to the effect of this disease are as
follows:
Methods of Combating Abortion.
The granular venereal disease Of
cattle is, so far as known, universally
distributed. From clinical observa-
ton it has a vital relation to eonta-
eious abortion 1t is incurable in the
present state of our knowledge, but
may be greatly decreased in viru-
lence.
The ordinary if not sole avenue OF
the entrance of the infection of eonta
sious abortions is the genital canal
and the invasion antedates the sealing
of the uterus. which ordinarily occurs
within thirty days after conception,

edge little or nothing can be done 10
