Genital Abnormalities of Indian Cow and Buffalo
(c) Cystic degeneration of the ovary. Three ovarian
cystic degenerations were observed; all in the
buffalo. In specimen 1 (Plate XI, fig. 2) multiple
cysts entirely replaced the left ovary. The right
ovary was normal and functional. In specimen 2
(Plate XI, fig. 3 B, right hand extremity) the anterior
part of the ovary consisted of a single sac (25 mm.
diameter) containing coagulum. The sheath of this
cyst was continuous with the ovarian covering;
the ovary was nearly intact, but its stroma contained
a central cavity 4 mm. in diameter. The third
case simulated the second.
(d) Cysts of the corpus luteum. Luteal cysts were
noted in the cow and in the buffalo. Many corpora
lutea contain small central cavities (about 3 mm.
diameter) appearing as a parting between the whorls
of substance. It is difficult therefore to define
normality. In some of these cases, however, the
luteal body was thinly walled cavity frequently
containing a whitish coagulum. Table II gives
some comparative sizes of corpora lutea and their
cavities. Luteal cysts are to be seen in Plate
XI, Figs 4, A and C. In Plate XI, fig. 4 B, a. white
central coagulum can be observed.

This condition, it appears, is often associated
with other ovarian or tubular disease, e.g. embedded
and cystic ovaries.
Attempts were made to express cystic and normal
corpora lutea of buffaloes, but, except where the
natural protrusion was large, expression during life
without injury to the ovary did not seem feasible.
Cysts on other parts of the genitalia. Cysts on
buffalo's genitalia are very common on the uterine
wall, on the broad ligament, on the tubes or near
the ovaries. They vary from the size of a pea. to
a Brazil-nut, but do not appear to be of great im-
portance and their aetiology is unknown.
SUMMARY OF PART I
The macroscopic appearance of the genitalia of
the cow and buffalo differs considerably. The
uterus of the buffalo is larger and more turgid than
the cow's. It also has a peculiar blue and white
surface stippling. The fallopian tubes of this animal
are coarser and more embedded in the broad liga-
ments. The cow's ovaries are mottled and freely
mobile in a loose attachment, but the buffalo's
have a plain white surface and are more tightly
secured. The luteal cycle in the cow is notable
for its bright colour changes, whereas in the buffalo,
apart from hæmorrhage on the protrusion and a
remarkable red-veining, colour changes are almost
absent, and the background is always a subdued
greyish stone-white.
SUMMARY OF PART II.
Two common types of metritis have been described,
chronic and acute. The former was more prevalent
in the cow. Two cases of pyometra in the cow and
a case of tubercular metritis in the buffalo were
noted.
Cervicitis was rarely encountered in the buffalo
or cow but one case has been described and illustrated,
Abnormalities of the fallopian tubes were not
seen in the cow. But several were described in the
buffalo, five being unusual.
Ovarian abnormalities were rare in the cow, but
were relatively common in the buffalo. Especially
noteworthy were ovarian encapsulation, teratomata,
and cysts of the reproductive organs.
