Salpingitis, if diagnosed definitely, is not worth treating. It is best to
fatten the animal for the butcher. The condition may be unilateral but it usually
tends to be bilateral. Mild infections may spontaneously improve when
the concurrent metritis is suitably treated. When salpingitis is suspected
never try to dislodge a persistent corpus luteum as there is danger of infection of
the crater from the pavilion of the oviduct. If the condition is unilateral, Williams
recommends ovario-salpingectomy. Conklin, who has used Robin's carbon
dioxide apparatus to determine the patency of the Fallopian tubes in heifers in
which there was no other clinical evidence which might account for sterility, found
that in a few cases heifers conceived after passing the gas through the tubes.
Ovarian cysts may be ruptured per rectum. If that be not possible, it may
be tried per vaginam the walls of which are comparatively stronger and, therefore,
more force can be applied. If still no success, which happens when a cyst is deeply
situated, then puncture with a trocar per rectum (Plate XXIX, Fig. 4) or per
vaginam. These cysts are likely to refill after some time, so the operation may
have to be repeated after a few weeks' interval. In cases of only one ovary being
involved with a bad cyst or a tumour ovariotomy may be performed. When
there is a persistent corpus luteum, it should be dislodged per rectum (Plate XXIX,
Fig. 3) or per vaginam. Treat concurrent conditions of the other parts of the
genital tract. If there are signs of perioophoritis with adhesions to the surroun-
ding tissues or tumours are present in both the ovaries, the case is permanently
sterile and is beyond all hope of recovery.
In cases of functional sterility, bone-meal, flour and cod-liver oil should be
given in addition to a well balanced nutritious corn ration and plenty of green
fodder. Exercise is also essential. Turn the animal loose with the bull because
cases of " silent heat " which may not be detected by man will probably be detected
by the bull and covered. Theelin (Parke Davis & Co.) which is ovarian follicular
hormone extract, can be used both as pessaries and injections (5 c.c. twice with
four days' interval) along with the administration of Thyroid extract in food.
In cases where functional sterility has resulted from disuse atrophy of the
uterine mucosa and cotyledons, good results are claimed with wheat germ oil
which contains vitamin E. It may be given in doses of 25 c.c. intramuscularly
prior to service and at intervals of 6 to 7 days for six weeks afterwards or till con-
ception is clinically diagnosed.
Corpus luteum extract has been used in bitches to maintain pregnancy but is
expensive to use in cattle practice.
Grafting of ovaries has been recommended by various authorities, but its ap-
plication requires judgment and care. It is more successful in cows which have had
calves, but are sterile due to endocrine deficiency and not to any inflammatory
condition of the genital tract. In heifers that have never been pregnant and have
not shown clinical signs of oestrum and where there is no evidence of ovulation
on rectal examination, it is not likely to be of value. The donor should be a heifer
