Intrauterine fetal death may either end up in resorption or mummification. The later
event being common when the death of fetus occurs after ossification of bones has
begunandresorptioncannottakeplace.Thechancesincreasewiththeadvancement
of gestation stage. In cattle an incidence of 0.13 to 1.8% has been reported (Barth,
1986) and haematic mummification is common. Caruncular hemorrhage has been
incriminated to be the cause of fetal death, followed by resorption of fetal fluids
and thereafter the fetus, tightly covered by the membranes, being separated from
the uterine wall by a viscous mass of clotted blood; giving the uterus a doughy
feeling. However whether the inter-placental hemorrhage is the cause or the sequel
of fetal death remains unclear (Noakes et al., 2001). A genetic predisposition to
the condition has been described in Jersey, Guernesy, and Friesian cattle (Logan,
1973). Recently (Ghanem et al., 2005) investigated the genetic factors in 10
fetal mummies and reported a factor XI gene deficiency, in 2 of these fetuses
was heterozygous. Although umbilical cord torsion has also been suggested as
a possible cause, this has not been a consistent finding. Hormonal causes have
also been suggested (Gorse, 1978). With the absence of concomitant luteolysis,
the fetal mummy is indefinitely retained in the uterus in a sterile environment,
with the condition being diagnosed when animals are examined for prolonged
gestation. Whereas single mummified fetuses have been widely reported, the
present paper records a rare case of mummified twins in a HF X local cross and a
case of abortion following fetal mummification at about 3 months gestation in two
HF x local crossbred cows. Most veterinarians are agreed that the fetal mummy is
indefinitely retained in a sterile uterine environment, indefinitely. However, Hafez
and Hafez (2000) also reported abortions in early stages of mummified bovine
fetuses. The present paper reports two cases of haematic fetal mummification in
HF X local crossbred cows, one with twins delivered through caesarean section
and the second having aborted at about four months.
Case Reports
A 5 year old cow (local X HF cross), in her fist lactation, was reported to have
overshot her gestation by about a month, without showing any signs of approaching
parturition. The animal was in good body condition, eating and drinking normally,
with no clinical signs of illness. Physiological parameters like body temperature,
pulse and respiration were in the normal range.
Clinical examination revealed the presence of an enlarged uterus, in front of the
pelvic brim, with no fetal fluids, a tightly contracted uterus over the fetus, along
with the presence of a doughy mass in between the uterine wall and fetus. Further,
careful examination lead to palpation of the right eye orbit of the fetus, but the
