The mummified fetus may remain in the uterus for months beyond normal gestation time or it may be expelled shortly before the expected end of the pregnancy. If you have a cow that appears to be pregnant after having been bred and the cessation of her heat cycles but approaches calving time with no evidence of being ready to calve and shows no signs of readiness i.e. no udder development, no relaxation of vulva etc., call your vet, and if she has a mummified fetus the vet can induce labor to expel it.
Hydrops amnii is the production of too much fluid around the fetus, and can occasionally occur in cows. The cow's belly may become large before it is time to calve. This condition is sometimes due to genetic abnormality resulting in a defective fetus. In severe cases the cow does not survive unless the pregnancy is terminated early. If you have a cow that looks as if it is going to have triplets, call your vet to examine her. In some cases labor must be induced and the thickened fetal membranes manually broken.
Prolapse of the vagina is a more common problem in pregnant cows and occurs a few weeks or even a month or more before calving. Some cows, especially Herefords, have a structural weakness that allows part of the vagina to prolapse during late pregnancy – this is an inherited problem and may be passed on by bulls that sire daughters that pass this tendency to their calves.
The primary cause of vaginal prolapse is pressure and weight of the large uterus in late pregnancy. When a cow lies down this pressure may cause vaginal tissue to prolapse. She may pass manure while lying there and strain a few times, and the tissue bulges out.
A mild prolapse is a bulge the size of an orange or grapefruit and usually retracts when the cow gets up. However, if she prolapses each time she lies down or strains, the tissue may be forced out still farther. Even a small prolapse may stimulate the cow to strain and this makes the situation worse, she has a mass of tissue bulging out, that becomes damaged, direct and quite possibly infected.
Because the vaginal wall is not a sterile environment infection is not the primary concern. The problem is that once these tissues are turned inside out, blood supply from the prolapsed area becomes restricted and makes the tissue swell. The longer it protrudes outside the body the more it swells and is harder to be put back. If the cow is approaching the time of calving, this swelling may make birthing more difficult. A VAGINAL PROLAPSE SHOULD BE PUSHED BACK AS SOON AS POSSIBLE, EVEN THOUGH THE CONDITION ITSELF IS NOT LIFE-THREATENING.
If the prolapse is large i.e. the size of a volleyball, the bladder may become involved causing inability to urinate until the prolapsed tissue is pushed back inside, she may strain
