A goat miscarriage typically involves the unexpected delivery of a dead fetus, often accompanied by bloody or discolored vaginal discharge, and sometimes visible placental tissue. Depending on when in the pregnancy it happens, the fetus may look fully formed or partially decomposed, and the placenta can range from normal-looking to covered in thick, discolored material. Knowing what to expect helps you act quickly to protect the doe, the rest of your herd, and yourself.
What You’ll See During a Miscarriage
The most obvious sign is the delivery of a fetus before the normal 150-day gestation is complete. If the loss happens in late pregnancy (the last month or so), the kid often looks fully formed and may appear fresh, as though it could have been born alive. In mid-term losses, around the fourth month, the fetus is smaller and less developed. Earlier losses can be harder to notice because the tissue is small and may be consumed by predators or scavengers before you find it.
In some cases, the fetus is partially decomposed (referred to as “autolyzed”), meaning the tissue has begun breaking down before delivery. This happens when the fetus dies in the uterus but isn’t expelled right away. An autolyzed fetus will appear discolored, soft, and may have a strong odor. Occasionally, a fetus that dies much earlier can mummify inside the uterus, appearing dried and shrunken when eventually passed.
The doe herself will usually show vaginal discharge that can range from bloody to brownish or yellowish. She may appear restless, separate from the herd, vocalize, strain, or stand with an arched back. Some does show very few behavioral signs before you find the expelled fetus.
What the Placenta Looks Like
The placenta is one of the most telling pieces of evidence, and its appearance varies depending on the cause of the miscarriage. With some infections, the placenta looks essentially normal. In other cases, it’s visibly inflamed. Chlamydia, one of the most common causes of goat abortion, produces a placenta covered in a reddish-brown discharge across both the button-like attachment points (cotyledons) and the tissue between them. Q fever, caused by the bacterium Coxiella burnetii, creates a gray-brown coating on the placenta with noticeably thickened tissue.
Sometimes the placenta is not passed at all. A retained placenta, one that stays inside the doe for more than 12 hours after delivery, is a serious complication that can lead to uterine infection. If you see membranes hanging from the doe but nothing fully expelled, that’s a sign she needs veterinary attention.
Common Causes of Goat Miscarriage
Roughly three out of four diagnosed abortion cases in goats and sheep trace back to two bacterial infections: Chlamydia abortus and Coxiella burnetii (the organism behind Q fever). These are by far the leading infectious causes. Other pathogens include Brucella (which tends to cause mid-term losses around the fourth month), Listeria, Toxoplasma gondii (a parasite), Campylobacter, and Salmonella. Caprine herpesvirus 1 causes late-term losses where the fetus may look fresh with no visible abnormalities, making it harder to identify without lab testing.
Not all miscarriages are caused by infection. Nutritional deficiencies are a significant and often overlooked trigger. Copper deficiency during pregnancy increases rates of abortion and stillbirth, and aborted fetuses from copper-deficient does have been found with brain tissue damage. Selenium deficiency is linked to heart tissue damage in aborted fetuses. Deficiencies in vitamin A, vitamin D, phosphorus, zinc, and iodine all raise the risk of pregnancy loss. Low-iodine diets in particular, below 0.5 micrograms per kilogram of body weight daily, lead to higher abortion rates. Poor pasture quality from drought or overgrazing is a common underlying factor, since it reduces the mineral content of forage.
Why You Should Not Handle Tissues Bare-Handed
Several of the organisms that cause goat miscarriage can infect humans. Brucella melitensis, the strain that primarily affects goats, spreads through direct contact with infected blood, placentas, fetuses, and uterine secretions, as well as through raw milk. Coxiella burnetii causes Q fever in people, which can produce flu-like illness and, in rare cases, chronic complications. Chlamydia abortus poses a particular risk to pregnant women, potentially causing miscarriage in humans as well.
Always wear gloves when handling aborted material. Avoid touching your face, and wash your hands and arms thoroughly afterward. If you are pregnant, do not handle goat birthing materials or aborted tissues at all.
What to Do After a Miscarriage
Isolate the doe from the rest of the herd immediately. The fluids and tissues from a miscarriage can be highly infectious to other pregnant goats. Clean or remove any contaminated bedding from the area where the abortion occurred.
Collect both the fetus and the placenta if possible, and refrigerate them (do not freeze) until you can get them to a veterinary diagnostic lab. The placenta is actually a better diagnostic sample than the fetus itself. If the placenta isn’t available, your vet may be able to collect a tissue sample from inside the uterus. Contact your vet before submitting samples so you know exactly what to send and how to package it. A blood sample from the doe is also typically requested. Identifying the cause matters not just for this doe but for preventing a wave of losses across your herd.
Caring for the Doe Afterward
Most does recover well from a miscarriage with proper monitoring. Watch for signs of retained placenta, ongoing vaginal discharge with a foul smell, fever, lethargy, or loss of appetite, all of which suggest uterine infection. Infections of the uterus (metritis) following a retained placenta or prolonged labor require antibiotic treatment from your vet.
In rare cases, more serious complications develop. Small tears in the uterus can occur, especially if the doe had difficulty passing the fetus. Uterine prolapse, where the uterus partially turns inside out and protrudes, can happen after a difficult delivery but has a good outcome when caught and treated early. The most dangerous post-miscarriage complication is colonization of the uterus by clostridial bacteria, which can cause a rapidly fatal toxemia requiring aggressive emergency care.
Keep the doe in a clean, dry area with good nutrition and fresh water. Monitor her temperature and appetite daily for at least a week. Most does that miscarry from a one-time cause can breed successfully in following cycles, but does that miscarried due to infection like chlamydia may shed the organism again during future pregnancies and pose a risk to other herd members.
Reducing the Risk in Your Herd
Prevention starts with nutrition and biosecurity. Ensure your goats have access to a quality mineral supplement that covers copper, selenium, zinc, iodine, and phosphorus, adjusted for your region’s soil deficiencies. Vitamin D levels depend partly on sunlight exposure, so goats kept indoors or in heavily shaded areas during winter may need supplementation.
For infectious causes, vaccines exist for some but not all pathogens. Brucellosis vaccination in goats is regulated at the state level and can only be administered by state or federal veterinary officials, so check with your local APHIS office for requirements. A vaccine against Toxoplasma gondii is available for sheep and is sometimes used in goat herds. There is currently no proven effective vaccine for border disease virus in small ruminants.
Quarantine any new animals for at least 30 days before introducing them to pregnant does. If a doe in your herd miscarries, isolating her and testing for the cause protects the rest of the group. In herds that experience multiple abortions in a season, a pattern often points to an infectious agent moving through the flock, making diagnostic testing especially important.
