Retained Placenta in Donkeys: Warning Signs, Risks & Urgent Care
- In donkeys, a placenta still present more than about 3 hours after foaling should be treated as urgent.
- Visible membranes hanging from the vulva are the obvious sign, but a small retained piece may be hidden and still dangerous.
- Major risks include metritis, endotoxemia, laminitis, fever, depression, and death if treatment is delayed.
- Do not pull on the placenta. Keep your jenny quiet, prevent her from stepping on the membranes, and call your vet right away.
- Typical 2025-2026 US cost range for on-farm evaluation and initial treatment is about $300-$900, with hospital-level or complicated care often reaching $1,000-$3,500+.
Common Causes of Retained Placenta in Donkeys
Retained placenta means all or part of the fetal membranes did not pass after foaling. There is limited donkey-specific published guidance, so your vet will usually manage this problem using established equine postpartum principles. In mares, membranes not passed within about 3 hours are considered retained, and that same urgent approach is reasonable for donkeys because the main dangers are the same: uterine infection, endotoxemia, and laminitis.
The exact cause is not always clear. Risk can rise after a difficult birth, twins, placentitis or other placental inflammation, premature delivery, stillbirth, uterine exhaustion, or heavy handling of the reproductive tract during foaling. A history of retained placenta in a previous pregnancy may also increase concern for recurrence.
Sometimes the whole placenta is still attached and hanging from the vulva. Other times only a small piece remains inside the uterus, especially near the non-pregnant horn, so the problem is easier to miss. That is why your vet may want to examine the passed placenta carefully or examine the uterus if the placenta looks incomplete.
Do not assume a donkey is safe because she seems bright right after foaling. Some equids look fairly normal at first, then become sick as toxins and uterine infection develop over the next several hours.
When to See the Vet vs. Monitor at Home
See your vet immediately if the placenta has not fully passed by about 3 hours after foaling, if membranes are hanging from the vulva, or if you are not sure whether the placenta is complete. This is not a wait-and-see problem once that time window has passed. The risk is not only local uterine infection. Retained membranes can trigger systemic illness and laminitis, which can become life-threatening fast.
Urgent warning signs include fever, depression, reduced appetite, colic signs, straining, foul-smelling discharge, fast heart rate, weakness, or reluctance to walk. Any heat in the feet, shifting weight, or a stiff stance after foaling is especially concerning because laminitis can follow postpartum toxemia.
Home monitoring is only appropriate while you are waiting for your vet and only if your donkey is otherwise stable. Keep her in a clean, quiet area with water available. If membranes are hanging, you can tie them up in a loose knot to keep them off the ground and reduce tearing or contamination, but do not cut them off and do not pull.
If the placenta appears to have passed, you should still monitor closely for the next day or two. Call your vet if the placenta looks torn or incomplete, or if your donkey develops fever, lethargy, reduced milk production, foul discharge, foot soreness, or any change in attitude.
What Your Vet Will Do
Your vet will start with a postpartum exam, including temperature, heart rate, hydration, gum color, uterine discharge, and foot comfort. They may inspect the placenta if it has passed, because even a small missing piece can matter. If part of the placenta is still present, your vet may assess whether it is complete retention or only a retained fragment.
Treatment often focuses on helping the uterus clear the membranes while reducing the risk of toxemia and laminitis. Depending on the case, your vet may use low-dose oxytocin, gentle uterine techniques, pain control, anti-inflammatory medication, and broad-spectrum antibiotics if infection risk is significant or retention has lasted longer. In equine practice, forceful manual pulling is avoided because it can tear membranes and damage the uterus.
Some donkeys need bloodwork, ultrasound, uterine lavage, IV fluids, cryotherapy or other laminitis prevention steps, and repeated rechecks over the next 12 to 48 hours. If your donkey is systemically ill, has severe metritis, or is not responding to field treatment, your vet may recommend referral to an equine hospital.
Your vet will also consider the foal. A sick postpartum jenny may nurse less, stand less, or become distracted by pain, so the foal may need monitoring for nursing success, hydration, and normal bonding.

Questions to Ask Your Vet About Retained Placenta in Donkeys
Bring these questions to your vet appointment to get the most out of your visit.
- Has the entire placenta passed, or do you suspect a retained piece is still inside?
- How long has this been retained, and how does that change the risk of metritis or laminitis?
- Is my donkey stable enough for on-farm treatment, or do you recommend referral?
- What medications are you using, and what side effects should I watch for at home?
- Does my donkey need antibiotics, bloodwork, ultrasound, or uterine lavage?
- What early signs of endotoxemia or laminitis should make me call you back immediately?
- How should I monitor the foal if the jenny is painful, weak, or not nursing well?
- What follow-up exam or recheck timeline do you recommend over the next 24 to 48 hours?
Home Care & Comfort Measures
Home care does not replace veterinary treatment for a retained placenta. Your role is supportive while your vet is on the way and during recovery afterward. Keep your donkey in a clean, dry, quiet space with fresh water and easy access to hay unless your vet gives different instructions. Limit stress and watch both the jenny and foal closely.
If membranes are hanging, keep them from dragging in bedding or manure. A loose knot can help shorten them, but do not tug, twist, or cut them off. Pulling can tear the placenta and leave infected pieces behind, or injure the uterus.
After treatment, monitor temperature, appetite, manure output, milk production, attitude, vaginal discharge, and comfort when walking. Check for shifting weight, reluctance to move, or warm painful feet, because laminitis can follow postpartum toxemia. Keep a written log so you can give your vet clear updates.
Call your vet right away if your donkey becomes dull, stops eating, develops a fever, has a foul odor, shows colic signs, seems weak, or the foal is not nursing normally. Early rechecks matter with this condition, even when your donkey seems improved.
