Retained Placenta in Donkeys
- See your vet immediately if a jenny has not passed the placenta within about 3 hours after foaling, or sooner if she seems painful, weak, feverish, or depressed.
- Retained placenta can lead to metritis, endotoxemia, laminitis, and death if treatment is delayed.
- Do not pull on hanging membranes. Their weight may help separation, but forceful traction can tear tissue and leave pieces behind.
- Common treatment options include prompt exam, oxytocin, anti-inflammatory medication, antibiotics when indicated, and close monitoring for fever, discharge, and hoof pain.
- Typical 2025-2026 US cost range for veterinary care is about $250-$700 for straightforward farm-call treatment, $700-$1,800 for more involved medical management, and $1,800-$4,500+ if hospitalization or intensive care is needed.
What Is Retained Placenta in Donkeys?
Retained placenta means the fetal membranes have not been fully expelled after foaling. In equids, this is treated as a true postpartum emergency because retained tissue can quickly trigger uterine infection, toxin release, and painful hoof inflammation called laminitis. Most guidance for donkeys follows equine postpartum medicine, because donkey-specific research is limited and the same major risks apply.
In practical terms, if your donkey still has membranes hanging from the vulva several hours after birth, your vet should be contacted right away. The placenta should be saved for inspection once it passes, because missing pieces can mean part of it is still inside the uterus.
This condition is not something to watch for a day or two at home. Early treatment often focuses on helping the uterus contract and empty safely while reducing the risk of infection and endotoxemia. Fast action can make a major difference in comfort, recovery, and future fertility.
Symptoms of Retained Placenta in Donkeys
- Placenta or membranes still hanging from the vulva more than 3 hours after foaling
- Only part of the placenta passed, or the passed placenta looks torn or incomplete
- Foul-smelling, dark, or excessive vaginal discharge
- Fever, depression, reduced appetite, or lethargy after foaling
- Colic signs such as pawing, looking at the flank, restlessness, or repeated lying down
- Reluctance to walk, shifting weight, hot feet, or strong digital pulses that may suggest laminitis
- Continued straining after delivery
Some donkeys show only a visible piece of hanging membrane at first, while others become sick quickly. Worry increases if the placenta has not passed by about 3 hours, if your donkey develops fever or colic, or if she seems sore in the feet. See your vet immediately if any of these signs are present, because complications can escalate fast.
What Causes Retained Placenta in Donkeys?
Retained placenta happens when the normal separation between the uterus and fetal membranes does not occur promptly after birth. In equids, the nongravid horn is a common place for tissue to remain attached. Even when only a small portion is retained, that tissue can act as a source of inflammation and infection.
Risk factors can include difficult delivery, uterine fatigue, twins, abortion or premature delivery, stillbirth, placentitis, and trauma or heavy manipulation during foaling. Any situation that stresses the uterus or interferes with normal postpartum contractions may raise the risk.
Some cases occur without an obvious cause. Because donkey-specific data are sparse, your vet may use horse-based postpartum guidelines while also adjusting for the individual donkey, her size, her foaling history, and how sick she appears.
How Is Retained Placenta in Donkeys Diagnosed?
Diagnosis starts with timing and a postpartum exam. If the placenta has not passed within about 3 hours after foaling, your vet will usually treat that as abnormal in an equid. They may assess your donkey's temperature, heart rate, hydration, attitude, uterine tone, vaginal discharge, and signs of pain or early laminitis.
Your vet may also inspect the passed membranes to see whether they are complete. This matters because a torn placenta can mean a tip or horn is still inside the uterus. In some cases, your vet may perform a careful reproductive exam or ultrasound to look for retained tissue, fluid, or signs of metritis.
Bloodwork is not always needed in mild cases, but it can help in sicker donkeys. A CBC, chemistry panel, and inflammatory markers may be used to look for infection, dehydration, endotoxemia, or organ stress. The goal is not only to confirm retained tissue, but also to catch complications early so treatment can be matched to the donkey's condition.

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 placenta been retained long enough that treatment should start now?
- Does the placenta look complete, or do you suspect a piece is still inside the uterus?
- What signs of metritis, endotoxemia, or laminitis should I watch for over the next 24 to 72 hours?
- Is oxytocin appropriate for my donkey, and how soon should it work?
- Does my donkey need antibiotics, anti-inflammatory medication, or hoof support?
- Should we do an ultrasound or other diagnostics to check for retained tissue or uterine fluid?
- What home monitoring schedule do you want for temperature, appetite, manure, discharge, and foot comfort?
- How might this affect future breeding or fertility?
How to Prevent Retained Placenta in Donkeys
Not every case can be prevented, but good foaling management lowers risk. Close observation during late pregnancy and foaling helps your vet respond quickly if there is dystocia, placentitis, twins, or an abnormal delivery. A clean foaling area, good nutrition, and routine prenatal care also support normal postpartum recovery.
After birth, the placenta should be monitored carefully and kept for inspection once passed. Do not cut off hanging membranes close to the vulva and do not pull on them. If your donkey has a history of difficult foaling or postpartum complications, ask your vet ahead of time what timeline should trigger an urgent call.
The most effective prevention of serious complications is early recognition. In equids, waiting too long is the biggest problem. A prompt call to your vet when the placenta is still present at about 3 hours postpartum can help prevent metritis, endotoxemia, and laminitis.
