This Is a True Emergency, and Every Minute Counts
Uterine prolapse is one of the most dramatic and life-threatening emergencies in cattle production. When the uterus turns inside out and protrudes from the cow's body after calving, you have to act fast to save her life. This condition demands rapid recognition, proper first aid, and veterinary intervention.
This guide covers identification, emergency response, what to do while waiting for the vet, treatment, and prevention strategies.
Understanding Uterine Prolapse
What Is Happening
During or shortly after calving, the cow strains and the uterus inverts and pushes outward. First the uterine body and then the horns turn inside out, producing a large mass of red or pink tissue hanging from the vulva. The placenta may still be attached to the exposed surface.
When It Occurs
Uterine prolapse most commonly occurs during delivery of the placenta. It rarely happens more than 24 hours post-calving and almost never occurs in non-pregnant cattle. If you check your calving cows within the first few hours after delivery, you will catch most cases early.
Recognition
Visual Identification
The prolapsed uterus appears as red to dark red tissue (which may darken further with time) hanging from the vulva. Look for the distinct "button-like" structures called caruncles on the surface, as these confirm you are looking at uterine tissue. The placenta may still be attached, and the mass is often bloody and covered with debris from the ground.
Distinguishing from Other Conditions
| Condition | Appearance |
|---|---|
| Uterine prolapse | Large red mass, caruncles visible, hangs well below hocks |
| Vaginal prolapse | Smaller, pink, smooth surface, occurs before calving |
| Retained placenta | Membranes hanging, no large tissue mass |
| Rectal prolapse | From anus, different tissue appearance |
Emergency Response
Immediate Actions
This is not a "wait and see" situation. Call your veterinarian immediately, describe what you see, and follow any instructions given over the phone. Have someone continue first aid while another person makes the call.
Keep the cow standing if possible, and minimize her movement and straining. Cover the exposed tissue with a clean, wet towel or sheet and keep it moist with clean water. Prevent further contamination and protect the tissue from damage (the cow lying on it, other animals stepping on it). Use bedding to cushion the area and keep other animals away from her.
What NOT to Do
- Do not tie weights to try to keep it from prolapsing further
- Do not allow the tissue to dry out
- Do not wash with soap or harsh chemicals
- Do not let her lie on it unprotected
- Do not ignore it, as this is always an emergency
While Waiting for Veterinarian
Keeping Tissue Viable
Use warm water (not hot) for moistening and protect the tissue from freezing in winter. Clean water is essential, and saline solution is ideal if you have it available. Rewet towels or sheets regularly to prevent drying. Keep the cow from standing on the tissue and keep manure, dirt, and debris away from the exposed surface.
Positioning the Cow
If she is lying down, position her so the uterus is supported rather than compressed underneath her. Slightly uphill positioning with the hindquarters higher may help reduce the weight of the prolapse pulling outward. Support the prolapse on clean material and monitor for signs of compromised circulation in the tissue.
Reducing Straining
Continued straining can tear blood vessels, makes replacement more difficult, and exhausts the cow further. To minimize straining, reduce handling as much as possible and provide a dark, quiet environment if you can. Epidural anesthesia to stop the straining reflex is a veterinarian-only procedure, which is another reason to get the vet there quickly.
Risk Factors
Predisposing Conditions
| Factor | How It Contributes |
|---|---|
| Hypocalcemia (milk fever) | Weak uterine tone, straining |
| Difficult calving | Exhaustion, trauma, excessive straining |
| Excessive traction | Forces uterus outward with calf |
| Large calf | More straining required |
| Multiple calves | Stretched, weakened uterus |
| Retained placenta | Continued straining |
| Standing on incline | Gravity effect |
| Poor body condition | Weakened muscles |
| Excessive condition | Fat deposits reduce muscle support |
Breed and Individual Factors
Older cows, cows with a previous prolapse, and certain breeds (which vary by study) are at greater risk. If a cow has prolapsed before, she should be flagged as high-risk for every subsequent calving.
Veterinary Treatment
The Replacement Procedure
The veterinarian will begin by administering an epidural to eliminate straining and reduce pain, which is essential for safe replacement. Next comes cleaning the uterus by gently removing debris and washing the tissue, while assessing its viability.
If the tissue is swollen, the vet may apply sugar (which creates an osmotic effect to draw out fluid) or use compression wrapping and allow time for swelling to go down. Replacement starts with the portion nearest the vulva and works systematically inward, making sure both uterine horns are fully returned and the organ is back in its normal position.
To prevent immediate re-prolapse, the vet typically places a Buhner suture to close the vulva partially, and may use other retention devices as well. Post-replacement treatment includes antibiotics to prevent or treat infection, anti-inflammatories for pain and swelling, calcium if hypocalcemia is suspected, and IV fluids if the cow is in shock.
Post-Treatment Care
In the first 24 hours, monitor for re-prolapse and watch for signs of shock. Follow all veterinary instructions carefully. During the first week, provide easy access to water and feed, continue medications as prescribed, and take the cow's temperature regularly to catch infections early. Over the longer term, monitor for infection, assess overall recovery, and discuss future breeding decisions with your vet.
Prognosis and Outcomes
Survival Rates
With prompt treatment, most cows survive a uterine prolapse. Many can be bred again, though some have a higher risk of recurrence.
| Factor | Good Prognosis | Poor Prognosis |
|---|---|---|
| Time from prolapse | Found immediately | Hours delayed |
| Tissue condition | Clean, viable | Damaged, necrotic |
| Cow's condition | Alert, stable | Shock, weak |
| Treatment | Prompt, skilled | Delayed, improper |
| Complications | None | Hemorrhage, infection |
Future Fertility
Some cows experience reduced fertility after a prolapse. The recurrence risk on the next calving runs 10 to 20%, so breeding decisions should weigh the cow's value against that risk.
Prevention Strategies
Pre-Calving
Proper nutrition before calving is the first line of defense. Manage calcium metabolism carefully, supplement selenium and Vitamin E, and maintain a balanced mineral program. For cows identified as high-risk (previous prolapse, older age, twins), consider calcium supplementation right at calving time and monitor them more intensively.
During Calving
Select bulls that produce moderate-sized calves for your cow herd. Provide timely, appropriate intervention during difficult calvings, and avoid using excessive force when assisting. Allow time for natural progression before intervening, support the calf as it delivers rather than letting it drop, and stop pulling if you encounter unusual resistance.
Post-Calving
Check freshly calved cows for early signs of milk fever, since hypocalcemia weakens uterine tone and increases prolapse risk. Provide good footing and calm, low-stress handling during the recovery period.
Recurrence Risk
Managing Previous Prolapse Cows
The decision to breed a cow that has prolapsed before requires careful thought. The recurrence risk is real, and if you choose to breed her again, have your veterinarian on standby at calving time. Consider preventive suturing before calving and plan for immediate intervention if the prolapse recurs.
Genetic Considerations
If you see multiple prolapse cases in a family line, consider culling. Don't keep replacement heifers from affected cows, as there appears to be a genetic predisposition in some lines.
Emergency Preparedness
What to Have on Hand
Keep a large bucket for clean water, posted phone numbers for your vet and a backup vet, a headlamp or flashlight for night checks, and access to a headgate for containing the cow. Know your vet's after-hours contact information, review basic first aid steps before calving season starts, and know where your calving cows are at all times during the season.
