Calving Problems: When to Pull and When to Call the Vet

The Most Important Skill in Cow-Calf Production

Every calf that is born alive and healthy starts generating revenue. Every calf that dies during delivery is a total loss — the feed, the breeding costs, the year of maintenance on that cow, all of it gone. Dystocia (difficult birth) is the leading cause of calf death in the first twenty-four hours of life and a major cause of cow death and reproductive failure in beef and dairy operations. Knowing when to step in and when to step back during calving is arguably the most valuable skill a cattle producer can possess.

I have pulled more calves than I can count, and I have also been called to far too many situations where someone waited too long to intervene and the calf was already dead, or where someone intervened too aggressively and injured both the calf and the cow. The goal of this article is to draw a clear line between what you can handle on the ranch and what needs a veterinarian.

Normal Calving: Know the Timeline

Before you can recognize a problem, you need to know what normal looks like. Calving is divided into three stages, each with a predictable timeline.

Stage 1: Cervical Dilation (2 to 6 Hours)

The cervix is dilating, the uterus is beginning rhythmic contractions, and the calf is rotating into position for delivery. The cow will be restless, isolate herself from the herd, get up and lie down repeatedly, and may show mild signs of discomfort — swishing her tail, looking at her flank. She is not actively straining. This stage is longer in first-calf heifers (up to six hours) than in experienced cows (two to four hours). Many producers never see Stage 1 because it can happen overnight or while the cow is out on pasture.

You do not need to intervene during Stage 1. Leave the cow alone. Hovering over her will slow the process. Your job at this point is to note the time so you can track how long she has been in labor.

Stage 2: Fetal Expulsion (30 Minutes to 2 Hours)

This is active labor. The water bag (amniotic sac) appears at the vulva and ruptures, and the cow begins forceful abdominal straining (you will see visible, powerful contractions of the abdominal muscles). In a normal delivery, you should see two front feet (soles facing down) followed by the nose resting on the legs within thirty minutes to an hour after the water bag appears. The calf should be delivered within thirty minutes to two hours of the onset of active straining.

Critical timelines:

• First-calf heifers: If you do not see feet within one hour of the water bag appearing, or if no progress has been made in thirty minutes of active straining, it is time to investigate.
• Experienced cows: If you do not see feet within one hour, or if the cow has been actively straining for one hour with no progress, investigate.
• The universal rule: If the calf's head is visible at the vulva and the cow has been pushing for thirty minutes without delivering the shoulders, she needs help. That calf's umbilical cord is being compressed and it is running out of oxygen.

Stage 3: Placental Expulsion (2 to 8 Hours)

The placenta (afterbirth) should pass within two to eight hours after calf delivery. If the placenta has not passed within twelve hours, it is considered retained and will need veterinary attention. Do not pull on a retained placenta — you can cause uterine hemorrhage or prolapse. Leave it alone and call your vet.

Normal Presentation: What You Want to See

The normal presentation for a calf is anterior longitudinal, dorso-sacral — which in plain English means the calf is coming headfirst, right-side up, with both front legs extended forward. When you look at the vulva during Stage 2, you should see:

• Two front feet with the soles facing down (toward the ground). If the soles are facing up, the calf is either upside down or coming backward — both are problems.
• The nose resting on top of the front legs, about level with the knees.
• The head and feet should be passing through the vulva together, with the head fitting snugly between the two legs.

If this is what you see, the calving is probably going to go normally. You may still need to provide assistance if the calf is large relative to the cow's pelvis, but the presentation is correct.

Malpresentations: When Things Go Wrong

One Leg Back

You see one foot and the head, but the other leg is retained, folded back at the shoulder or elbow. This is the most common malpresentation and the one most producers can correct themselves. Wash up, lube up (OB lubricant — and use far more than you think you need), push the calf back slightly to create room, reach in alongside the calf's body, find the retained leg, cup the hoof in your hand (to protect the uterine wall from being torn by the sharp hoof), and bring it forward. Once both legs are forward, delivery can usually proceed.

Head Back

You see two feet at the vulva but no head — the head is turned back along the calf's body (to the left, right, or downward). This is more difficult to correct than a retained leg because you need to push the calf back far enough to create room to bring the head forward. Reach in, follow the neck to the head, place your hand around the lower jaw or in the eye sockets (I know, but you need the grip), and rotate the head forward while simultaneously pushing the body back. If the calf is large or the cow is straining hard against you, you may not be able to do this alone. This is a reasonable situation to call for help if your first attempt does not succeed within ten to fifteen minutes.

Breech Presentation

The calf is coming backward, butt-first, with both rear legs tucked forward under the body. You see nothing at the vulva — no feet, no head — but the cow is straining hard. On rectal or vaginal exam, you feel the calf's tail and buttocks. This is a veterinary call. Correcting a breech requires reaching in, pushing the calf forward, and individually extending each rear leg — all while working against the cow's contractions in a very tight space. It is possible for an experienced producer to correct, but if you have not done it before, call your vet.

Posterior Presentation (Backwards)

The calf is coming backward with both rear legs extended — you see two feet at the vulva with the soles facing up (toward the cow's tail). This is not a breech — the legs are extended, which is good — but delivery needs to be fast. Once the calf's hips enter the birth canal, the umbilical cord is compressed and the calf will begin trying to breathe. If the head is still inside the cow, the calf inhales amniotic fluid and drowns. You have approximately three to five minutes from the time the hips enter the canal to the time you need that calf's head clear and breathing. Pull steadily and do not stop once you start. This is a time-critical situation.

Hip Lock

The calf's head and shoulders have delivered, but the hips are hung up on the cow's pelvis. The calf is partway out, the cow is straining, and nothing is moving. Rotate the calf forty-five degrees (so the calf's hips are at an angle to the cow's pelvis rather than aligned with it) and apply steady traction. The rotated hips will often pass through the pelvis where the aligned hips would not. If rotation and traction do not free the hips within five minutes, you need a vet — the calf's oxygen supply is compromised and a caesarean section may be necessary.

Uterine Torsion

The uterus has twisted on its long axis, sealing the cervix and trapping the calf inside. The cow is in Stage 1 labor but never progresses — she is restless, uncomfortable, and not dilating. On vaginal exam, you will feel the cervix spiraled in a corkscrew pattern rather than open. This is a veterinary emergency. Correction involves rolling the cow (plank-in-the-flank method or manual detorsion under sedation) and almost always requires a veterinarian.

When YOU Can Pull

You can safely pull a calf yourself when all of the following conditions are met:

• The calf is in normal presentation (two front feet, soles down, head between the legs) or you have successfully corrected a simple malpresentation (one leg back).
• The cervix is fully dilated — you can fit your hand past the cervix without meeting resistance.
• The calf is alive (you can feel a suckle reflex when you put your finger in the calf's mouth, or the calf pulls its foot away when you pinch between the toes).
• The calf is a reasonable size relative to the cow — if the head barely fits through the vulva, the rest of the calf may not fit through the pelvis.

Pulling Technique

Chains or Straps

Use OB chains or nylon calving straps — never rope, wire, or anything that can cut. Place one loop above the fetlock joint and a half-hitch below the fetlock on each front leg. This distributes the force over two points on each leg and reduces the risk of fracturing the leg. Attach the chains to a calf puller (mechanical calf jack) or hand-pull.

Alternating Traction

Do not pull both legs simultaneously with constant force. Pull one leg forward six to eight inches, then pull the other leg forward the same distance. This alternating motion "walks" the calf's shoulders through the pelvis one at a time rather than trying to force both shoulders through simultaneously. It mimics the natural delivery process and significantly reduces the risk of injury to both the calf and the cow.

The Downward Arc

Once the calf's head and shoulders have cleared the vulva, change the direction of pull. Instead of pulling straight back, arc downward toward the cow's hocks. This follows the natural curve of the birth canal and helps the calf's hips clear the pelvis. Many producers make the mistake of continuing to pull straight back, which jams the calf's hips against the cow's pelvis.

How Much Force Is Too Much

The general guideline is that two people pulling by hand is the maximum force appropriate for a normal delivery. A calf puller (mechanical jack) can generate far more force than two people and should be used with caution — if you are cranking hard on a calf jack and the calf is not moving, the problem is not insufficient force. The problem is malpresentation, insufficient dilation, or a calf that is too big to fit. Stop pulling and reassess.

When You NEED a Vet

Call your veterinarian immediately for any of the following situations:

• Malpresentation you cannot correct within fifteen minutes (head back, breech, transverse)
• Incomplete cervical dilation (cervix is not opening fully despite active labor)
• A swollen calf head (if the calf has been in the birth canal too long, the head swells and becomes wedged — this almost always requires a cesarean section)
• Uterine torsion
• Twins tangled together (you reach in and find six legs and two heads — sorting out which legs belong to which calf while they are tangled in a contracting uterus is a skill that takes experience)
• Dead, emphysematous calf (the calf has been dead long enough to start decomposing — gas-filled, crepitant tissue, foul smell — this requires a fetotomy or cesarean section)
• Cow is exhausted and no longer straining effectively

Post-Calving Care

The Calf

Clear mucus from the nose and mouth immediately. If the calf is not breathing, stimulate it by tickling the inside of the nostril with a piece of straw, rubbing the chest vigorously with a towel, or pouring cold water on its head (the cold shock stimulates the first breath). Get colostrum into the calf within two hours — this is not optional. Dip the navel in 7% tincture of iodine to prevent navel infections (navel ill, joint ill).

The Cow

Monitor for retained placenta (should pass within eight to twelve hours). Watch for metritis (uterine infection) — signs include foul-smelling discharge, fever, depression, and decreased appetite in the days following calving. If the delivery was assisted, especially if you went in manually, the cow is at higher risk for metritis and should be monitored closely for seven to ten days. Any cow that required significant assistance (malpresentation correction, calf jack, veterinary intervention) should receive a post-calving exam from your vet within twenty-four to forty-eight hours.

The Bottom Line

Calving intervention is about timing and judgment, not heroics. Learn the normal stages and timelines so you recognize when something is wrong. Investigate early — a quick check is better than a late discovery. Correct simple problems yourself if you have the skill and the presentation allows it. Call your vet without hesitation when the situation exceeds your ability or experience, because a live calf and a healthy cow are always worth the farm call. The best calving season is the one where you never have to use your OB chains, but the second best is the one where you use them correctly.
