Calving Management for Beef Herds: Preparation and Assistance

By Dr. Zubair Khalid, DVM, MS, PhD · 2026-08-14

Key Takeaways

• Target a Body Condition Score (BCS) of 5-6 for mature cows and 6 for first-calf heifers at calving to optimize rebreeding success and minimize calving complications; BCS below 5 increases postpartum intervals and reduces conception rates, while BCS above 7 elevates dystocia risk and metabolic disease incidence.
• Proactive pre-calving preparation is critical, including assembling a complete calving kit at least two weeks prior, ensuring adequate nutrition to meet increased energy demands in the last trimester, and implementing appropriate vaccination protocols 3-6 weeks before calving to boost colostral antibody transfer.
• Recognize the three stages of labor: Stage 1 (2-6 hours) involves cervical dilation and calf rotation, Stage 2 (30-60 minutes for cows, up to 2 hours for heifers) is active straining and delivery, and Stage 3 (2-8 hours) is placental expulsion; intervention is warranted if Stage 2 exceeds 2 hours of active straining or 30 minutes of hard straining with no progress.
• Ensure immediate post-calving calf care, prioritizing navel disinfection with 7% iodine solution and ensuring colostrum intake within 2-4 hours of birth to provide essential antibodies, as calf's ability to absorb colostral immunoglobulins declines rapidly after birth.
• Implement rigorous recordkeeping, tracking birth date, birth weight, calving ease scores, assistance provided, and any observed problems, to facilitate genetic evaluation, identify problem cows for culling, and refine future calving management strategies.
• Promptly address dystocia, defined as difficult birth, by identifying fetal malpresentations (e.g., head back, breech) or oversize, and seek veterinary assistance if progress is not made within 20-30 minutes of gentle traction or if the cow exhibits signs of distress.

Calving season is the most critical period in the beef cattle production calendar. The decisions you make in the weeks before birth and the actions you take during delivery directly affect calf survival, cow health, rebreeding success, and your operation's bottom line. This guide is written for beef cattle producers, ranch managers, and farm workers who want a practical, step-by-step approach to calving management. It covers pre-calving preparation, the stages of normal labor, when and how to assist, calf care after birth, common problems, and recordkeeping systems that improve your results over time.

At a Glance

Understanding Normal Calving: The Three Stages

Calving management begins with knowing what normal looks like. Cows and heifers progress through three distinct stages of labor. Each stage has recognizable signs, and knowing where an animal is in the process tells you when to wait and when to act.

Stage One: Preparation and Dilation

Stage one begins with the onset of uterine contractions and ends with full cervical dilation. This stage typically lasts 2 to 6 hours, though it can be shorter in mature cows and longer in first-calf heifers.

Signs of stage one are subtle but observable with regular checking:

• The cow isolates herself from the herd
• She appears restless, gets up and lies down repeatedly
• She switches her tail or holds it raised
• She may urinate frequently in small amounts
• The vulva appears swollen and relaxed
• A thick mucus discharge may be visible
• She may reduce feed intake or stop eating entirely

During stage one, the cervix relaxes and dilates. The calf rotates from a lying position into the normal birthing position with front feet and head extended toward the birth canal. Uterine contractions gradually increase in frequency and intensity.

Do not interfere during stage one. Internal examination during this phase can introduce bacteria and cause unnecessary stress. The cow needs quiet and space. Moving her or forcing her into a chute at this stage can stall labor.

Stage Two: Active Delivery

Stage two begins when the calf enters the birth canal and ends with delivery. This is the stage where visible abdominal straining begins. The cow will lie on her side, strain forcefully, and make steady progress.

Normal duration for stage two:

• Mature cows: 30 to 60 minutes
• First-calf heifers: up to 2 hours

During stage two, you should observe the cow from a distance. Do not enter the pen unless you have a reason. Watch for the appearance of the water bag, then the calf's feet and head.

Normal presentation at delivery:

• Both front feet appear first, one slightly ahead of the other
• The nose rests between the two front legs at the level of the knees
• The calf's head and feet are visible together
• The soles of the feet point downward

The cow should make steady progress. If she strains hard for 30 minutes with no visible progress, or if 2 hours pass without delivery from the start of active straining, intervention is needed.

Stage Three: Placental Expulsion

Stage three is the delivery of the fetal membranes, commonly called the afterbirth. This usually occurs within 2 to 8 hours after the calf is born. The placenta may hang from the vulva for up to 12 hours.

Do not pull on the placenta. Forcing placental removal can cause uterine damage, bleeding, and infection. Most cows pass the placenta naturally within 12 hours. If the placenta is retained beyond 24 hours, consult your veterinarian.

Pre-Calving Preparation

The work you do in the weeks before calving starts determines how smoothly the season runs. Preparation involves three areas: cow condition and nutrition, facilities and equipment, and personnel and protocols.

Body Condition Scoring and Nutrition

Body condition score at calving is the single most important factor influencing calving difficulty and rebreeding success. The scale runs from 1 (emaciated) to 9 (obese). Target a body condition score of 5 to 6 for mature cows and 6 for first-calf heifers at calving.

A body condition score of 5 means the cow has a moderately conditioned frame. You can feel her ribs with light pressure, but they are not prominent. The brisket and tailhead are full. A score of 6 means the ribs are covered with fat and require firm pressure to feel. The brisket is spongy and the tailhead is rounded.

Cows that calve at a body condition score below 5 have:

• Longer postpartum intervals before rebreeding
• Lower conception rates
• Weaker calves at birth
• Reduced colostrum quality
• Higher risk of calving complications

Cows that calve at a body condition score above 7 have:

• Increased calving difficulty from fat deposition in the birth canal
• Higher rates of retained placenta
• Greater risk of metabolic disease
• Reduced feed intake after calving

Manage body condition through the fall and early winter. The most efficient time to add condition is during the last trimester when the cow's energy requirements increase. A cow needs roughly 10 to 15 percent more energy in the last 60 days of gestation than in mid-gestation.

Work with your feed supplier or extension agent to test hay and forage quality. A simple forage test tells you the protein and energy content of your feed, which lets you balance rations accurately. Do not guess when you can measure.

Vaccination and Health Programs

Vaccination timing around calving serves two purposes. First, it protects the cow from diseases that can cause abortion or illness. Second, it boosts antibody levels in colostrum to protect the newborn calf.

A standard pre-calving vaccination program includes:

• Scours vaccines (rotavirus, coronavirus, E. coli, clostridial types) given 3 to 6 weeks before calving
• Clostridial vaccines (blackleg, malignant edema) if not given earlier in the year
• IBR, BVD, PI3, and BRSV vaccines for respiratory protection
• Leptospirosis and vibriosis vaccines in areas where these diseases are present

Give vaccines at the recommended time before calving. Vaccinating too early or too late reduces colostral antibody transfer to the calf. Follow the label directions and your veterinarian's recommendations for your specific region.

Do not vaccinate cows in the last 2 weeks before calving unless your veterinarian specifically recommends it. The stress of handling and injection can trigger early labor in some animals.

Calving Area and Facilities

A clean, dry, well-drained calving area reduces calf scours and other diseases. The ideal calving area provides:

• A grassy or well-drained area that stays dry in wet weather
• Protection from wind and extreme weather
• Good drainage away from the resting area
• Access to clean water and feed
• Easy observation from a vehicle or walking path

For intensive calving operations, consider a calving barn or shed with individual pens. Each pen should be at least 12 by 12 feet and provide:

• Deep, clean straw bedding
• Good ventilation without drafts
• Easy access for the producer and veterinarian
• A way to restrain the cow for examination or assistance

If you use a calving barn, clean and disinfect it thoroughly before the season starts. Remove all old bedding, scrub walls and floors with a disinfectant solution, and allow the facility to dry completely before adding fresh bedding. Disease organisms from previous seasons can survive in cracks and crevices.

The Calving Supplies List

Assemble your calving kit at least 2 weeks before the first due date. Store it in a clean, portable container that you can carry to the calving area. Check and restock the kit every week during calving season.

Essential supplies for your calving kit:

• Obstetrical gloves (long-sleeved, disposable)
• Obstetrical lubricant (water-soluble, non-spermicidal)
• Two clean obstetrical chains with handles
• Two obstetrical straps (nylon or cotton)
• A calf puller (obstetrical jack) in good working condition
• A flashlight with extra batteries
• Paper towels and clean rags
• Disinfectant solution (chlorhexidine or povidone-iodine)
• 7 percent iodine solution for navel treatment
• Scissors or a sharp knife
• A bulb syringe for clearing the calf's airways
• A stethoscope
• A digital thermometer
• Colostrum replacer or colostrum from a known healthy cow
• An esophageal feeder for administering colostrum
• Ear tags and tagging applicator
• A notebook and pen for records
• A cell phone or two-way radio for calling for help

Check your calf puller before calving season. Clean it, oil the moving parts, and test it on a secure post. A broken calf puller in the middle of a difficult delivery is a serious problem.

Personnel and Communication

Decide in advance who will be responsible for calving checks. Write out the schedule and post it where everyone can see it. In a family operation, this might mean rotating night checks. In a larger operation, assign specific shifts.

Every person involved in calving should know:

• How to recognize the stages of labor
• When to call for help
• The phone numbers for the veterinarian and experienced neighbors
• The location of the calving kit
• The calving protocols for your operation

Hold a pre-calving meeting to review protocols. Walk through the calving area, demonstrate equipment use, and discuss what to do in common emergencies. This 30-minute investment saves hours of confusion later.

When to Assist Calving

Knowing when to intervene is the most important judgment you make during calving season. Intervening too early can cause injury to the cow and calf. Waiting too long can cost the calf its life and put the cow at risk.

General Guidelines for Intervention

Call for veterinary assistance or begin examination when:

• Stage one lasts longer than 8 hours without progressing to stage two
• The cow strains hard for 30 minutes with no visible progress
• The cow has been in active labor for more than 2 hours without delivery
• The water bag appears but no feet or head follow within 30 minutes
• Only one foot appears and no head is visible
• The feet appear but the head is not between them
• The feet appear with soles facing upward
• The calf's head appears but the feet are not extended
• You see abnormal discharge such as dark green or bloody fluid
• The cow shows signs of distress such as rapid breathing or extreme agitation

If you are uncertain whether to intervene, examine the cow. A clean, gentle vaginal examination tells you the position of the calf and the progress of dilation. If you are not experienced with internal examination, call your veterinarian.

The 2-Hour Rule

The 2-hour rule is a simple guideline that saves calves and cows. If a cow has been actively straining for 2 hours without delivering the calf, she needs help. For heifers, use a 1-hour rule because heifers tire faster and have narrower birth canals.

Active straining means visible abdominal contractions that push the calf toward the birth canal. Occasional mild contractions are normal. Continuous hard straining with no progress is a red flag.

Assessing the Situation

When you decide to examine a cow, follow these steps:

1. Restrain the cow safely in a chute or head catch. Do not work a cow in an open pen if you can avoid it.
2. Clean the area around the vulva with mild soap and water. Dry it thoroughly.
3. Put on clean obstetrical gloves and apply lubricant.
4. Insert your hand gently into the vagina. Note the degree of dilation.
5. Identify the calf's parts. You should feel two front feet and a head, or two back feet and a tail.
6. Assess the size of the calf relative to the birth canal.
7. Determine if the calf is alive by checking for a suckle reflex, eye movement, or pulse in the umbilical cord.

Record your findings. If the calf is in normal position and the birth canal is adequately dilated, you may assist with gentle traction. If the calf is malpositioned or too large, call your veterinarian.

How to Assist a Normal Delivery

When the calf is in normal position and the birth canal is dilated, you can assist with gentle traction. The goal is to help the cow deliver quickly without causing injury.

Step-by-Step Assisted Delivery

1. Restrain the cow in a chute or head catch. If she is lying down and making progress, you can work with her on the ground, but a chute is safer for both of you.
2. Clean the vulva and surrounding area with mild soap and water.
3. Put on clean gloves and apply obstetrical lubricant to your hand and arm.
4. Confirm the calf is in normal position. You should feel two front feet and the head between them.
5. Attach obstetrical chains to the calf's legs above the fetlock joint. Use a half-hitch knot that will not slip.
6. Apply traction only during the cow's contractions. Pull when she strains, rest when she rests.
7. Pull downward and backward at an angle that follows the natural curve of the birth canal. For a standing cow, pull downward and slightly back. For a lying cow, pull straight back.
8. Pull gently and steadily. Two people pulling together is usually sufficient. Do not use excessive force.
9. As the calf's head emerges, slow down. Allow the cow to rest between contractions.
10. When the shoulders enter the birth canal, rotate the calf slightly to allow the shoulders to pass one at a time.
11. Once the shoulders are through, the rest of the calf delivers quickly. Support the calf as it emerges to prevent it from falling hard to the ground.

Never pull with all your strength. If the calf does not move with reasonable traction, stop and call your veterinarian. Excessive force can cause nerve damage to the cow, fractures in the calf, and uterine rupture.

Using a Calf Puller

A calf puller is a mechanical device that provides steady, controlled traction. It is useful for deliveries that need more pulling force than two people can provide by hand. However, a calf puller can cause serious injury if used incorrectly.

Use a calf puller only when:

• The cervix is fully dilated
• The calf is in normal position
• The birth canal is adequately lubricated
• You have confirmed the calf is alive and the cow is healthy

To use a calf puller:

1. Attach the chains to the calf's legs as described above.
2. Position the calf puller according to the manufacturer's instructions.
3. Apply traction slowly and steadily during contractions.
4. Stop pulling when the calf's head emerges.
5. Rotate the calf if needed to deliver the shoulders.
6. Remove the calf puller as soon as the shoulders are delivered.

Check the calf puller's condition before each use. Clean and disinfect it between animals. A dirty calf puller can spread disease from one cow to the next.

Common Mistakes During Assisted Delivery

The most common mistakes producers make during assisted delivery include:

• Pulling too early before the cervix is fully dilated
• Pulling too hard and causing injury to the cow or calf
• Failing to lubricate the birth canal adequately
• Not identifying a malpositioned calf before pulling
• Pulling when the calf is too large for the birth canal
• Continuing to pull after the calf should have been delivered by cesarean section

If you are not making progress after 20 to 30 minutes of gentle traction, stop and call your veterinarian. Continuing to pull increases the risk of injury and reduces the chance of saving the calf.

Malpresentations and Dystocia

Dystocia means difficult birth. It is the leading cause of calf death at birth and a major cause of cow mortality and reduced fertility. Understanding the common malpresentations helps you recognize problems early and respond appropriately.

Causes of Dystocia

The most common causes of dystocia in beef cattle:

• Fetal malpresentation (abnormal position of the calf)
• Fetal oversize (the calf is too large for the birth canal)
• Incomplete cervical dilation
• Uterine inertia (weak or absent contractions)
• Twinning
• Abnormal fetal development
• Maternal factors such as a narrow pelvis, especially in first-calf heifers

Sire selection has a major influence on calving difficulty. Using calving-ease bulls on heifers reduces the risk of fetal oversize. The birth weight of the calf is the single most important calf factor affecting calving difficulty.

Common Malpresentations

The calf can present in several abnormal positions. Each requires a specific correction before delivery can proceed.

Head back: The calf's front feet are extended but the head is turned back along the side of the body. This is one of the most common malpresentations. To correct it, push the calf back into the uterus, cup your hand around the calf's muzzle, and gently guide the head forward between the front legs.

Breech presentation: The calf's hind legs are extended toward the uterus instead of the birth canal. The tail and buttocks present first. This is a serious malpresentation that requires veterinary assistance. The calf must be pushed back and the hind legs brought forward into the birth canal.

One leg back: One front leg is extended normally but the other is folded back. To correct this, push the calf back slightly, cup the folded leg at the hoof and knee, and bring it forward into the birth canal.

Backward presentation: The calf presents hind feet first with the tail visible. This is a normal presentation for about 5 percent of calves. Delivery in this position requires rapid assistance because the umbilical cord is compressed during delivery, cutting off oxygen to the calf.

Upside down: The calf presents with the soles of the feet facing upward instead of downward. This indicates the calf is rotated. The calf must be rotated to the correct position before delivery.

When to Call the Veterinarian for Dystocia

Call your veterinarian immediately when:

• You cannot identify the calf's position
• The calf is in a breech or other serious malpresentation
• The cervix is not fully dilated after 8 hours of stage one
• You have pulled for 20 to 30 minutes without progress
• The calf is very large and the birth canal is small
• The cow shows signs of shock or severe distress
• You suspect a uterine tear or rupture
• You are not experienced with the correction needed

Do not delay the call. Every hour of delay reduces the chance of saving the calf and increases the risk to the cow. A veterinarian can perform a cesarean section or other procedures that you cannot do on the farm.

Calf Care After Birth

The first hours after birth determine the calf's health and survival. Your actions during this period have a direct impact on the calf's ability to stand, nurse, and thrive.

Immediate Calf Care

When the calf is born:

1. Clear the calf's nose and mouth of mucus and fetal fluid. Use a bulb syringe or your fingers wrapped in a clean cloth.
2. Stimulate the calf to breathe. Rub the chest and sides vigorously with a clean towel or straw. This stimulates breathing and circulation.
3. Check the calf's breathing and heart rate. A healthy calf breathes within 30 seconds of birth and lifts its head within 2 to 3 minutes.
4. Allow the cow to lick the calf. This dries the calf, stimulates bonding, and releases oxytocin in the cow, which helps expel the placenta.
5. Treat the navel with 7 percent iodine solution. Dip the entire navel cord in the solution to disinfect it. Repeat the treatment 2 to 4 hours later.
6. Make sure the calf nurses within 2 to 4 hours of birth. Colostrum provides antibodies that protect the calf from disease.

Colostrum Management

Colostrum is the first milk, and it is loaded with antibodies, nutrients, and growth factors. The calf is born with no immunity of its own. It relies entirely on antibodies absorbed from colostrum through the intestinal wall.

The calf's ability to absorb colostral antibodies decreases rapidly after birth. Maximum absorption occurs in the first 6 hours. By 24 hours, the intestinal wall no longer allows antibody absorption.

Guidelines for colostrum:

• The calf should receive colostrum within 2 to 4 hours of birth
• Aim for at least 5 to 10 percent of the calf's body weight in colostrum within the first 12 hours
• A 90-pound calf needs about 4.5 to 9 pounds of colostrum in the first 12 hours
• Use colostrum from the calf's own dam whenever possible
• If the dam has no colostrum, use colostrum from a healthy cow in your herd or a commercial colostrum replacer
• Colostrum quality varies. Cows that calve early, first-calf heifers, and cows with mastitis produce lower quality colostrum

If the calf does not nurse within 4 hours, assist it. Milk the cow and tube-feed the colostrum to the calf or guide the calf to the teat. A weak calf needs help to stand and find the teat.

Checking the Calf for Problems

Examine every calf after birth for:

• Cleft palate or other facial abnormalities
• Limb deformities or fractures
• Hernias at the navel
• Signs of weakness or respiratory distress
• Proper nursing behavior

A healthy calf should stand within 30 to 60 minutes of birth and nurse within 2 to 4 hours. If the calf has not nursed by 6 hours, intervene.

Post-Calving Cow Care

The cow's care after calving affects her health, milk production, and ability to rebreed. Attention to the cow in the first days after calving prevents common problems.

Immediate Cow Care

After the calf is delivered:

1. Give the cow clean, fresh water. She may be dehydrated after labor.
2. Provide high-quality hay or pasture. Her energy requirements increase sharply with lactation.
3. Observe for placental expulsion. The placenta should pass within 12 hours.
4. Check for signs of excessive bleeding or discharge.
5. Monitor her temperature for the first 3 days. A temperature above 103 degrees Fahrenheit may indicate infection.
6. Allow the cow and calf to bond without interference.

Common Post-Calving Problems

Retained placenta: If the placenta is not expelled within 12 to 24 hours, it is considered retained. Do not pull on the placenta. Most cows pass the placenta within 3 to 5 days. Consult your veterinarian if the cow develops a fever, goes off feed, or shows signs of illness.

Metritis: This is an infection of the uterus, usually occurring in the first 10 days after calving. Signs include fever, reduced appetite, foul-smelling discharge, and decreased milk production. Metritis requires veterinary treatment with antibiotics and supportive care.

Mastitis: Udder infection can occur after calving. Signs include a swollen, hot, painful udder and abnormal milk. Treat mastitis promptly to prevent damage to the udder and loss of milk production.

Milk fever: This condition, also called hypocalcemia, occurs when blood calcium levels drop too low. It is more common in older cows and high-producing dairy breeds, but it can occur in beef cows. Signs include weakness, tremors, and recumbency. Treatment requires intravenous calcium administered by a veterinarian.

Downer cow syndrome: A cow that cannot stand after calving has a poor prognosis. Causes include nerve damage from difficult birth, metabolic problems, and injuries. Call your veterinarian immediately for a downer cow.

Monitoring and Recordkeeping

Systematic monitoring and accurate records improve your calving management year after year. Records help you identify problem cows, evaluate bull performance, and make better culling and breeding decisions.

Calving Checks

During peak calving season, check cows every 4 to 6 hours around the clock. For first-calf heifers, check every 2 hours. Heifers are more likely to need assistance and have less experience with labor.

When checking cows:

• Count all cows and calves to ensure every cow has her calf
• Watch for cows in active labor
• Look for signs of abnormal discharge or distress
• Check that newborn calves are nursing
• Observe cow behavior for signs of illness

Use a flashlight at night. Cows often calve during the night, and a good flashlight lets you see what is happening without disturbing the herd.

What to Record

Record the following for every calving:

• Cow identification (ear tag number or name)
• Calf identification
• Date and time of birth
• Birth weight
• Sex of the calf
• Calving ease score (1 equals unassisted, 2 equals easy pull, 3 equals hard pull, 4 equals cesarean, 5 equals malpresentation requiring correction)
• Any assistance given and by whom
• Any problems with the cow or calf
• Colostrum intake and timing
• Treatments given

Calving ease scores are valuable for genetic evaluation. If you use artificial insemination or participate in a breed association program, these scores contribute to expected progeny differences for calving ease.

Using Records to Improve

Review your calving records at the end of each season. Look for patterns:

• Which cows had difficulty calving? Consider culling repeat offenders.
• Which bulls produced calves with high birth weights? Use lower birth weight bulls on heifers.
• What time of day do most calves arrive? Adjust your check schedule accordingly.
• What problems occurred most often? Focus your prevention efforts on those areas.

Records also help you identify cows with good maternal traits. Cows that calve easily, have strong calves, and rebreed quickly are your most valuable animals.

Common Mistakes in Calving Management

Even experienced producers make mistakes during calving season. Reviewing the most common errors helps you avoid them.

Checking cows too infrequently: Cows can progress from stage one to delivery in a few hours. Infrequent checks mean you miss cows that need help. During peak calving, check every 4 hours or more often.

Interfering too early: Examining a cow before the cervix is fully dilated can introduce infection and slow labor. Wait for clear signs of stage two before you intervene.

Pulling too hard: Excessive force causes more calving injuries than any other factor. If the calf does not come with reasonable traction, get help.

Failing to lubricate: Dry, rough hands and chains cause friction and injury. Use generous amounts of obstetrical lubricant on your hand, the birth canal, and the calf's legs.

Neglecting the calf after birth: The minutes after birth are critical. Clear the airways, stimulate breathing, disinfect the navel, and ensure colostrum intake.

Ignoring the cow after calving: Watch the cow for retained placenta, metritis, mastitis, and other problems in the days after calving. Early treatment saves lives.

Poor sanitation: Dirty equipment, dirty hands, and dirty facilities spread disease. Clean and disinfect everything between animals.

Not having a plan: Calving emergencies happen at 2 a.m. in bad weather. Have a written plan, a stocked calving kit, and a veterinarian on call before the season starts.

When to Call a Veterinarian or Extension Agent

Knowing your limits is a sign of good management, not weakness. Call for professional help in the following situations:

Call a Veterinarian When

• The cow has been in active labor for more than 2 hours without progress
• You cannot identify the calf's position
• The calf is in a breech or other serious malpresentation
• You have pulled for 20 to 30 minutes without progress
• The cow shows signs of shock, severe distress, or exhaustion
• The cow cannot stand
• You suspect a uterine tear or rupture
• The cow has a retained placenta with fever or illness
• The cow has a vaginal or uterine prolapse
• The calf is very large and the birth canal is small
• You are not experienced with the correction needed

Have your veterinarian's phone number posted in the calving area and saved in your phone. Know the best route to the clinic and the emergency contact procedure.

Call an Extension Agent When

• You want help developing a nutrition program for pregnant cows
• You need assistance interpreting forage test results
• You want to evaluate your calving recordkeeping system
• You are selecting bulls and want information on calving ease expected progeny differences
• You want to learn more about calving management through workshops or publications
• You are planning facility improvements and want design guidance

Extension agents provide education and resources at no cost. They are connected to university research and can help you apply science-based practices to your operation.

Frequently Asked Questions

How often should I check cows during calving season?

Check cows every 4 to 6 hours during peak calving season. For first-calf heifers, check every 2 hours because they are more likely to need assistance. During the night, use a flashlight and observe quietly from a distance so you do not disturb cows that are in labor. The goal is to catch problems early without interfering with normal calving.

What is the normal length of labor in beef cows?

Stage one labor lasts 2 to 6 hours, during which the cervix dilates. Stage two, or active delivery, lasts 30 to 60 minutes in mature cows and up to 2 hours in first-calf heifers. If a cow has been straining hard for 30 minutes with no progress, or for 2 hours without delivering, she needs assistance.

How do I know if a calf is getting enough colostrum?

A calf should nurse within 2 to 4 hours of birth. You should see it suckling vigorously and appearing satisfied afterward. By 12 hours, the calf should be active and looking for the udder. If you are unsure whether the calf nursed, watch for a full belly and check that the cow's udder is being emptied. You can also test blood immunoglobulin levels 24 to 48 hours after birth, but this requires veterinary assistance.

Can I pull a calf that is presented backwards?

A backward presentation with both hind feet extended is a normal presentation for about 5 percent of calves, but it requires faster delivery because the umbilical cord is compressed during birth. You can assist with gentle traction, but the calf must be delivered quickly. If you are not experienced with backward deliveries, call your veterinarian.

What should I do if the placenta is retained?

Do not pull on the placenta. Most cows pass the placenta within 12 hours of calving. If the placenta is retained beyond 24 hours, monitor the cow for fever, reduced appetite, or foul-smelling discharge. Contact your veterinarian if the cow shows signs of illness. Do not attempt manual removal unless directed by your veterinarian.

How long after calving should a cow come into heat?

Most beef cows return to heat within 40 to 60 days after calving. The postpartum interval depends on body condition, nutrition, and whether the cow had calving difficulty. Cows that calve in good body condition and have no complications typically cycle sooner. First-calf heifers often take longer to resume cycling.

What birth weight causes calving difficulty in beef cattle?

Birth weight is the most important calf factor affecting calving difficulty. Calves weighing more than 90 to 95 pounds are at higher risk of causing dystocia, especially in first-calf heifers. However, birth weight alone does not predict calving difficulty. Pelvic size of the dam, calf position, and duration of labor also matter. Select bulls with low birth weight expected progeny differences for use on heifers.

How can I reduce calving problems in first-calf heifers?

Start with heifers that are adequately grown and developed before breeding. Target 60 to 65 percent of mature body weight at breeding. Use calving-ease bulls with low birth weight expected progeny differences. Keep heifers in good body condition during the last trimester. Provide a separate, well-bedded calving area for heifers and check them more frequently. Feed heifers separately from mature cows so they get adequate nutrition.
