Calving Difficulty: When to Assist

Most cows calve on their own. Knowing the signs that something is wrong, and calling for help early, saves calves and cows.

Key points

Most births need no help, but lack of progress means act.
Post your vet's number and an after-hours number before calving.
Call early and avoid pulling without training.
Record every assisted birth and use it in culling decisions.

What normal calving looks like

Calving has stages. First, the cow becomes restless and may separate from the herd as labor begins. Then the water bag appears and the calf is pushed out, followed by the placenta some hours later. Gestation is roughly nine months, about 283 days, but individual cows vary.

Watching without interfering is the right call for most births. Cows often do best when left alone, with a quiet check from a distance.

Learning to read your own herd helps here. Some cows calve quickly with little fuss, and others take longer without trouble. Record what is normal for each cow so you can tell when she is behaving differently.

Signs that something is wrong

Trouble shows up as lack of progress. A cow that has strained hard without producing a calf, a calf that is only partly out, a calf that is not positioned normally or a cow that is exhausted and giving up all need attention.

Ask your veterinarian in advance what timing you should use as a guide for your herd, because standards vary by cow, heifer and situation. Write the guidance on a card and keep it where everyone can see it.

Heifers calving for the first time tend to need closer watch. Check them more often and plan to have a helper nearby, particularly if they are young or small.

Hard straining with no progress
Only one foot or an unusual part showing
Calf's tongue swollen or calf not moving
Cow down, exhausted or bleeding
Cow stops trying and lies flat
Any time you are unsure

Preparing before calving season

Have a plan in place before the first cow calves. Post your veterinarian's phone number and after-hours number. Make sure you have a working headgate or calving pen, good lighting, clean water and clean equipment.

Ask your vet to teach you what you can and cannot do. Many ranchers take a hands-on calving clinic from a vet or extension office, which is much better than learning in the dark with a cow in trouble.

When to call the veterinarian

Call early. A vet who is called sooner has more options, and a calf delivered before it is exhausted has a better chance. If you have reached a point where you are not sure, that is the time to call.

Never use force beyond what you were taught, and never use mechanical aids without training. Wrong pulling can injure the calf, the cow and you.

If you have to leave the cow and wait for the vet, keep her quiet and calm, keep other cattle away and keep the area clear. Rushing around often makes the situation worse.

Safety for people and cattle

A calving cow is protective, and a cow in pain can be dangerous. Work with a helper, have a gate or panel between you and the cow when possible and keep an escape route open. Heifers can also be unpredictable.

Follow extension and OSHA guidance on handling and on working with a headgate or chute. Keep your clothes, hands and tools clean, and wash up afterward, since calving fluids can carry germs that affect people.

After the birth

Make sure the calf stands and nurses, and that the cow shows normal behavior. Calves from hard births are often weak and slow to nurse, so watch them closely. Ask your vet about colostrum and what to do if the calf does not nurse.

Record the calving ease, any help provided and the dam and calf IDs. Cows that need help repeatedly may be candidates for culling.

Heifers and cows that needed help should be rechecked the next day for general health, udder fill and any discharge that seems unusual, and your vet can advise on what to watch for.

Common mistakes and what to ask

The most common mistakes are waiting too long to call, intervening too early, pulling without training and leaving records blank. Another is failing to check heifers often enough.

Ask your vet when to step in, how to practice safe assistance, and which cows to cull for calving trouble.

Calling the vet too late
Pulling without training
Not watching heifers
No record of assisted births

When to get help: Ask your veterinarian for written guidance on when to step in and when to call, and consider a calving clinic. Call early whenever a birth is not progressing or you are unsure.
