Health Records for Calves

A calf record starts the day the calf hits the ground. A few lines written at birth and a few more at each handling make it far easier to understand why some calves thrive and others struggle.

Start the record at birth

The calving pasture is where the best data is collected, and it is also where most records get skipped because everyone is tired. Make it easy: keep a notebook or waterproof card in the truck or the barn and fill it in before you leave the calf.

Tie the calf to its dam right away. Many health questions later in life, such as which cows consistently raise calves that need help, can only be answered if the calf is linked to the right cow.

• Calf ID and ear tag number, plus dam ID
• Birth date, sex and sire if known
• Calving ease: unassisted, easy pull, hard pull, or veterinary assistance
• Whether the calf stood and nursed, and about how long that took
• Birth weight if you have a scale
• Any visible problems such as weak suck, cold ears, a swollen navel or leg issues

Colostrum and the first hours

Record whether you saw the calf nurse and roughly when. If you had to assist, feed or tube a calf, note it, because that calf deserves extra attention over the next few weeks.

If your veterinarian offers a blood test for passive transfer of antibody, write down the result with the calf's ID. A calf that did not get enough colostrum is more likely to get sick, and the record helps you decide how closely to watch it.

Recording illness without guessing

When a calf looks off, write down what you actually saw rather than a diagnosis. Dull eyes, slow to rise, drooping ears, loose manure, cough, nasal discharge, hot swollen joint or a hollow flank are all useful details. Add the date, the weather and which pen or pasture the calf was in.

Record the vet's diagnosis once there is one, along with any instructions. Over time you will see whether calves from one pasture or one calving period tend to get the same trouble. That pattern is something your vet can work with.

Treatments, vaccines and withdrawal

Every vaccine or health product needs a date, the product name from the label, how it was given, who gave it and the lot number if you can read it off the bottle. Keep the vaccination schedule your veterinarian recommends for your herd and tick it off as you go.

For any treated calf, write the meat withdrawal date at once. Follow the label or the veterinarian's written instructions exactly, and mark the calf so it is not sold early. Residue avoidance is part of protecting the beef supply, and your records are your proof.

Weights, weaning and what buyers want to see

Weigh calves at weaning if you can, and record the weigh date so a 205-day adjusted weaning weight can be calculated. These numbers help you compare cow families and make better replacement choices.

If you sell calves, ask your buyer what they want documented. Some programs ask for vaccination dates, weaning dates and tag numbers. Programs differ, so ask the buyer or the program directly instead of assuming.

Keeping the record useful through the year

Set aside a few minutes after every working day to move notes from the chute sheet into the permanent file. Check that every calf on the sheet has a dam, a date and a result for anything that was done. Small gaps are easy to fix the same week and almost impossible to fix a year later.

At weaning, look back through the file for calves that were sick or treated. Ask yourself whether they share a dam, a sire, a pasture or a calving week. That review is where records start paying for themselves, and your veterinarian can help you read what the pattern might mean.

Common mistakes and what to ask

Frequent mistakes include writing records days later, losing tags and not knowing which calf is which, and recording only the calves that died. Another is mixing up twins or fostered calves with the wrong dam.

Ask your vet which calf records are most helpful at your next visit, whether a passive transfer test fits your herd and what to record during a scours or pneumonia outbreak.

• Back up tag IDs with a second form of identification
• Record fostered or twin calves clearly
• Write down recoveries, not just losses
• Enter data the same day
