Dehorning and Disbudding: Welfare and Best Practices

Horns can injure people and herd mates, which is why many dairies remove them. How and when this is done matters a great deal for the calf's welfare.

Why it is done, and why it is debated

Horned cattle can hurt handlers and other cows, damage equipment and cause problems in feed bunks and housing. For this reason many dairies remove horn buds from calves, and some breed polled genetics instead.

Opinions on the practice vary and rules differ by buyer, certification program and country. Your veterinarian and milk buyer can explain the expectations that apply to you.

Some buyers and programs set clear expectations on timing and pain control, so ask your milk buyer before you set your routine. Whatever your view, the shared aim is a calf that is handled gently, kept comfortable and cared for by trained people.

Disbudding versus dehorning

Disbudding is the removal of the horn bud in a young calf, before the horn is attached to the skull. Dehorning removes a horn that has already grown and is a larger and more painful procedure.

Doing the job early is generally gentler for the calf. Ask your vet about the best timing and method for your herd.

Because the horn bud is only loosely attached in a very young calf, early action allows a smaller procedure with less tissue damage, which is a main reason timing matters. Know the difference in your own records too, and note the age of every calf when the work is done.

Welfare comes first

Both procedures cause pain, and the pain can last after the work is done. Pain relief and restraint should be planned in advance with your veterinarian, who can tell you which methods and products are suitable and legal.

Pain relief products may carry withdrawal times, so keep records and follow label or vet instructions exactly. Ask your vet to be present for the first few procedures with new staff, so that technique and timing are checked in person rather than assumed.

• Plan pain relief with your vet before the procedure
• Use trained people and clean, working equipment
• Restrain the calf calmly and safely
• Watch for signs of pain afterward
• Keep records of every calf

Planning and technique

Choose a quiet time, and do not combine the procedure with other stressors such as weaning, moving or vaccination in the same week. Make sure the calf is healthy and the area is clean and dry.

Training matters. Anyone doing this work should be shown the method by your vet or an experienced professional, and follow the equipment manufacturer's safety directions. Burns and injuries to people are a risk with heated equipment.

Equipment should be kept clean and in good working order, and used only by someone who has been shown how. Never rush the job or work with animals that are not properly restrained.

Aftercare and monitoring

Check calves daily after the procedure. Look for bleeding, swelling, discharge, flies, poor appetite, head shaking or a calf standing apart. Keep the pen clean, dry and well bedded.

Call your vet if healing looks wrong or the calf seems to be in more pain than expected.

Do not forget the people. Wash hands and cover cuts after working with calves, and keep children away from the area during the procedure. Keep the calf's pen clean and dry for the first days, and keep other calves from sucking on or rubbing the sore area.

Alternatives and common mistakes

Polled genetics can reduce or remove the need for the procedure over time. Ask your breeding adviser or genetics provider what is available.

Common mistakes include waiting too long, skipping pain relief, poor restraint, untrained operators and missing aftercare. Review your protocol with your vet each year, and check certification program rules. Breeding decisions take time to pay off, so discuss a long-term plan with your genetics provider alongside your current routine.

Records, training and review

Keep a short record for each calf: the date, the method, who did it, the pain control used as your vet directed, and any follow-up. Review the records with your vet to spot calves that healed poorly.

Train new employees before they assist, and do not let anyone take on the procedure alone until your vet or an experienced professional is satisfied.

• Written protocol agreed with your vet
• Training sign-off for each person
• Record for every calf
• Annual review of the method and results
