If you’ve ever disbudded a goat kid and later noticed what looks like a tiny horn or a hard, twisted lump growing where the horn bud was, you’ve encountered one of the most frustrating side effects of the disbudding process: scurs.
Scurs in goats are a common — and preventable — issue that usually results from incomplete disbudding. While they’re often harmless, they can become a nuisance or even a hazard, especially in bucks. In this article, we’ll take a deep dive into what scurs are, why they develop, and how you can prevent them through more effective disbudding practices.

What Are Scurs?
Scurs are abnormal, partial regrowths of horn tissue that appear after a goat has been disbudded. Unlike full horns, scurs don’t typically fuse to the skull. Instead, they’re loosely attached to the skin and may appear as misshapen, twisted, or stunted horn fragments.
They’re usually small and may break off during normal goat activities like butting heads or rubbing against a tree, but in some cases, scurs can curl back toward the head or become large enough to cause injury.
How Are Scurs Different from Horns?
True horns are firmly anchored to the skull by a bony core and fed by a rich supply of blood vessels and nerves. They grow continuously and have a symmetrical, tapered shape covered by a keratin sheath.
Scurs, on the other hand:
- Are often irregular in shape and texture
- May grow at odd angles or twist
- Are usually not attached to the skull
- Tend to break off easily
Scurs are also unpredictable. Some goats may grow small scurs that never cause issues, while others develop large, sharp, or curly ones that require intervention.
What Causes Scurs in Goats?
Scurs are almost always caused by incomplete destruction of the horn bud during disbudding. If any horn-producing cells remain after the procedure, they can regenerate tissue — though the result is typically malformed.
1. Incomplete Horn Bud Destruction
This is the number one cause of scurs. If the disbudding iron does not burn deep enough or wide enough to destroy all of the horn-producing cells in and around the horn bud, those cells can regenerate and produce scurs.
2. Disbudding Too Late
Timing is critical. Disbudding after the horn bud has grown too large — or worse, has erupted through the skin — significantly reduces the effectiveness of the procedure. In goats older than 10–14 days (especially bucks), the bud has already started integrating with deeper tissues, making complete destruction much harder.
3. Skipping the Center Burn
One common mistake is burning only the ring around the horn bud without removing the cap and cauterizing the center. The core of the bud contains the highest concentration of horn progenitor cells. If this area isn’t ablated, scurs develop. In a study where the compared disbudding that burned the center vs disbudding that only burned a ring, 100% of the goats developed scurs when the center was not burned.
4. Bucks Are More Prone
Even when disbudding is performed correctly, buck kids have a higher rate of scur development due to the effects of testosterone. Hormonal stimulation enhances horn tissue growth and regeneration, making it harder to destroy all the necessary tissue with a single burn.
When and Where Scurs Appear
Scurs typically begin to appear several weeks after disbudding — once the healing process is complete. You might notice small, hard nubs, often in or near the original disbudding site.
Scurs most often form at:
- The front edge of the original horn bud site — especially in bucks
- The center of the site if the cap wasn’t removed
- Peripheral edges where the burn didn’t completely encircle the bud
Some goats grow only one scur, while others grow two — or none at all if disbudding was successful.
Can Scurs Be Prevented?
Yes — in most cases, scurs are preventable with good timing, effective technique, and special considerations for male kids.
Timing
Disbud early — ideally between 3 and 7 days of age for Nigerian Dwarfs and 5 to 10 days for larger breeds. Buck kids usually need to be done on the earlier end of that window because their horn buds develop faster.
Waiting beyond two weeks greatly increases the chances of scur formation.
Technique
To reduce the risk of scurs:
- Use a properly heated disbudding iron with a 1/2-inch tip for goats of all sizes, even Nigerian dwarf
- Clip the hair for better visibility
- Burn until a complete copper ring forms around the bud
- Remove the horn bud cap and burn the exposed center
Special Step for Bucks
In addition to the standard technique, buck kids benefit from a second half-ring burn just in front of the main burn. This targets a zone of extra horn-producing tissue that bucks have.
What to Do If a Goat Has Scurs
Not all scurs require intervention, but some can lead to injuries or health problems.
Trim if Needed
If the scur grows long or sharp, you can trim it with hoof trimmers or a wire saw, such as a coping saw. Be cautious — while scurs aren’t fully fused to the skull, they may still bleed or cause discomfort if cut too close to the base.
Monitor for Problems
Watch for scurs that:
- Curl around and grow inward toward the skull, which can ultimately result in death if the scur doesn’t break off
- Cause sores or infections
- Bleed frequently or snag on fencing
In these cases, removal may be necessary. However, surgical scur removal is invasive and often requires sedation. It’s best reserved for severe or persistent issues and done by a veterinarian.
Expect Recurrence
Even if you trim or remove a scur, it may grow back. This is because the underlying tissue wasn’t completely destroyed. If you have repeated issues with scurs, it may be worth reviewing your disbudding protocol for future kids.
Does Genetics Play a Role?
While genetics can influence horn growth patterns, scurs are primarily the result of disbudding technique — not inherited traits. However, polled goats (those born naturally without horn buds) can carry a gene for intersex conditions when bred together, so routine disbudding is still a preferred management practice for most breeders who want goats without horns.
Final Thoughts
Scurs are frustrating but largely preventable. If you’ve struggled with scurs in your herd, reviewing your disbudding method and timing can make a big difference.
Here’s a quick recap:
- ✅ Disbud early — ideally before day 7 for bucks and day 14 for does
- ✅ Burn a complete ring + center burn method
- ✅ Remove the horn bud cap
- ✅ Add a forward burn for buck kids
- ✅ Avoid ointments and allow dry healing
Even with perfect technique, some goats — especially bucks — may still develop small scurs. But with careful management, you can minimize complications and keep your herd healthy, hornless, and safe.
