6 Best Ear Notching Tools For Piglet Identification That Old Farmers Trust
Explore the 6 best ear notchers for piglet ID. Our review covers the durable, precise tools trusted by generations of farmers for permanent identification.
You’re staring at a dozen nearly identical piglets, and you know that in a few weeks, telling them apart will be impossible. Good record-keeping is the backbone of a successful small farm, and it starts with a permanent, reliable identification system. Ear notching is that system—a low-cost, time-honored method that, with the right tool, is simple, effective, and will last the pig’s entire life.

Why Ear Notching is a Time-Tested Method
Ear notching is the gold standard for a reason: it’s permanent. Unlike ear tags that can be ripped out on fences or lost in the mud, a notch is there for good. This method provides a visual record of an animal’s identity that you can read from across the pen without having to catch it.
The system itself is brilliantly simple. The pig’s right ear represents its litter number, and the left ear identifies its individual number within that litter. Specific locations on each ear are assigned a value (1, 3, 9, 27, 81), and by combining one or two notches, you can create a unique ID for every animal. It’s a language written on the animal itself, requiring no batteries, software, or expensive readers.
Many farmers shy away from it, thinking it’s complicated or cruel. The reality is that when done correctly on a piglet in its first few days of life, it’s a quick pinch that heals rapidly. It’s far less stressful than a poorly placed tag that gets infected later. Learning the system is a one-time investment of your time that pays dividends for decades.
Stone V-Notcher: The Classic Farmer’s Choice
When you picture an ear notcher, you’re probably thinking of a Stone V-Notcher. These tools are heavy, often made of forged steel, and built with an almost stubborn refusal to fail. This is the kind of tool you buy once and pass down to your kids.
Its primary strength is its sheer simplicity and durability. There are no complex mechanisms to jam or break. The V-shaped blade makes the standard, universally recognized notch that is easy to read. You get a clean, deep cut that is less likely to heal over and become unreadable as the pig grows.
The tradeoff for that durability is weight and a lack of modern ergonomics. If you’re processing a large litter, the heavy steel and basic handle design can lead to hand fatigue. A tired hand can make a sloppy cut, so it’s something to consider. But for pure, unadulterated reliability, the classic Stone is trusted for a reason.
Jorgensen U-Notcher for Clear, Lasting Marks
The Jorgensen U-Notcher offers a slight variation on the classic design with a rounded, U-shaped cut. Some experienced farmers swear by the U-notch, believing its curved shape is less prone to tearing or getting snagged as the ear grows and thickens. This can result in a cleaner, more legible mark in the long run.
Jorgensen is a brand known for making tools that hold a sharp edge. A sharp notcher is non-negotiable; a dull blade crushes tissue instead of cutting it, leading to pain, bleeding, and poor healing. The clean cut from a quality U-notcher helps ensure the mark remains distinct and easy to identify years later.
Ultimately, the V-notch versus U-notch debate comes down to personal preference and experience. The "U" shape can sometimes be easier to distinguish from a natural tear or nick the pig might get in its ear later in life. If you find V-notches are closing up or getting ragged on your pigs, a high-quality U-notcher like a Jorgensen is an excellent alternative to try.
Neogen V-Blade Notcher: Built for Durability
The Neogen V-Blade Notcher is a perfect example of taking a classic design and refining it with modern materials and manufacturing. These tools are often constructed from high-grade steel or aluminum alloys that are tough, corrosion-resistant, and engineered to stay sharp through countless uses. It’s a tool built for the farmer who appreciates tradition but demands performance.
A key feature you’ll often find on Neogen models is a spring-loaded handle. This might seem like a small detail, but it makes a world of difference. The spring action provides a smooth, consistent cutting motion and reduces the hand strength required for each notch. This means less hand fatigue and, more importantly, a greater likelihood of making a perfect, clean cut every single time, even on the last piglet of the day.
Think of the Neogen as the workhorse tool. It’s not a specialized gadget, but a robust, reliable piece of equipment that makes a routine chore easier and more efficient. For a small farmer processing a few litters a year, this balance of durability and user-friendly design is hard to beat.
Allflex Mini Notcher for Precision on Small Ears
Standard ear notchers can feel clumsy and oversized on a day-old piglet, especially with smaller breeds like Kune Kunes or American Guinea Hogs. Trying to make a precise 1/4-inch notch with a tool designed for a much larger ear can lead to mistakes—notches that are too deep, too shallow, or in the wrong spot. This is exactly the problem the Allflex Mini Notcher solves.
This tool is specifically scaled down for small ears. Its smaller jaw and blade allow for incredible precision, ensuring you can place each notch exactly where it belongs according to the universal numbering system. This is crucial because a poorly placed notch can be misread later, defeating the entire purpose of identification.
The Allflex Mini is a specialist’s tool. It’s not what you’d grab for a three-week-old piglet you missed, as it may not be robust enough for thicker ear cartilage. But for getting the job done right on newborns, its precision is unmatched. Having one on hand is a smart move if you work with smaller breeds or prefer to notch within 24 hours of birth.
Nasco Cast Aluminum Notcher: A Lightweight Tool
If you’ve ever notched a litter of 14 piglets with a heavy, all-steel tool, you know that your hand gets tired. The Nasco Cast Aluminum Notcher directly addresses this issue. By using lightweight cast aluminum for the body, it significantly reduces the tool’s overall weight without sacrificing the strength needed to cut through a piglet’s ear cartilage.
This focus on user comfort is a game-changer, especially for anyone with less hand strength or a touch of arthritis. A lighter tool allows for better control and a quicker, more confident motion. This isn’t just about your comfort; a more controlled cut is better for the piglet, leading to a cleaner notch and faster healing.
Some might question if aluminum is as durable as traditional steel. For the task of notching young piglets, a well-made cast aluminum tool is more than adequate and has the added benefit of being naturally rust-resistant. It represents a smart use of modern materials to make a timeless farm chore a little bit easier on the farmer.
SyrVet Stainless Steel Notcher for Easy Cleaning
Biosecurity is not just for big operations. On a small farm, preventing the spread of infection is just as critical, and the SyrVet Stainless Steel Notcher is designed with hygiene as a top priority. Stainless steel is non-porous and exceptionally easy to clean and sterilize between animals.
With a standard steel notcher, you have to be vigilant about drying it to prevent rust, which can harbor bacteria. With a stainless tool, you can confidently dunk it in a jar of disinfectant like Nolvasan or Virkon-S between each piglet. This simple step drastically reduces the risk of transferring infections from one animal to another.
This isn’t just about ticking a box for "best practices." A clean tool makes a clean wound. A clean wound heals faster, causes less stress to the animal, and results in a crisp, easy-to-read notch. The SyrVet notcher makes it easy to do the right thing, ensuring the health of your piglets is never compromised by your equipment.
Proper Notching Technique and Piglet Aftercare
The best tool in the world is useless without proper technique. The key to successful ear notching is to do it early, ideally between 1 and 3 days of age. The cartilage is soft, the piglet is small and easy to handle, and they recover almost instantly.
The process should be quick and confident. First, secure the piglet firmly but gently. Have your numbering chart handy so you know exactly where the notches go. Wipe the edge of the ear with an antiseptic wipe or a cotton ball soaked in iodine. Position the notcher and make a swift, decisive cut. Hesitation leads to sloppy notches.
- Depth is critical: The notch should be about 1/4 inch deep on a small piglet. Too shallow, and it will heal over; too deep, and you can damage the ear’s structure.
- Spacing matters: Leave at least 1/4 inch of space between notches on the same ear to ensure they remain distinct as the pig grows.
After notching, a quick spray of veterinary antiseptic or a dab of blood-stop powder is all that’s needed. Place the piglet back with its mother immediately. Check the ears over the next few days for any signs of swelling or infection, but with a clean tool and good technique, complications are extremely rare. The whole process for one piglet should take less than 30 seconds.
Choosing the right ear notcher comes down to your priorities—be it the bomb-proof durability of a classic Stone, the lightweight comfort of a Nasco, or the hygienic design of a SyrVet. More important than the brand, however, is the practice. A sharp, clean tool combined with a confident technique ensures this permanent ID system is humane, effective, and a cornerstone of your farm’s records for years to come.
