How Do You Properly Implement Smart Ear Tags on Your Farm?

Worried about a failed smart tag rollout? Poor planning leads to lost data and wasted investment. Let's ensure your project succeeds from the start.

A successful smart ear tag implementation involves three key stages. First, conduct a thorough site survey to select the right tech. Second, follow a standardized installation protocol. Finally, perform post-installation checks to ensure data accuracy and animal welfare. This structured approach guarantees a smooth and effective rollout.

Implementing new technology on the farm can feel overwhelming. You've got the hardware, but a successful rollout is about more than just the tags themselves. It's about a clear, step-by-step process that accounts for your unique farm environment. Let's break down exactly what that process looks like, starting from the very beginning.

How Do You Conduct a Thorough Site Survey Before Installation?

Choosing the wrong tech or ignoring site-specific risks can doom your project. A site survey identifies these issues before they become costly problems.

A proper site survey involves four critical steps. First, choose the right tag type (NB-IoT, LoRaWAN, or BLE) for your herd size and area. Next, plan your cow restraint method. Then, determine base station placement. Finally, test signal strength and assess potential risks like tag loss.

A site survey is the foundation of your smart farming project. I've seen projects struggle because this step was rushed. You need to get out in the barns and fields. First, you must select the correct ear tag technology. This decision depends on your farm's layout and herd size.

Next, look at your existing facilities. Do you have headlocks or chutes? If not, you'll need ropes and more hands on deck. Also, plan where to install gateways if you're using LoRaWAN or BLE. They need 24/7 power and should avoid large metal barriers. Finally, assess risks. Don't use smart tags on tethered cattle, and if your farm has a high rate of losing regular tags (over 20%), you need to address that first.

What's the Correct Way to Physically Install Smart Ear Tags?

You have your plan and your tags. But improper installation can cause data errors, infections, or lost tags.¹ A standardized process is essential for success.

First, check the new tags on the data platform to ensure they're working. Then, disinfect the tags and change the pin on your applicator. Scan the tag's QR code to link it to a specific cow's profile in the app before securely attaching it to the ear.

When the tags arrive, don't just rush to install them. I always start with an "initial check." Log into your data platform and verify the new tags are online. Their temperature readings should be close to the ambient temperature, and the battery voltage should be above 2.95V. This simple check saves a lot of headaches later.

Once you've confirmed the tags are good to go, you can begin the physical installation.

1. Prepare: Swap the standard pin on your ear tag applicator for the special pin provided with the smart tags. Then, soak the smart tags in 75% alcohol for at least 30 minutes to disinfect them.
2. Log Data: This is crucial. Before attaching the tag, use the mobile app to scan its QR code. This links the tag to a specific animal. Enter all the important details: breed, birth date, health records, etc.
3. Attach: Securely restrain the cow. Place the tag in the applicator and attach it to the inner part of the ear, closer to the head. This position significantly reduces the chance of it getting snagged and falling off. If your NB signal is weak, you can try attaching the tag to the back of the ear.

What Checks Are Necessary After Attaching the Ear Tags?

The tags are on, but the job isn't done. Without follow-up, you might miss installation errors, leading to data gaps or animal health issues.

After installation, perform both data and physical checks. Monitor the data platform for at least two upload cycles to spot any anomalies. Physically inspect the ear for a week to check for signs of infection, swelling, or issues with the tag snagging on equipment.

I always tell my clients that the first week after installation is critical. Your job is to observe and verify. Start with the data. Log into your platform and watch the data come in from the newly tagged cows. You should monitor it for at least two full upload cycles. If a tag shows strange readings or fails to report, it may be faulty or damaged during installation and needs to be replaced immediately.

At the same time, you need to do physical checks.

• Placement: Right after attaching, double-check the tag's position. If it’s too close to the edge of the ear, it’s likely to get torn out. You need to cut it off and apply a new one correctly.
• Animal Health: For the next week, keep a close eye on the cows' ears. Look for any excessive redness, swelling, or pus, which could signal an infection.
• Snagging: Also, observe how the tag interacts with your farm equipment. Is it getting caught on headlocks, fences, or water troughs? A well-designed tag shouldn't, but it's always best to check. This final step ensures the long-term success of your system and the well-being of your herd.

Conclusion

By following a careful process of surveying, installing, and checking, you can successfully implement smart ear tags, boosting your farm's efficiency and your herd's health.²
