In modern livestock farming, identity verification at passage gates is a critical component of digital farm management. RFID livestock Tags gate identification technology enables automatic animal identification and real-time data collection by deploying RFID equipment at key locations such as passage gates, weighing stations, and sorting gates. This provides a reliable data infrastructure for end-to-end livestock management.
System Components
Fixed RFID Ear Tag Readers
- Panel RFID Ear Tag Reader
- Dual-Core Dual-Antenna RFID Ear Tag Reader
RFID Electronic Ear Tags
- Low Frequency (LF) 134.2 kHz RFID Electronic Ear Tags
Technology Overview
RFID livestock gate identification is based on Low Frequency (LF) 134.2 kHz RFID technology. When an animal wearing an RFID ear tag or implanted transponder passes through the reading zone, the reader antenna generates an electromagnetic field that powers the passive tag. Once activated, the RFID chip transmits its unique identification (ID) back to the reader. The reader then uploads the data to the management system, completing identity verification and linking the animal with corresponding operational records.
The entire process is fully automated, requires no manual intervention, and is designed to operate reliably in demanding livestock environments with high humidity, dust, and electromagnetic interference.
In-Depth Analysis: Five Key Questions
- How Does an RFID Livestock Gate Identification System Work?
The complete workflow consists of the following steps:
- Tag Activation: The reader antenna generates a 134.2 kHz electromagnetic field to power the passive RFID ear tag.
- Data Transmission: The tag reflects its unique ID to the reader through signal modulation.
- Signal Decoding: The reader decodes the ID using HDX or FDX-B protocols.
- System Upload: Data is transmitted to the livestock management platform via Modbus RTU or network interfaces.
- Data Verification: The system filters duplicate reads and eliminates interference.
- Business Data Association: The animal ID is automatically linked with weighing, milking, sorting, feeding, and other operational data in real time.
- What Are the Reading Distance and Animal Passing Speed?
Under interference-free conditions, the reading distance can reach up to 90 cm. A dual-core dual-antenna reader uses a face-to-face antenna configuration that significantly reduces missed reads.
At a normal animal walking speed of 1–2 meters per second, the system maintains a reading accuracy exceeding 95%.
- What Are the Advantages of Fixed RFID Gate Readers Compared with Handheld Readers?
Handheld RFID readers require operators to approach each animal individually, resulting in high labor costs, lower efficiency, and delayed data collection.
Fixed RFID gate readers provide automatic identification as animals pass through the gate, offering three major advantages:
RFID Chip in Ear
- Automated Data Collection: No manual scanning is required, reducing labor costs by approximately 70%.
- Real-Time Data Synchronization: Seamlessly integrates with weighing scales, milking equipment, and other automated systems to ensure immediate data updates.
- Error Prevention: The system automatically validates the consistency between animal IDs and operational data, minimizing identification errors.
- What Applications Is the System Suitable For?
Typical application scenarios include:
Weighing Stations
When animals step onto the scale, their weight is automatically associated with their RFID ID, enabling continuous growth tracking.
Milking Parlor Entrances
As dairy cows enter rotary or parallel milking parlors, RFID identification is triggered automatically, and milk yield is recorded directly in each animal’s profile.
Automatic Sorting Gates
The system identifies each animal and automatically opens the appropriate gate according to housing group, production stage, or management rules.
Livestock Counting
Animals are counted automatically as they pass through the gate, eliminating manual counting errors and handwritten records.
Feeding Stations
Each animal is identified before feeding, allowing customized feed formulas to be dispensed for precision nutrition management.
UHF 860-960 MHz Livestock RFID Ear Tag
- Does the System Support Customized Deployment?
Yes.
Multiple reader models and antenna sizes are available to accommodate different animal species, including pigs, sheep, goats, cattle, horses, and camels.
Customization options include:
- Multi-protocol compatibility
- Ruggedized designs for harsh environments with operating temperatures from -25°C to 75°C
- Standard Modbus RTU and TCP/IP interfaces for third-party system integration
A typical implementation schedule includes:
- Solution design: 1–3 days

- System integration and commissioning: 2–3 days
- Operator training and project handover: 1 day
For emergency support, technical response begins within 30 minutes, with on-site service available within 8 hours for customers located within the province.
Practical Applications
Inner Mongolia Livestock Farm: Faster Livestock Inventory
A dual-core dual-antenna RFID system was installed at the exit gate to automatically identify and count animals during shipment. Compared with traditional manual counting, inventory time was reduced from half a day to just one hour, significantly improving operational efficiency.
Beijing Dairy Farm: Automated Milk Production Recording
RFID readers integrated at the entrance of a rotary milking parlor automatically identify each cow before milking. Milk production data is instantly linked to the individual animal’s digital record, eliminating manual data entry errors and enabling automatic daily production reporting.
Shandong Slaughterhouse: Enhanced Traceability Management
RFID readers installed at the receiving gate automatically associate each pig with quarantine certificates, farm-of-origin information, and transportation records, creating a complete traceability chain that meets food safety and regulatory requirements.
Russia: Large-Scale Digital Livestock Management
A dairy farm with 5,000 cows deployed 50 RFID readers across milking parlors, weighing stations, and sorting gates. The system established a comprehensive lifecycle management platform, enabling data-driven livestock management and smarter operational decision-making.
