Livestock Tracking Wearables

Nofence, Halter and Afimilk are among the companies active in livestock tracking wearables. Nofence and Halter are associated with GNSS collars and virtual fencing, while recent news also reports Monil’s U.S. collar launch in July 2026 and Quectel’s GPS ear tag announcement in October 2026. These examples span collars, tags and connected herd-management systems.

Nofence and Halter are prominent startup names in the 2026 activity. Nofence introduced its N3 cattle collar and management platform in September 2026, while Halter raised a $220 million Series E round in March 2026. Their activity centers on GNSS collars and virtual fencing; these signals show market momentum but do not establish which company will perform best.

Texas A&M University, the University of Cordoba and the USDA Agricultural Research Service are active research organizations in this field. Texas A&M researchers compare GPS collars with solar-powered ear tags. University of Cordoba researchers study GNSS and Bluetooth data for cattle behavior, including calving and reproductive monitoring, while USDA Agricultural Research Service researchers evaluate collars for monitoring foraging behavior.

The tracked funding data records $198,656,000 across 4 rounds and $4,766,961 across 7 grants since 2020. These are separate totals for rounds and grants, not a combined figure. Halter’s $220 million Series E in March 2026 is a notable recent company funding announcement, but it is not the same as the rounds total reported in the funding data.

Halter’s $220 million Series E, reported in March 2026, is the latest clearly identified company round in the recent information. The round was led by Founders Fund, according to the March 2026 news. The funding records also contain other dated entries, but they do not identify a later company round specific to livestock tracking wearables.

Lely, Planettech and Phenogen Medical Inc each hold one listed patent, so no single organization leads the listed holders. The data records 3 patents in the 24-month window. These holder counts show a small set of named patent owners, but do not by themselves establish the commercial importance or technical scope of each patent.

The data records 3 patents in the 24-month window, but does not provide a patent-growth rate. The annual series lists 1 patent for 2025, while the recent-window count covers a separate period. With a small number of filings and no growth percentage available, the data does not support a clear conclusion that patent activity is rising or falling.

The main approaches are GNSS positioning, radio-based positioning, RFID and proximity, inertial sensing, and hybrid sensor systems. GNSS supports broad-area tracking; radio methods rely on local infrastructure; RFID and proximity identify animals or nearby interactions; and inertial sensors infer movement. Hybrid systems combine signals for richer monitoring, but increase device and data complexity.

The main applications are grazing and rangeland management, dairy herd management, beef and ranch operations, and traceability and biosecurity. Grazing and rangeland management has 105 associated documents, while dairy herd management has 103. Wearable data can help locate animals and monitor movement, supporting pasture decisions and herd oversight.

The United States leads the recorded geographic activity with 2,280 documents, followed by the United Kingdom with 785 and Germany with 612. China has 506 and Japan has 453. These country figures describe document activity, not company market share or the number of deployed devices, and should be read as an indicator of research and industry attention.
