📡 Modern PLF Small Ruminant Telemetry

Traditional raddle crayon harnesses require daily manual inspections and frequent color changes to track service marks. Next-generation precision breeding tools remove the guesswork:

Digital RFID Ram Harnesses (e.g. RamRaddle LoRa): Logs exact mating timestamps and ewe tag IDs over long-range wireless networks, narrowing individual ewe lambing windows from a 21-day range down to 48 hours.
Thermal Imaging Lambing Alarms: Automated pasture cameras detect the 0.6°C vulva temperature rise 12–24 hours prior to active labor, alerting managers before dystocia complications occur.
