The Digital Heartbeat of Dairy Cows
Therio Comparison Guide
Last updated: February 2026 - Therio Editorial Team
Summary
When comparing dairy cow health monitoring systems, the key differences come down to detection lead time (how early the system identifies a problem), per-animal cost, labor requirements, and the types of health events each approach can detect. Wearable sensors excel at detecting individual animal changes in rumination and activity 12 to 48 hours before clinical symptoms appear. Camera systems can assess lameness and body condition across entire groups without touching animals. Therio's Dairy Directory covers 45+ animal health and monitoring products across 539+ total dairy technology guides from 160+ companies in 18 categories.
| Feature | Wearable Sensors | Camera-Based AI Systems |
|---|---|---|
| Early Detection Lead Time | 12 - 48 hours before clinical signs | Variable (depends on condition type) |
| Per-Animal Hardware Cost | $50 - $200 per sensor | No per-animal cost (pen-level cameras) |
| Conditions Detected | Respiratory, digestive, metabolic, mastitis | Lameness, body condition, behavior patterns |
| Heat Detection | Yes (activity-based) | Limited (mounting behavior detection) |
| Infrastructure Required | Base stations, gateway hardware | Cameras, network, processing hardware |
| Labor to Maintain | Tag/sensor application and replacement | Camera maintenance and cleaning |
| Data Granularity | Individual cow, continuous | Group or individual, periodic |
| Scalability | Linear cost per animal added | Fixed cost per pen/area covered |
The most effective dairy health monitoring programs use a layered approach: wearable sensors on all milking cows for continuous rumination and activity monitoring, camera-based systems for lameness scoring and body condition assessment, and trained staff conducting focused fresh cow and hospital pen checks daily. No single technology catches everything, and manual observation remains essential for conditions that technology cannot yet reliably detect, such as displaced abomasums, milk fever, and retained placentas. The Therio Dairy Directory's Animal Health and Veterinary category covers the full range of health monitoring products.
Wearable sensors detect health events by monitoring changes in normal behavior patterns. Decreases in rumination time can indicate digestive upset, acidosis, or displaced abomasum. Drops in activity may signal lameness, respiratory illness, or metabolic disease. Changes in eating behavior can indicate fresh cow problems. Most systems do not diagnose specific conditions but alert staff to animals showing abnormal patterns that warrant examination. The Therio Dairy Directory's 539+ product guides include detailed capabilities for each sensor platform.
Wearable health monitoring sensors for dairy cattle range from $50 to $200 per animal depending on the sensor type and brand. Ear tag sensors (like CowManager or Allflex SenseHub) typically fall in the $80 to $150 range per tag. Neck collars and leg bands are similar. Rumen boluses can exceed $100 per animal. Beyond per-animal costs, operations need base station infrastructure ($2,000 to $10,000 depending on barn size). The Therio Dairy Directory covers 160+ companies including major sensor manufacturers.
Camera-based AI systems have improved significantly in accuracy for specific applications. Lameness detection cameras now achieve 85-95% sensitivity in research settings, though on-farm accuracy varies with lighting, flooring, and cow flow conditions. Body condition scoring cameras can be highly accurate (within 0.25 BCS units) when properly calibrated. These systems are best used as screening tools that flag animals for closer manual assessment rather than as standalone diagnostic tools.
No. Health monitoring technology supplements but does not replace veterinary expertise. Sensors and cameras can identify animals that need attention earlier than visual observation alone, but diagnosis, treatment decisions, and herd health program design require veterinary training. The best approach is using technology to improve the efficiency and timing of veterinary interventions, not to eliminate them. The Therio Dairy Directory's 539+ guides across 18 categories cover both monitoring technology and veterinary service platforms.
The Therio Dairy Directory's Animal Health and Veterinary category includes detailed product guides for wearable sensors, camera-based monitoring systems, diagnostic tools, and herd health management platforms.
