Detect and Treat Illness Ahead of Time

Changes to an animal's eating and drinking behaviours are the earliest indicators of illness and distress. HerdWhistle works 24/7 to track every time an animal eats or drinks, alerting you to potential signs of issues up to 7 days sooner than visual inspections.
