Animal Wellbeing

Vital knowhow in every step - better monitoring, improved production: AfiAct II now monitors the animal resting time, health and wellbeing

Cows need to rest. Not only this is a major contributing factor to their wellbeing, but also - a calm cow, is a productive cow. Researches show that a lost 1 hour of resting time, becomes a loss of 1.7kg of milk in the tank!

When animals are not healthy, at early stages they already shows sign of changes in the behavioral patents. AfiAct II is highly effective at finding the health anomalies in these patterns.

What, and when - AfiAct II tags, along with AfiFarm 5.2 software allows you to monitor and be alerted when you need to act:

  • Sick animals based on rest behavioral pattern
  • Welfare index for each group, and general restlessness alert when needed
  • Overcrowding alerts - let you know when overcrowding develops, and in which group
  • Quality of bedding alert - time to improve the bedding! The animals are not resting enough, now we know why.
  • Group changes alert - too many group changes are causing restlessness in the group

Calving Alert Service

Vital knowhow in every step - Calving Alert Service

The best gotten better: AfiAct II leg tags, the best heat-detection solution in the market, are now enhanced with powerful new set of capabilities, thanks to AfiFarm 5.2 software

Determination of calving time can often be a difference of life and death for calves and cows.

With the AfiAct II calving alert service, you now receive notifications directly to your smartphone - just before calving starts, and more importantly, in cases of prolonged calving that often require intervention.

The AfiAct II Calving Alert Service was successfully proven at large scale, used in hundreds of farms in tens of countries to help farmers save their calves and cows every day.

  • Proven successfully, at large scale - used in hundreds of farms in tens of countries to help farmers save their calves and cows every day.
  • Time sensitive - AfiAct II calving alert service is the only tool today that alerts less than 4 hours before calving, and provides prolonged calving alerts
  • Easy - all you need is a smartphone. Notification will come in directly to your Farm Notification inbox, using Afimilk iOS or Android app.

Best Animal ID

How it works and what makes us better

Patented Unique Technology

Patented, Unique Technology - Provides Unmatched Heat Detection and Health Monitoring

Silent Herdsman Collar is the only one of it’s kind that uses 3D Accelerometer to effectively monitor different patterns of motion pattern: Chewing/Licking, Ruminating, and Full Body Activity.

Why would you care how it works? Because this is how, this sensor provides dramatically higher accuracy than other collars.

Heat Detection

Heat detection that stands out:

Silent Herdsman collar provides 95% sensitivity of detection, special algorithm to optimize for cows and heifer which behave differently, as well as closed barns vs. grazing regimes. For fertility management the system will list down:

  • Heat detection / Animals for insemination
  • Non-cycling cows and Repeatedly cycling
  • Administrative lists: Due heat and PD check

Monitor Animal Health

3 sensors in a single package - unique tool for health monitoring

Rumination is a sensitive and early indicator for health issues. The problem, is that other reasons may cause drop in rumination, and therefore it is highly susceptive to false alarms. Because we are combining the Rumination, Chewing, and Activity detection we can tell which is which and alert you on the cows with real health problem.

  • Ecoli mastitis
  • Ketosis / Acidosis
  • Rumen problems
  • Feet problems
  • Pneumonia
  • Cystic cows
