Moocall HEAT is designed to detect the majority of heats, using the natural behaviour of the bull.
It is as accurate as your bull and enhances this by monitoring activity 24/7.
Proven Performance
Based on field data from users in Ireland in 2020:
96.5% submission rate within 3 weeks
~80% in-calf rate within 3 weeks
This is significantly above the national average of:
~64% in-calf rate (Teagasc benchmark)
How the System Detects Heat
The collar continuously monitors the bull’s behaviour, including:
Movement and activity
Time spent with specific cows
Proximity to RFID tags
These three key factors allow the system to identify when a cow is in heat:
Time + Activity + Proximity = Heat detection
Why It Works So Well
The system builds on the most reliable heat detection method available: the bull
Bulls naturally detect silent heats and short cycles
The collar acts as an electronic version of a chin-ball harness
It captures activity that may be missed by visual observation
Important Factors That Affect Accuracy
While the system is highly accurate, performance depends on correct setup and conditions:
1. Outdoor vs Indoor Use
Designed primarily for outdoor use
Indoor use (especially overcrowded sheds) can:
Reduce mounting activity
Lower detection accuracy
Increase false alerts
2. Bull Performance
The system relies on the bull:
A healthy, active bull = best results
A tired, lame, or inactive bull = reduced detection
3. Tagging All Animals
All cows with the bull must be tagged
Untagged cows can:
Affect system thresholds
Lead to missed heats
4. Correct Cow-to-Bull Ratio
Recommended: 1 bull per ~50 cows
Too many cows → reduced interaction
Too many bulls → conflicting activity
What About Missed or False Heats?
Like any system based on animal behaviour:
Some heats may be:
Silent or very short
Low activity
Occasional false alerts may occur due to:
Grouping animals in yards
Feeding times
Excess activity or disturbance
These can usually be managed with:
Exclusion zones
Proper setup and ratios
Summary
Moocall HEAT delivers:
High accuracy based on natural bull behaviour
Proven results above national averages
Continuous monitoring that reduces missed heats
Remember: The better the setup (bull, space, tagging), the better the results.
