The heat score shows the likelihood that an animal is in heat. It’s calculated by Nedap Now based on real-time sensor data and is displayed on a 1 to 5-star scale: 

• A 5-star rating signals a strong heat, making the animal a good candidate for insemination 
• Heat scores appear in the In Heat worklist and on the reproduction graph.

How is the Heat Score Determined?

The heat score is based on three key factors: 

• Cyclicity: Whether the animal is in a fertile phase

• Pregnancy status: Animals confirmed pregnant are excluded 

• Activity level: Increased movement is a strong heat indicator

The system uses sensor data and historical behavior to assign stars. While increased activity often signals the start of a heat, the heat score may take some time to update as more data is collected. 

Understanding Star Ratings and Colors

Star Ratings

• 1–2 stars: Minor increase in activity
  Only considered a heat when confirmed by user judgment

• 3–5 stars: Significant increase in activity
  Typically indicates a true heat

Star Colors

Each heat is assigned a default color based on its star rating: 

• 1-2 star heats are grey by default.
• 3-5 star heats are green by default.

User judgement can override default colors:

• Negative judgment (No heat): Stars turn grey.
• Positive judgment (In heat): Stars turn green.

Adjusting Heat Score Sensitivity

You can fine-tune the sensitivity settings to better align heat detection with your herd's behavior.

Example: Reading a Heat Score

The reproduction graph may show combinations like: 

• A confirmed heat followed by insemination. 
• A mild activity increase with a negative user judgment (not considered a true heat).
• A current heat still awaiting confirmation
