Prerequisites
- Processing transactions must be entered in Protein/Amino.
- Bird weight sensors must be connected to Sonar, with regular readings (e.g., every 15 minutes or every hour).
Benefits
- Validate the accuracy of Sonar’s bird weight algorithm, which calculates current bird weights.
- Confirm the accuracy of the bird weight projection algorithm.
- Automate the process of recording and comparing bird weights, eliminating manual analysis.
- Quickly assess weight and projection accuracy with color-coded statistics.
How It Works
When a processing transaction is entered in Protein/Amino for a Sonar farm, it is automatically uploaded to Sonar.
- For hardware that provides raw bird weights (e.g., Echo 1, Echo 2, certain Rotem controllers, BarnTalk, etc.), Sonar uses a machine learning algorithm to calculate the current bird weight.
- For other hardware, the controller calculates the bird weight, and the average is uploaded to Sonar.
- For all hardware types, Sonar uses a machine learning algorithm to calculate bird weight projections. Note: The accuracy of these projections depends on the accuracy of the current bird weight calculation.
On the Bird Weight Audit screen, you can select a date range to view the analysis. Sonar compares processing transactions from Protein or Amino with bird weights recorded in Sonar for the same date. The system then subtracts the shrink weight from the Sonar weight to generate a comparison.
The inputs for this comparison are:
- Begin Date / End Date: Defines the date range for the analysis.
- Standard Shrink Weight: The expected weight loss from the time feeders are raised to when birds arrive at the plant. This value is subtracted from the last recorded Sonar Live Weight for comparison with the processing weight.
- Target Difference: The acceptable range of error for bird weights and projections, used to set the red and green color indicators in the report.
The report displays all flocks sold within the selected date range and provides an analysis. The following columns are included in the comparison grid:
- Farm ID
- Farm Name
- Flock
- Product Name
- Date Sold
- Age
- Sonar Processing Weight: The last Sonar weight minus the entered standard shrink weight. For example, if the last Sonar weight is 5.00 lbs and the standard shrink is 0.20 lbs, the Sonar Processing Weight will be 4.80 lbs.
- Protein/Amino Processing Weight: The weight recorded in the processing transaction from Protein or Amino.
- Difference of Actuals: The difference between the Sonar Processing Weight and the Protein/Amino Processing Weight.
- Projected Weight 1 Day Out: The projected bird weight one day before processing, minus the standard shrink weight.
- Difference 1 Day Out: The difference between the Projected Weight 1 Day Out and the Protein/Amino Processing Weight.
- Projected Weight 3 Days Out: The projected bird weight three days before processing, minus the standard shrink weight.
- Difference 3 Days Out: The difference between the Projected Weight 3 Days Out and the Protein/Amino Processing Weight.
- Projected Weight 7 Days Out: The projected bird weight seven days before processing, minus the standard shrink weight.
- Difference 7 Days Out: The difference between the Projected Weight 7 Days Out and the Protein/Amino Processing Weight.
