Ageing Up Livestock (IAM)

Ageing livestock in IAM Management

🛠️ Manually Updating Age Classes

While AgriWebb automatically manages age class transitions, you may occasionally need to make manual adjustments — especially for unique management decisions, exceptions, or correcting data. Tracking accurate age classifications is essential not only for management decisions but also for maintaining up-to-date livestock reconciliation reports. These reports reflect your herd's current structure and any changes made to age classes. Ensuring accurate updates helps streamline operations and records.

You can update age classes for individual animals or in bulk via CSV. For more information on our age class distinctions, view this article.


✏️ Updating a Single Animal

To manually update the age class of an individual:

  1. Log in to the AgriWebb Web App.

  2. Navigate to the Livestock list and select the animal you’d like to update.

  3. Click Actions > Edit Animal.

  4. In the animal record, scroll to the Age Class field and select the appropriate category.

  5. Save your changes.

View our edit livestock article for further details.


📥 Bulk Updates via CSV

Need to update multiple animals at once? Use the CSV import tool:

  1. Create a .csv file with:

    • A unique identifier for each animal (e.g. EID or VID)

    • The desired Age Class​

  2. Go to the Livestock tab in the Web App.

  3. Click Import Animal Data > Import Animal Updates.

  4. Upload your CSV and follow the steps to complete the import.

✅ Tip: Double-check your age class labels in the CSV to ensure they match AgriWebb's supported classes (e.g. “Lamb”, “Weaner”, “Hogget”, etc.).

⚠️ Important Note on Bulk Updates

When you use the Import Animal Updates feature to manually update age classes via CSV, it will overwrite the animal’s age class permanently — past classes will not be recorded or visible in history.

🧩 Example:

If you bulk update a group of Heifer Calves to Heifers, their record will only show “Heifer” as their age class — there will be no reference to them ever being a Heifer Calf in their history.

⚠️ Resolving Date of Birth & Age Class Errors

You may see an error if an animal’s Date of Birth (DOB) doesn’t match its Age Class. Each class has specific age requirements. Example (Cattle):

  • Under 11 months → should be Calf or Steer Calf

  • 11–12 months → should be Weaner

  • Over 12 months → should be Yearling or older

✅ How to Fix Upload Errors

  • Update the DOB to match the correct age class

  • Or update the Age Class to fit the animal’s age

  • If needed, use a temporary valid class like “Heifer Weaner” until you can correct the record

💞 Adding a Natural Service Record

Adding a natural service record helps you track your breeding timeline and calculate a calving window for your herd. This record notes when sires were introduced and removed, providing a clear timeframe for when calves are expected.

To add a natural service record:

  • Select the Livestock Tab. This is typically the main section for managing your herd's information.

  • Add Records. Navigate to the option for adding a new record.

  • Natural Service. Choose the "Natural Service" record type from the list.

  • Enter the service start date and end date. The start date is when the sire was put in with the dams, and the end date is when the sire was removed. If the end date is not available, you can add it later.

  • Select the dams you want the record to be applied to.

  • Save. Finalise the record to calculate the calving window.
