How do I use the HLI Threshold Calculator?


Select the characteristics and conditions of your highest risk cattle via the dropdowns. Once complete the HLI Threshold Calculator will generate the HLI Threshold for your operation, which provides you with the reference point for interpreting AHLU forecasts relevant to your site.

For example, the AHLU80 forecast refers to the AHLU where the HLI threshold = 80.

CHLT forecasts are provided for AHLU80, AHLU83, AHLU86, AHLU89, AHLU92 and AHLU95.

Where your HLI threshold falls between two AHLU reference points, you need to either estimate the AHLU, or, for a conservative approach, refer to the AHLU for the HLI threshold that is closest to, but less than, the calculated HLI threshold.
