Helping you proactively manage summer heat.

The main observational factors of the Cattle Heat Load Toolbox

During the heat of summer there are a number of tasks that need to be undertaken on a daily basis to protect your herd from heat load.

Your SMS alerts are now active, and your e-mail alerts will continue to operate as they have all winter. It’s probably a good time to review your heat management strategies, ensure the essential staff have active CHLT accounts (and can log in!), check your weather station and make sure it’s uploading correctly to CHLT, and have a heat management meeting with all your staff to keep everyone up to date with your procedures and how to identify heat stress in animals.

The current Risk Assessment Program (or RAP) is being reviewed after MLA/ALFA identified some key areas that need further refinement and improvement. An extensive test will be undertaken this summer so that the new RAP can launch before next season 2019-20. In the meantime, now is the time to do your RAP (the existing version) and assess your risk for the coming summer.

System improvements

We’re always looking at alternative sources of forecast data to see if we can improve the base weather forecast. Currently, we are evaluating various sources to see if they will provide value, and we would love to hear from you to see what additional forecast information may be useful for your operations. Are you concerned about storms? Do you need a warning for dusty conditions? Is evaporation important? Drop us a line, or pick up the phone. We always love to talk about the weather!

As I’m sure you are aware, MLA commissioned UQ to undertake an R&D program to help identify deficiencies in the current HLI/AHLU model. We look forward to implementing any improvements into CHLT as they become available.

These new features are just another reason to get on board with the HLDN and make the most of your site specific data. If you need a hand in setting up your HLDN data feed please feel free to contact us for assistance. As always we are available for comments and suggestions throughout the season and are happy to help.
