BeefConnect Webinar: A new approach to ‘Adult Equivalent’ methodology

Beef Central, 06/06/2014

The Adult Equivalent (AE) is the standard measure of grazing loads used in extensive cattle grazing areas across northern and pastoral Australia.

Despite its common use, the measure has been inconsistently defined and applied and this has limited its application and utility.

A practical, defendable methodology has been developed which provides an accurate, consistent means of calculating cattle grazing loads for production systems across northern Australia.

The methodology calculates the energy demand of cattle based on animal specific variables. The calculated energy demand is expressed relative to the energy demand of the Adult Equivalent standard unit, ie a 450 kg Bos taurus steer at maintenance.

A spreadsheet based tool has been developed which applies the methodology to whole herd or individual classes of animals. It also generates a suite of tables which give AE ratings based on various physiological variables.

Join Ian McLean and Shane Blakeley from Bush Agribusiness Pty Ltd  as they discuss:

3. Issues with having standard measure for North

  • Diet quality
  • Distance walked

4. Tools and tables developed

5. Demonstration of tools
