Differences between the calculators?

'Ask the Calculator'

The basic version is a three-step process designed to generate a quick estimation of pasture consumption.

  • Enter details about the farm milking area, the herd, feed produced on the farm and brought in feeds.
  • Pick questions of interest and the calculator provides answers relating to pasture consumed and the energy in the feeds on offer.
  • Answers are generated using entered details and industry averages.
  • Entries can be saved by creating an account. Users can ‘upgrade’ to the intermediate version and details are copied over. Note that additional information will be required to ensure the intermediate version works correctly.

Intermediate calculator

The intermediate calculator requires more inputs to achieve better estimates of pasture consumed on the farm milking area.

Entries can be saved by creating an account. Users can ‘upgrade’ to the advanced version and details are copied over. Note that additional information will be required to ensure the advanced version works correctly.

Advanced calculator

The advanced calculator requires more detailed inputs relating to feed provided to each class of stock. The result is a more personalised and accurate estimate of pasture consumed on the farm milking area. Feed test results and accurate estimations of cow liveweights are highly valuable for this level of calculator.

Feed test results and accurate estimations of cow liveweights are highly valuable for this level of calculator. This tool is designed for use by researchers and is based on the published paper:

Heard JW, Doyle PT, Francis SA, Staines MH, Wales WJ (2011) Calculating dry matter consumption of dairy herds in Australia: the need to fully account for energy requirements and issues with estimating energy supply. Animal Production Science, 51, 605-614.

Note that in addition, the calculator also provides an estimation of annual feed conversion efficiency of the milking herd plus estimates of tonnes of dry matter per 100 mm water used.
