Instructions: Fill in the fields with bold labels
below to evaluate the results of a product, and click on 'Calculate'.
For a detailed explanation, see the associated article "Pork
Per Tonne of Feed - A Measure of Efficiency" (link below).
(The same values for these factors are used in calculations for
both trials, even if they were different during the trials, to
allow the comparison of returns.)
For help interpreting the results, please follow the link to
the article in the "related links" section.
*Note: When considering something other than a feed additive,
etc., such as vaccination for example, you will need to calculate
the cost in terms of $/tonne of feed used for entry in this field.
Example: $2/pig x 100 pigs = $200 extra outlay. If 28 tonnes of
feed was used in the trial, then $200/28 tonnes = $7.14/tonne

in Pig Farming.)
