*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 of feed.

(PTF Calculator was developed based on articles by John Gadd in Pig Farming.)
