Response modifiers

A new feature was added to WinFeed 3 to allow the user to make use of their own expertise to modify the optimum feed composition or feeding programme. This tool can be found in the Response modifiers tab.

Its function is best explained by giving an example: pellet quality may be influenced by the feed fat content; given the difficulty to simulate this on a global scale, the user may utilise the response modifier to adapt the output to best suit them. The relationship between a modifier (in this case, feed fat) and a responder (feed fines) must be specified. Upon opening this option in the Optimiser, there will be an opportunity for Adding, Deleting or Editing Defaults.

Once Edit Defaults is selected:

Note that this modifier would then need to be applied to the appropriate feeds in the feeding programme. This can be done by clicking on the appropriate feed(s), selecting the modifier from the drop-down list and selecting Apply to feed.

Other examples of Response modifiers would be lysine digestibility vs. crude fibre content; downgrade % (i.e. hock burns) vs. dietary protein content (this is an example of a case where the modifier may only be required in the grower and finisher periods).
