ABSTRACT
The objective of this study was to develop a model to assess
economical and balanced feed rations for sport horses. It was based on nonparametric
modelling with a combination of linear programming and a multiobjective
optimization technique: weighted goal programming. The method
incorporates multiple goals into optimization. The technical data presented the
feed nutritional value (dry matter, metabolizable energy, metabolizable protein,
etc.) and nutritional requirements, which were represented in weighted
goal programming as targets. The model was tested for optimization of winter
and summer feed rations, where summer feed rations are more expensive but
more balanced. Optimization results show that the method of weighted goal
programming is more accurate and useful in practice compared with linear programming,
where only one goal (economically optimal feed rationing) is taken
into account.
