The use of models in the life sciences has greatly expanded in scope and advanced
in technique in recent decades. However, the range, type and complexity of models
used in farm animal welfare is comparatively poor, despite the great scope for
use of modeling in this field of research. In this paper, we review the different
modeling approaches used in farm animal welfare science to date, discussing the
types of questions they have been used to answer, the merits and problems
associated with the method, and possible future applications of each technique.
We find that the most frequently published types of model used in farm animal
welfare are conceptual and assessment models; two types of model that are
frequently (though not exclusively) based on expert opinion. Simulation,
optimization, scenario, and systems modeling approaches are rarer in animal
welfare, despite being commonly used in other related fields. Finally, common
issues such as a lack of quantitative data to parameterize models, and model
selection and validation are discussed throughout the review, with possible
solutions and alternative approaches suggested.
