A model on feeding and social interaction behaviour of pigs (1.0.0)

This model simulates feeding and social interaction behaviour of commercially group-housed pigs. Pigs in the model express their behaviour based on their internal motivations and environmental conditions. Their motivations are affected by their internal physiological states (e.g. energy balance, stomach load, feeding drive and satiation) and external situation (e.g. food-related competition level and displacement at the feeding place). The model increases understanding of interaction between internal physiological factors and external social factors underlying behaviour of pigs. Furthermore, the model shows the effect of behavioural strategies of pigs (e.g. avoid or approach) to food-related competitive situations in various feeding and social interaction patterns.

Two model versions exist:
Version 1.0.0 (referred to as model 3 in the ODD) and version 1.1.0 (referred to as model 4 in the ODD). Both models simulate feeding and social behaviour of pigs, but differ slightly in testing the effect of various behavioural strategies and social factors (model 3) and testing the effect of individual variation among pigs (model 4).

Release Notes

Two model versions are released (the version of may 2017 and the version of february 2018).
