The results of the research could potentially be applied in a PLF
system. There are several potential advantages of using PLF technology
in relation to the problem of aggression among pigs. PLF
technology can aid a task of gathering information about the animals
behaviour, even with large flocks or herds (Frost et al.,
1997). Sensors are not restricted to the sensory modalities of human
observing pigs: infra-red thermography can provide novel
information about animal temperature, for example. The common
features of sensors used in PLF are continuous, simultaneous
