Abstract

In ten 1-hour segments of videotaped behaviour of 20 swine, half of the segments showed the behaviour of recently re-grouped and aggressive pigs and the remaining segments were of the later socially-stable groups. Attack, feeding, drinking, lying, moving and standing were recorded. Time-sampling (recording less than the full periods) resulted in acceptable correlations and mean values when sampling periods were greater than 20 minutes per hour. Focal animal sampling was an accurate sampling technique for all types of behaviour except attack. Observing videotapes at 4 times faster than life provided an accurate sample of behaviour, but viewing tapes 24 times faster than life was inaccurate for drinking and feeding behaviour. These results highlight the need for validation of sampling techniques for studies measuring pig behaviour.
