Knowledge of eliminative behaviour in pigs is of much importance for the design of housing systems in order to minimise soiling of the lying area. 53 piglets, 136 fatteners, 272 finishers and 277 sows were observed as focal animals at regularly used dunging areas in a highly structured housing system. Statistically significant transitions between behavioural elements were identified by means of a sequential analysis. The typical sequence of behavioural elements was: enter dunging area, sniff, posture, defaecate/urinate, sniff. For defaecation and urination, the percentage of sniffs classified as 'close to wall' was significantly higher before than after eliminative behaviour whereas the percentage of sniffs classified as 'close to floor' was significantly lower before than after eliminative behaviour. It is concluded that sniffing behaviour is temporally associated with eliminative behaviour in pigs.
