Abstract

The responses of individual growing pigs to 60 stimuli from five sensory categories were evaluated as an initial step in developing a behavioural measure of welfare. Rigs were exposed to the stimuli in a test pen after beingtrained to eat from a food box adjacent to a stimulus presentation box. The pen design allowed easy expression of approach/avoidance behaviour by thepig. Five variables were measured - change in mean approach/avoidance distance from the food box, change in frequency of elimination, change in frequency of turning away from the stimulus box, latency to return to the food box after stimulus presentation, and latency to enter the stimulus box. The most robust measure of responsiveness was change in approach/avoidance distance, The strongest and most consistent aversive responses were obtained toauditory stimuli. There was little or no response to olfactory stimuli. Only two visual stimuli, which incorporated a black cross on a yellow background, elicited strong aversive responses. Other novel visual stimuli elicited positive responses. Responses to tactile stimuli were generally positive,mainly because they were administered by the experimenter and the pigs were familiar with handling by humans. Because there was significant variationbetween individual pigs, we propose that stimuli, which elicit high responsiveness but with little variation should be used in future tests of differences in responsiveness between treatments that may be indicative of stressed and unstressed pigs.
