Time-lapse video recordings were made over 24-h periods on 32 halothane-negative pigs (NN) and halothane-positive pigs (nn) and on 16 of their progeny (Nn). Ethograms constructed from the tapes revealed that halothane-positive pigs drank and ate less frequently and spent longer investigating their pen, than halothane-negative pigs or the progeny (P<=0.01). Halothane-positive pigs also slept more frequently in groups and were less aggressive than the other 2 genotypes (P<=0.01). Halothane-positive pigs and the progeny displayed a greater level of neutral/non-aggressive acts, including nose-nose and nose-body contact than the progeny (P<=0.01). However, when fasted for 24 or 48 h, all genotypes behaved similarly, with a low level of most of these behavioural traits. These results suggested that there are differences in behaviour among the 3 genotypes.
