Animals on 19 commercial farms were studied. The level of fear of humans by sows was assessed by observing their approach behaviour to an experimenter in a standard 3-min test.The time taken to enter an area within 0.5 m of the experimenter was related to farrowing rate (P<0.01). The use of verbal effort in moving pigs and the number of physical interactions of an intense negative nature (e.g. slapping the animals) were positivity (P<0.01) related to litter size. It was concluded that reproductive performance could be improved by employing stockpersons that have desirable attitudinal and behavioural profiles.
