In intensive pig production systems piglets are weaned at between 21 and 28 days of age and it is common for piglets to take a few days to discover and accept solid food as a source of nutrients and this results in a loss of weight (the weaning growth lag). Therefore, if a means could be found to encourage the acceptance of solid food by piglets, benefits in terms of their growth and welfare would ensue. The transmission of information about foods from one animal to another has been demonstrated in the rat (Galef, 1993) and ruminants (Provenza and Balph, 1987) but there have been no studies with pigs at the time of weaning. Therefore, piglets were tested in pairs of experienced and inexperienced animals, with varying degrees of contact, with constant access to food over a period of seven days after weaning of the inexperienced animals.
