Abstract

Previously we found positive effects of perinatal flavour exposure to anethol (anise) through the maternal diet on food intake, growth and behaviour of piglets after weaning when provided with anise-flavoured food. The food was not preferred, suggesting that the familiar flavour may have reduced weaning stress which was investigated in the current study. Sows were offered an anethol-flavoured diet (Flavour treatment) or control diet (Control treatment) during late gestation and lactation. Piglets were provided with anethol in their food (Feed treatment) or in the air (Air treatment) after weaning. Flavour piglets showed the shortest latency to eat after weaning. Flavour-piglets also played more, indicating low stress, especially in the Air-treatment. Control-pigs vocalized more on day 1 postweaning and directed more oral behaviour towards pen mates, which is likely the result of high stress levels. Salivary cortisol levels tended to still be higher 7 hours postweaning for Control-Air piglets compared to Flavour-Air piglets. Perinatal flavour learning decreased stress in newly weaned piglets, yet it seems not necessary to provide the flavour in the food to obtain such effects.
