Effects of pre- and postnatal flavour exposure on stress-related behaviour and postweaning performance in piglets

Research output: Chapter in Book/Report/Conference proceedingAbstract

Abstract

We aimed to study the effects of pre- and postnatal flavour exposure through the maternal diet on performance and behaviour of newly weaned piglets offered a similarly flavoured food. Sows (n=18) were offered anise-flavoured (F) or control (C) food during late gestation for 10 days. Piglets were cross-fostered after birth, with each sow fostering five piglets from an F sow and five from a C sow. During lactation, sows were offered F or C feed, resulting in FF, CF, FC and CC piglets (n=9 groups of each treatment). Piglets were weaned, relocated and mixed with unfamiliar same-treatment pigs (4 per pen, 2 of each sex) on day 25 and were given both control and anise-flavoured food for two weeks in a choice food approach. Pen averages for body weight, feed intake, diarrhea and behaviour were analyzed using a mixed model (repeated measures when appropriate) including pre- and postnatal exposure, their interaction and batch (two) as factors. No clear effect of exposure on anise preference was found. Prenatally exposed animals (FF+FC piglets) showed a higher food intake on day 2, 3 and 5 (on average 0.30±0.03 vs. 0.27±0.04 kg/pig/day, p
