Unsanitary conditions led to poorer piglet performance and health status, predominantly during the 1st age period. The reduced daily gain appeared to be due to the decrease of feed intake at IFIP, while it was hypothesized at INRA that a lower digestion and/or absorption of nutrients occurred. During the 2nd age period, performances were similar indicating that the previous period led sufficient time to adapt to a poorer environment. The effects of fibre did not depend on husbandry conditions. Whatever they were, fibre improved daily gain during the 1st age period, while during the 2nd age period, daily gain and feed efficiency were decreased by fibre; fibre also increased transiently diarrhoea frequency. No effect of fibre on plasma haptoglobin levels was
detected.
