Campylobacter levels in ceca^# (C) (log CFU/g) and litter* (L) (log MPN/g) during first thin-out and final pick-up on Farms 1 (F1, 2009–2010) and Farm 2 (F2, 2010–2011) in new, partial and full re-use litter treatments across six farming cycles (Cy1, Cy2, Cy3, Cy4, Cy5, Cy6).

^#Mean of C1, C2, from brooder end and C3, C4 from grow-out end of a shed of allocated treatment.

*Mean of L1, L2 from brooder end and L3, L4 from the grow out end of shed of allocated treatment.

**All treatments equal during C1 (cycle 1).

^∧During cycle 5 Farm 1 was picked up early.

^∧∧All three litter treatments were in place but run as a free range cycle.

nd, not detected(minimum detection - litter log 0.6 MPN/g and ceca log 2 CFU/g).

^a,bWithin farms, cycles and pickups - treatment means with different superscripts are significantly (P < 0.05) different.
