Abstract

AIMS:

The effect of batch depletion of broiler houses for campylobacter occurrence in broiler flocks was estimated in 10 flocks, each comprising a separate female and male batch.

METHODS AND RESULTS:

The chicks were sampled first by cloacal swabs in the broiler houses before the start of the depopulation and secondly, on arrival at the abattoir. Females were slaughtered at 5 weeks of age, males at 6 weeks. The number of campylobacter-positive batches increased from five to seven female batches, and from five to 10 male batches, between the two sampling rounds.

CONCLUSION:

It is concluded that batch depletion of broiler houses increased the prevalence of Campylobacter spp.-infected broilers in the flocks, that the introduction occurred when catching the first batch, and that campylobacter spreads through the entire flock within a week.

SIGNIFICANCE AND IMPACT OF THE STUDY:

The results from this study emphasize the need to manage depopulation of broiler houses as quickly as possible and in one batch only.
