Overview

In terms of disease, 2007 has been dominated by the outbreaks of Highly Pathogenic H5N1 Avian Influenza in turkeys in February and November. These are reviewed in an international context on pages (4) and (5) of this report. At the time of writing ten cases have also been identified in mute swans in Dorset (page 4).

Increasing feed prices have had a major impact on the poultry sector through the year.

As a result of this and other increasing costs, many producers face uncertainty as to what the future will hold for the industry. This is shown in the statistics on page 2 in the slight decline in broiler chick placings and broiler slaughterings in the fourth quarter compared to last year. However layer chick placings have been relatively buoyant through the Amongst the endemic diseases covered in this report, a report of a possible new medication for blackhead (histomonosis) in turkeys is described on page 14, the continuing decline in diagnoses of necrotic enteritis in broilers on pages 15 and 16 and the increasing trend in motile protozoal disease in gamebirds on pages 17 and 18. Virus surveillance isolates of note during year.

2007 include further isolates of avirulent Newcastle disease virus, the first UK isolate of the QX strain of Infectious Bronchitis virus and the confirmation of Avian Encephalomyelitis virus infection in pheasants by PCR testing and serology.

Duck hepatitis type 1 virus was isolated with avian influenza H3N8 from ducklings (pages 12 -13). A serological survey reported in the April-June report confirmed that Big Liver and Spleen Disease virus is present in the UK.
