Highlights

  • SUMMARY OF HIGHLY PATHOGENIC AVIAN INFLUENZA OUTBREAK

  • BIG LIVER AND SPLEEN SYNDROME: RECENT DEVELOPMENTS

Overview

The importance of veterinary scanning surveillance was well illustrated during the quarter with the detection of Low Pathogenicity Avian Influenza H7N2 in a small poultry flock in North Wales in May, as described on pages 4 and 5 of this report.

Some of the economic consequences of the outbreak of highly pathogenic Avian Influenza H5N1 in turkeys in February can be seen in the statistics on page 2 of this report; in particular there was a drop in monthly turkey slaughterings compared with 2006 of between 22.1 and 27.2% between February and June. This is against a backdrop of a continued decline in UK turkey poult placings. At the same time the pressure on chicken margins is being affected by a continued increase in wheat and other cereal prices resulting in year-on-year poultry feed price increases of up to 13%

In recent months there has been emerging interest in Big Liver and Spleen disease in chickens, and this report describes the findings of a serological survey of the disease, confirming the presence of antibodies in UK flocks.

As described in the virology report, rotavirus has been confirmed in several submissions of young pheasants and partridges during the quarter, and submissions have been ongoing through July. Mortality in young gamebirds resulting from this disease has been compounded by the effects of the adverse weather conditions in June and July, and considerable losses have been recorded on some rearing fields.
