The following conditions were highlighted in the SAC VS monthly report for June 2007 and, given similar conditions in 2008, could well be important this year.
Cattle
- Parasitic disease, particularly coccidiosis in spring born suckled calves, early cases of lungworm and acute liver fluke cases.
- Malignant catarrhal fever cases which, given the similarities of clinical presentation to bluetongue, could present diagnostic problems.
- Pasteurella pneumonia in calves at grass.
Sheep
- Ill thrift associated with cobalt deficiency in lambs at grass.
- Nematodiriasis, depending on climatic conditions.
Game birds
- Coccidiosis, rotavirus infections and spironucleosis (hexamitosis) in young birds.
GENERAL INTRODUCTION
Above average rainfall and hours of sunshine were features of the weather in Scotland in April. The mean temperature of 5.7 degrees Celsius for the month was close to average but there were wide fluctuations from a high daytime temperature of 19.1 degrees Celsius in Aberdeenshire to 12 consecutive nights of air frost in Dumfriesshire. The Scottish Government announced that 12 million doses of bluetongue vaccine will be ordered for use in a compulsory vaccination programme of sheep and cattle this winter. Half of the cost of the vaccine will be met by the Government and a system of monitoring for non-compliance will be put in place.
The Scottish Agricultural Science Agency (SASA) reported a 10 year high in incidents of suspected animal poisonings. One hundred and ninety such incidents were investigated, including more than 50 involving birds of prey.
