The NFU advised farmers to support their JAB campaign, which aims to get all cattle and sheep vaccinated against the bluetongue, which is caused by a virus spread by certain types of biting midges.
The board will be responsible for dealing with exotic disease outbreaks such as bluetongue, policy on endemic diseases such as bovine TB, advising on the payment rates for animals culled as part of disease control and controlling animal diseases which pose a threat to public health.
Proposed for introduction in 2012, farmers will be forced to pay an annual fee to help pay for surveillance and preparation for the outbreak of diseases, such as bluetongue, classical swine fever and foot-and-mouth.
A better vaccination strategy in Europe has reduced the risk of diseases spreading to the UK; demonstrating again that our best defence against exotic diseases such as bluetongue and F&M is to control them better elsewhere.
"The problem is that the life cycles of diseases such as bluetongue speed up as temperatures go up," said Dr Chris Oura, of the Institute for Animal Health in Newbury.
Given the dangers posed by conditions such as bluetongue, pasteurella and clostridia, the benefits of vaccination are clear.
HD is caused by two closely related viruses, epizootic hemorrhagic disease (EHD) or bluetongue virus.
There are 2 subtypes of EHD virus and 5 subtypes of bluetongue in North America.

With a full-scale foot and mouth disease outbreak under way in Surrey and east Berkshire, the arrival of another scourge for farmers to deal with and be prostrated by, with the news that a single animal infected by bluetongue has been detected in Suffolk (near Ipswich) and will soon be culled, farmers and others could be forgiven for thinking that pestilence on a somewhat Biblical scale was being visited upon us for some reason.
