Warning over rise in blackleg cases
Vaccination is the best approach as antibiotic treatment is unlikely to be effective unless it is begun in the very early stages.
Vaccination is the best approach, AHDB says

Farmers are being warned about a rise in cases of the clostridial disease blackleg.

The disease was the second most common diagnosis made when post-mortems were carried out on growing cattle at Farm Post Mortems Ltd between June and August 2017. The rise continued to be seen throughout September and October.

Blackleg is most commonly caused by the bacteria Clostridium chauvoei, which is generally found in soil and cattle faeces. Similar lesions are less commonly caused by Clostridium septicum or Clostridium novyi.

Young growing animals (six to 12 months) are most often affected, with cases increasing when animals are turned out.

Vaccination is the best approach as antibiotic treatment is unlikely to be effective unless it is begun in the very early stages, according to AHDB Beef & Lamb.

There is a vaccine available that covers just blackleg alone, or multivalent clostridial vaccines that also offer protection against the disease. Several clostridial vaccines are broad spectrum and prevent other important diseases such as black disease, clostridial abomasitis and disease caused by Clostridium perfringens.

Animals should be vaccinated from three months of age onwards. Two injections are required three to four weeks apart. Immunisation must be completed two or three weeks before the period of risk, which will vary depending on the date of turnout.

A yearly booster of a single injection should be given two to three weeks before the period of risk, and the interval for boosters should be no more than 12 months.

Farmers are advised to speak to their veterinary surgeon for advice.

Amur leopard cubs caught on camera

News Story 1
 A pair of Amur leopards have been captured on camera for the first time since their birth. The Royal Zoological Society of Scotland announced the birth in July, but with human presence being kept to a minimum, it was not known how many cubs had been born.

Motion sensitive cameras have now revealed that two cubs emerged from the den - at least one of which may be released into the wild in Russia within the next two or three years. The Amur leopard habitat is not open to the public, to help ensure the cubs retain their wild instincts and behaviour. Image © RZSS
