With regard to the young stock, diagnosing the exact cause
of pneumonia is rarely simple, but always important. Knowing what you are up
against is the key to working out the best preventative programme.
Older animals with a high
temperature (up to 107OF) and noisy breathing could be suffering
from the IBR virus. In such cases, there is discharge from the nose and
sometimes the eyes as well. IBR and the other main viruses, RSV and PI3, often
make a calf ill and off its food. A young animal with a temperature of between
103-105OF and sounding asthmatic, however, might be infected with
RSV.
Vets can blood test calves
to identify possible causes of pneumonia on your farm, then work out a suitable
vaccination and management programme to prevent disease and losses. Vaccinated
calves can mount a fast powerful defence when challenged with pneumonia. The
vaccine BovilisŪ Bovipast RSP uniquely protects against both viral and
bacterial causes of pneumonia. BovilisŪ IBR Marker Live meanwhile reduces
clinical signs and virus shedding.
Most cases of pneumonia are
due to a mixed infection made up of viruses and bacteria. By the time animals
are coughing and ill with pneumonia their rate of DLWG will be significantly
decreased and units that expect a pneumonia problem most seasons, would do well
to consider vaccination to assist in preventing this.Whatever the cause, once calves are visibly
coughing they will already be suffering lung damage which will need prompt and
aggressive therapy with antibiotics and anti-inflammatories.
Please ring and speak to one of the vets to discuss pneumonia prevention and treatment.
