Beware pneumonia

Beware pneumonia

MUGGY wet weather is causing pneumonia in housed stock across the country, says vet Tony Andrews.

"All regions have seen quite bad outbreaks." At the first sign of the disease contact your vet and establish what is triggering the outbreak to prevent further cases.

"Often, the main causes are poor ventilation, damp, overcrowding, not enough bedding and mixing cattle of different ages. Dampness and poor ventilation let bugs survive and spread between animals through aerosol and grooming.

"In the right conditions bugs will live for 15-30 minutes. So where an animal is infected separate it from the rest of the group to help it recover and provide it with undisturbed access to feed."

An early diagnosis as to what strain of pneumonia it is can allow effective vaccination in face of an outbreak, he advises.

Pfizer Animal Health says vaccination before housing may be cost effective. A recent company study shows the hidden costs from calf-pneumonia amount to £143.50 in reduced growth rates, which is 61% of the total costs of the outbreak.

But in some cases antibiotics will be needed to treat sick animals. Elanco Animal Health says using more expensive antibiotics will result in an 8-10% lower death rate and higher daily liveweight gains compared with oxytetracycline products. &#42

LIVESTOCK producers are being warned that recent fluctuations in temperatures and still, humid conditions are ideal for pneumonia.

Risks are exacerbated if animals are overcrowded, says Tony Andrews of the Royal Vet College.

"Ventilation must be good, even though buildings may appear cold," he says. Stress such as changes in feeding should also be avoided.

He warns that pneumonia cases should be diagnosed and treated quickly. "Do not wait until all animals are showing signs of disease."

Viral and pasteurella vaccines for cattle and sheep could help control pneumonia, but pasteurella pneumonia incidence is also stress related, adds Dr Andrews.

For pigs, the pleuropneumonia vaccines are good if this is the cause of disease, and he claims enzootic pneumonia in pigs has decreased since a vaccine for it has been available. &#42
