Treatment

In an acute outbreak examine the at-risk group three times daily to identify disease as early as possible. It may be necessary to inject the whole group. The decision to inject is a balance between effect, and risk of more disease due to the stress of handling the pigs.

As affected pigs stop eating or drinking water or feed medication is usually ineffective. App usually has a wide range of antibiotic sensitivity. On the first day inject the pig twice eight hours apart. The following antibiotics are usually effective:

  • Amoxycillin.
  • Ampicillin.
  • Ceftiofur. This is a very rapid acting medicine and gives a good response.
  • Enrofloxacin.
  • Tiamulin, OTC, LA. This can be used in more chronic cases. Repeat every two days.
  • Penicillin.
  • Penicillin/streptomycin.
