Great care is needed particularly when handling young pigs above 6kg/3 weeks of age, to avoid causing lasting damage.
Captive bolt humane stunners do not kill larger growing pigs or adults, they render the pig unconscious. Further action is needed to ensure the pig is dead.
This case study describes an outbreak in a commercial unit which proved difficult to stop without vaccine. Since 2014 an increasing number of cases of this disease have been reported in Europe though it remains unclear why it has reappeared.
It has not proved possible to actively eliminate App from chronically affected permanently occupied breeder-feeder herds.
This paper describes the acute outbreak of App within a pig population and how control may be achieved.
At least 25% of the pigs from 2 to 3 weeks old were reported to be lame, some so severe that they lay in the arcs shaking and unable to stand.
This clinical case study tracks the long term pattern and control of Actinobacillus pleuropneumoniae (App) disease in a breeder feeder farm through the 1990’s.
Well intentioned treatment of piglets at birth may adversely affect the normal early nasopharyngeal or tonsil colonisation making pigs vulnerable to respiratory infections due to potential pathogens present within the herd.
