Pneumonia in pig fattening

One of the most common germs leading to diseases of the lung in pigs, is Actinobacillus pleuropneumonie (APP). This germ is widely spread in the world and can mainly be found in countries with intensive pig breeding and fattening.

APP is transmitted via air as well as through direct contact. Infection in animals happens by droplet infection. An Infection is advantaged by housing with grids, changing coves and tracks for excrements as well as by frequent change of location of the animals within the breeding period.

‘Infection with occurs in every age; however, mainly affected are pigs aged between 2nd and 6th month. Most notably, economic losses occur in mast farms. Symptoms range from aching cough, breathing through the mouth, loss of appetite, high fever to impaired behaviour in general. Economic losses are caused by higher costs for feeding, because the animals can´t use the feed anymore as effective as before; breeding therefore is prolonged and medical therapy produces high costs.

The animals lose a lot of weight and grow slower. Their bristles are dull and matt. Opening the chest, adhesions between lung and chest wall stand out. Mostly, in the pulmonary tissue one can find some lumps, filled with matter and of different sizes. The affected areas of the lung seem to be compact and heavy and are coloured dark red.

Combatting is rather difficult, because APP rarely occurs separately on the farm; usually it comes along with another virus/germ, which hardens therapy and increases costs.
