Clinical case of the world

We concluded an Edema disease episode, which is extremely unusual at this age.

Carcasses showed a good body condition and a pronounced cyanosis in the area of the ventral abdomen and the ventral throat.

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.

We are called because of sudden deaths in several integrated fattening farms.

In May 2013 a sow farm in Indiana (USA) broke with PEDv. In mid March 2014, scour were observed in the onsite nursery and finisher. In the subsequent week, PEDv was diagnosed of the same strain (99.9 % homology) and the virus moved into the farrowing house.

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.

Fertility problems with variable reproductive performances were detected. Also, ear and tail necroses appear in nurseries, and continuous diarrhoea cases and rectal prolapses in the fattenings.

In the last 4 batches of weaned piglets, the farmer saw around 3% of anorexic and lethargic piglets. All the treatments he tried failed (amoxicillin or florfenicol injections), and finally the piglets died.
