Digestive processes have a great impact on the pig sector, both in terms of mortality in piglets and the associated slow growth and heterogeneity of the flocks.
However, identifying the cause of a digestive pathology can be complicated:
The clinical signs and history of the farm may point to a presumptive diagnosis, but this will always need to be confirmed by laboratory analysis.
There are multiple factors that may trigger a diarrheal process, and more than one etiological agent may be involved.
Some diarrhea-producing agents, such as E. coli or C. perfringens, are part of the digestive flora, but isolation of these bacteria does not mean that they are the cause of diarrhea.
Discovering the real origin of a digestive process in a pig farm requires an organized and methodical approach that includes the a differential diagnosis based on the clinical picture, so that laboratory analyses can be directed towards the detection of specific pathogens.
Differential diagnosis of digestive diseases in pigs
Establishing a differential diagnosis based on the age of the animals and the symptoms they show is the first step in deciding which samples will be taken to the laboratory and how they will be analyzed.
The importance of adequate sampling
The success of the diagnosis depends on the choice of the samples, as they must be representative and in good condition.
How many animals?
With 4-5 animals from different litters, a good representation of the farm is obtained.
Digestive packages: they allow a complete analysis, including histopathological study.
