In a factory farm located in Mexico an increase in the mortality in the farrowing quarters was seen, and this coincides with temperature and relative humidity increases.

The losses due to diarrhoea problems appear concentrated, basically, during the first week in the weaners stage, whilst in the farms that have not suffered diarrhoea problems, the mortality is distibuted more evenly.

We analyze a real case, and we will check out how a partial analysis of the data can give place to erroneous conclusions.

The pig farm management team in charge of the post-weaned piglet nursery areas on these wean-to-finish sites has found serious problems with diarrhoea in recent batches of piglets arriving from the breeding farms.

Two species of Brachyspira are well-recognized pathogens of pigs: B pilosicoli and B. hyodysenteriae. Recently, dysentery-like disease has been reported in association with infection by strongly beta-hemolytic spirochetes which are not identified as B. hyodysenteriae.

Patterns of association are quite helpful in helping focus resources whether that is time, money, or any intervention we are seeking to implement.

Approximately 15-20 days after entering the growth phase, generalized coughing and weight loss were noted. The morbidity rate was almost 30% and the mortality rate was 4-6 %.

Here we present a table of differential diagnosis of the most common diarrheas during lactation.

Rotaviruses are important enteric pathogens that affect newborns of several animal species. In swine, they can cause gastroenteritis in piglets.

Although pigs can be infected with different species of coccidia, in suckling piglets the most important disease caused by enteric protozoa is coccidiosis due to Isospora suis.

The genus Clostridium includes numerous species of anerobic bacteria with large rod-shaped forms, spore makers, and producers of extremely potent and diverse toxins that are almost always responsible for the diseases they cause.

Escherichia coli is an enterobacteria that forms part of the normal intestinal microbiota of healthy animals. Usually, E. coli present in animals are communal antipathogenic strains and they even play a beneficial role, since they compete in several ways with the pathogenic strains in the ecological niche of the lumen.

The establishment of normal gut microbial communities can also prevent the colonization of pathogenic microorganisms.

The supply of wet feed, when compared to dry feed, improves the rate of growth and conversion, at least these are the results of the trials carried out in the experimental stations.

In order to apply the most suitable feeding regime to newly weaned pigs it is important to balance the trade off between the detrimental effect on performance of feeding levels of protein that are too low to allow maximal growth and those which increase the risk of post weaning diarrhoea.

The AMPs (also called host defence peptides) are small gene encoded peptides of 1 to 5 kDa that have a broad range of activity against gram-positive and gram-negative bacteria, fungi and mycobacteria
