It is one of the most common diseases in young piglets: diarrhoea. Diarrhea is the result of a digestive disorder. It can have several causes, including incorrect nutrition (moderate quality, incorrect temperature), overfeeding or abrupt feed changes. But often diarrhea is caused by a virus, bacteria or parasite. Examples include E-coli, Rota and Coronavirus, Cryptosporidia, Coccidiosis and Salmonella (see table 1).
Table 1: Overview of a number of pathogens that cause diarrhea in piglets (Veterinarian, 2020).
|E. Coli (geboortediarree)||From day 1 to day 5 after birth||Watery diarrhea (sometimes yellowish). High mortality|
|Clostridium Perfringens type C||From a few days after birth||Severe diarrhea, sometimes with blood. High mortality|
|Clostridium Perfringens type A||From a few days after birth||Watery or pasty diarrhea, without blood|
|Virus (Corona)||Can occur both before and after weaning||Watery diarrhea (greenish-yellowish). Very high mortality|
|Virus (Rota)||Can occur both before and after weaning||Watery diarrhea|
|Coccidiosis||From day 10-14||Water-thin diarrhea (grey-green-whitish), can smell like soured milk|
In all cases, the piglet loses a lot of fluid, electrolytes and energy. All this results in the piglet drying out, losing weight and growing retarded. In case of severe diarrhoea, the piglet can die. It is therefore extremely important to act quickly and appropriately for diarrhea in piglets.
