Chronic, Acute or Sub-clinical


PIA (Porcine Intestinal Adenomatosis) or PPE (Porcine Proliferative Enteritis), also known under the names Garden-hose Gut, Proliferative Haemorrhagic Enteritis (PHE), Necrotic Enteritis (NE) or Ileitis, is still one of the most common diseases in fattening pigs worldwide and causes serious economic losses.

PIA is an enteric disease which causes inflammation and a typical hyperplasia of epithelial cells (adenomatosis) at the transition of the ileum to the large intestine. This hinders the passage of digesta and impairs digestion and growth performance. PIA is caused by Lawsonia intracellularis and the fact that this bacterium is located ìnside the epithelial cells, makes it quite difficult to treat.   

The severe acute form (Proliferative Haemorrhagic Enteritis; PHE) is most common in market weight fattening pigs and rearing gilts, and is characterised by pale animals and acute mortality and bloody/black diarrhoea. In starters and growers (<70 kg) the chronic or necrotic form occurs more frequently, characterised by gradual wasting and chronic diarrhoea. This form causes the greatest economic damage. PIA may also occur in weaners and in sow herds. 

The purchase of rearing gilts and starters, hygiene, prevention of stress and support of immunity are amongst the most important factors to treat this difficult disease. Regarding feed, ingredient selection and the use of specific feed additives should receive special attention. Today Framelco is able to contribute to the treatment with specific blends of patented α-monoglycerides, which are known for their strong antimicrobial and antiviral properties.
