The adhesion of Escherichia (E.) coli K88ac to epithelial cells of the small intestine was studied after slaughter in 564 crossbred pigs (Swedish Landrace x Swedish Yorkshire). E.coli K88ac adhered to epithelial cells obtained from different parts of the small intestine in 40·8% of the pigs studied. Performance data indicated that presence of the receptor resulted in poorer daily gain during the 1st weeks of life, but that it had a beneficial influence on daily lean growth during the fattening period (24 to 100 kg live weight).
