H. Nollet et al., Protection of just weaned pigs against infection with F18(+) Escherichia coli by non-immune plasma powder, VET MICROB, 65(1), 1999, pp. 37-45
The anti-colonization effect of porcine plasma powder against experimentall
y induced postweaning diarrhoea and oedema disease in just weaned piglets w
as examined. Piglets were infected with an Escherichia coli strain expressi
ng F18ac fimbriae and producing SLTIIv- and LT-toxins. Reduced fecal excret
ion of the challenge strain and protection against clinical symptoms was ob
tained by daily supplementation of the feed with either 90 or 45 g of plasm
a powder. However, the piglets receiving 90 g of plasma powder a day showed
diarrhoea and reduced weight gain compared to the piglets receiving 45 g o
f plasma powder a day. The diarrhoea was attributed to biogenic amines rele
ased from excessive protein in the diet. (C) 1999 Elsevier Science B.V. All
