Pre-weaning supplementary feed and porcine post-weaning diarrhoea
Hampson, D.J., Fu, Z.F. and Smith, W.C. (1988) Pre-weaning supplementary feed and porcine post-weaning diarrhoea. Research in Veterinary Science, 44 (3). pp. 309-314.
Attempts were made to induce an intestinal hypersensitivity response to weaner diet by feeding pigs with small quantities of this material before weaning. In two trials using different weaner diets piglets subjected to this regimen showed no significant differences in small intestinal structure, in ability to absorb xylose, in bodyweight gain, in incidence of diarrhoea or excretion of enteropathogens after weaning compared with pigs not given any of the diet before weaning, or fed with a different diet before weaning. When post-weaning diarrhoea occurred it was associated with an earlier, more prolonged and greater proliferation of enterotoxigenic Escherichia coli in the small intestines than occurred in healthy pigs after weaning. The greater proliferation in pigs which developed diarrhoea could not be attributed either to an excessive dietary intake after weaning, or to a specific proliferation of rotaviruses.
