    Abstract:
    This investigation compared the effect of diets with increasing content of insoluble dietary fibre (DF) on the establishment and persistence of Oesophagostomum dentatum in growing pigs. Twenty-eight worm-free pigs, from a specific pathogen-free farm were randomly divided to four groups of seven animals. The animals were assigned to the following diets: diet A, barley flour plus protein mixture (70%:30%); diet B, barley flour, oat husk meal plus protein mixture (65%:7%:28%); diet C, barley flour, oat husk meal plus protein mixture (60%:14%:26%) and diet D, barley flour, oat husk meal plus protein mixture (55%:21%:24%). The diets were formulated to provide increasing content of DF but constant levels of digestible protein per feeding unit for pigs. All pigs were experimentally inoculated with 6,000 infective O. dentatum larvae and followed coprologically for 11 weeks post infection, whereafter they were slaughtered. The experimental diets influenced the mean transit time and the metabolism in the large intestine significantly. Diets C and D, with highest content of insoluble DF, provided favourable conditions for establishment of O. dentatum, but diets A and B led to a significant lower worm numbers and fecundity.
