TI  - Ascaridia galli infection of pullets and intestinal viscosity: consequences for 
      nutrient retention and gut morphology.

AB  - 1. Pullets were given a control diet or a diet supplemented with a 
      non-starch-polysaccharide hydrolysing enzyme preparation (NSP-enzyme) from weeks 
      6 to 14 of age to induce differences in the viscosity of the small intestinal 
      ingesta. Half of each feeding group (n = 25) was infected with 250 embryonated 
      Ascaridia galli eggs at an age of 6 weeks. 2. At 14 weeks of age, before the 
      pullets were slaughtered, a balance experiment was conducted, to sample ingesta 
      for viscosity measurements. Also, tissue samples of jejunum and ileum were taken 
      for morphometrical and histopathological studies. 3. An infection of pullets with 
      A. galli reduced the viscosity of the jejunal ingesta at high initial levels of 
      viscosity after feeding the NSP-enzyme unsupplemented diet. 4. The faecal A. 
      galli egg output by the pullets expressed as eggs per g excrement (EpG) was 
      significantly reduced in infected pullets given the NSP-enzyme supplemented diet. 
      Also, the number and length of worms was less in these pullets. 5. The tunica 
      muscularis of the jejunum was significantly thickened, this effect being more 
      pronounced at a low intestinal viscosity. 6. NSP-enzyme addition resulted in an 
      increased length of jejunal villus and was paralleled by a decrease in jejunal 
      viscosity. 7. Histopathology of jejunal and ileal sections revealed no 
      pathological alterations. 8. The apparent retention of organic matter was 
      increased after enzyme addition while parasite infection exerted no effect.
