However, high dietary levels of soy induce pathological changes in the hindgut of salmonids. This may also be problematic with other plant materials. The content of nutrients, structural compounds, and antinutritional factors (ANFs) vary among different soy products, and among different soy cultivars and crops. Thus, soy of different origin should impact the intestinal function in salmon differently. This study will characterise and profile soy (and other plant) products of different origin in terms of composition and ANFs, and grade how they affect growth and digestive function, induce pathology in the intestine, and change the gut microflora in Atlantic salmon. We will measure growth and digestibility of nutrient, enzyme activities in intestinal contents and tissues, bile salts in intestinal contents, pathology in the gastrointestinal tract (GIT), systemic and GIT immunologial responses, rate of tissue regeneration (cell division) in the GIT, and changes in both the adherent and luminal intestinal microflora. Pathology and immunological responses of the GIT will be evaluated histologically and by histochemical colouring techniques. Cell division GIT tissue will be indicated by staining the proliferating cell nuclear antigen (PCNA) and quantified by image analysis. The definition soy and other plant proteins with low negative impact on the intestine will ameliorate negative effect associated with plant proteins in salmon feed. It will also increase the general understanding about effects of different vegetable components in salmon. This will reduce the dependence on marine feed ingredients and will contribute to increased profitability in the salmon industry.
