Dietary Fish Meal Level and a Package of Choline, β-Glucan, and Nucleotides Modulate Gut Function, Microbiota, and Health in Atlantic Salmon (Salmo salar, L.)

Table 9

Results of an ordinal logistic regression of the impact of supplementation and fishmeal level on the distribution of the histological scores among the diet groups for a given morphological feature in each of the different intestinal segments and liver. Numbers of cells are values.
