Immunomodulation by dietary vitamin C and glucan in rainbow trout (Oncorhynchus mykiss)

The aim of this study was to determine the influence of dietary glucan and vitamin C, alone and in combination, on the cellular and humoral immune responses of rainbow trout. After 4 weeks of adaptation on a control diet containing glucan at 0 ppm and vitamin C at 150 ppm, four groups of rainbow trout were fed the experimental diets containing vitamin C at 150 and 1000 ppm plus a fixed amount of glucan, or no glucan for 2 weeks. The fish were...
