Changes in the growth, humoral and mucosal immune responses following β-glucan and vitamin C administration in red sea bream, Pagrus major

A combination of β-glucan and vitamin C presented an additive effect on inducing the growth, immune responses and oxidative status of red sea bream. We recommend that treatment of 500 mg of β-glucan and 400 mg of vitamin C per kg diet is the appropriate concentration of inducing the red sea bream immune response.
