State of antioxidant and immune systems in fox and polar fox in postvaccinal period during addition of succinic acid to their food

In scientific-practical experiment in young foxes and polar foxes during planned vaccination at the beginning of postvaccinal period the authors revealed the rise in content of antibodies, globulins, bacterial activity of blood serum and phagocytosis activity with simultaneous reduction of activity of protein SH-groups and ceruloplasmin. After forming of immune response the activity of protein SH-groups and ceruloplasmin is restored. The succinic acid after addition to food (5 mg/kg live weight) before and after planned vaccination promotes to the enhancement of immune response and more rapid recovery of activity of protein SH-groups and ceruloplasmin at the postveccinal period. For this purpose the succinic acid is recommended to introduce in rations of foxes and polar foxes during 5 days before vaccination.
