Abstract

 

Two-month-old piglets were fed with 1, 1.5 and 2% immune synergist of Chinese medicinal herbs together with vaccination against classic swine fever. Serum IgG and IgM levels increased more than the control group on day 30 (P<0.05). B and T lymphocyte proliferation in piglets fed with 1.5 and 2% herbal immune synergist markedly increased on day 30 as compared to the control group (P<0.05). Improvement was also observed in T lymphocyte CD3+, CD4+, CD8+ and CD3+/CD8+levels. Meanwhile, there were significant differences in SOD activities and rate of neutrophil phagocytosis between synergist groups and the control group. These results suggest that herbal immune synergist of Chinese traditional herbs prescription enhances the protective effect of classic swine fever vaccine.

 

Key words: Immune synergist, Chinese medicinal herbs, classic swine fever vaccine.
