Abstract:

The level of resistance and productivity were determined by animal’s immunity. Chinese herbal medicine show unique advantages on the aspect of immunological enhancement, and they can enhance the level of specific or non-specific immunity in animals. In this experiment the antibody titers and the exponent of immune organ were monitored by feeding different doses of “Yupingfeng”(1ml/L,2ml/L,4ml/L) on ND vaccine immunnized chicklings in each group consecutively. The result indicated that the level of ND antibody and the exponent of immune organ were enhanced. The effect in the middle group(2ml/L) was better than the others. The results showed that “Yupingfeng”could enhance humoral immunity and cellular immune function of chicklings.
