摘要
[ Objective] To study the effects of Lanerkang-A on the immunity and growth performance of piglets and lay a base for the development of green medicine on immunity stimulator, [ Method] A total of 50 healthy piglets were randomly divided into two groups, the control group （Group 1 ） and the test group （Group 2）, 25 piglets in each group. All the piglets were intramuscularly injected with 2 ml porcine reproductive and respiratory syndrome （PRRS） propolis inactivated vaccine at 25 days old. The piglets in the Group 2 were fed with feed containing Lanerkang-A （ 10 ml/kg） at 42 days old. After 7-d feeding, the antibody titer against PRRSV and the cytoimmunity were detected using ELISA and E-rosette, respectively. [ Result] Lanerkang-A increased antibody titer against PRRSV by 4 titers and increased E-rosette forming rate by 7%. The average daily weight gain increased by 15.68%. [ Conclusion] Lanerkang-A can greatly enhance the immunological function of body, increase the daily gain of piglets, as well as improve their growth performance.
