摘要
为研究黄芪多糖稀释液对猪瘟活疫苗的免疫增强作用,将60头断奶仔猪随机分成2组(对照组和黄芪多糖组),对照组和黄芪多糖组分别接种灭菌生理盐水和黄芪多糖稀释液稀释的猪瘟疫苗。结果显示,在疫苗免疫后7、14、21和28d,黄芪多糖组的猪瘟抗体效价(log2)较对照组分别提高5.3%(P>0.05)、9.8%(P<0.05)、14.0%(P<0.05)、14.2%(P<0.05)。表明利用黄芪多糖稀释液稀释猪瘟疫苗可显著提高猪瘟疫苗免疫后的抗体水平,增强猪瘟疫苗的免疫效果。
To study the immune enhancement effects of Astragalus Polysaccharides dilution on swine fever vac-cine, 60 weaned piglets were randomly divided into 2 groups （control group and astragalus polysaccharide group）,control group and astragalus polysaccharide group were respectively inoculated with sterile saline and astragaluspolysaccharide dilution of swine fever vaccine. Results showed that in 7th, 14th, 21st, 28th day after vaccination,swine fever antibody titer （log2）of Astragalus polysaccharide group were respectively increased by 5.3%（P〉0.05）,9.8%（P〈0.05）, 14%（P〈0.05） and 14.2%（P〈0.05）, compared with the control group. The results showed that theswine fever vaccine with astragalus polysaccharide diluent can significantly improve the antibody level after swinefever vaccine immunization, and enhance the immune efficacy of classical swine fever vaccine.
