摘　　要：试验旨在研究饲粮中添加人参多糖(ginseng polysaccharide,GPS)对哺乳母兔生产性能及哺乳仔兔免疫性能的影响。选取36只妊娠10 d左右、遗传背景相近的种母兔随机分为3个处理,每个处理12只母兔。预试期7 d后,3个处理组分别饲喂添加0(对照组)、150 mg/kg(T150组)、300 mg/kg(T300组)GPS的饲粮,正试期34 d。结果表明:①T150和T300两个处理组种母兔初乳中IgA含量较对照组显著提高(P<0.05)。②T150和T300两个处理组仔兔出生第0 d血清白细胞介素-2(IL-2)含量显著高于对照组(P<0.05),T300处理组仔兔出生第7 d血清IL-2含量较对照组显著升高(P<0.05)。③T150和T300两个处理组仔兔出生第0、7、14 d平均重量和成活数较对照组显著增加(P<0.05)。饲粮中添加GPS可提高泌乳母兔的生产性能和哺乳仔兔的免疫性能。The effects of dietary supplementation of ginseng polysaccharide(GPS)on production perfor⁃mance of lactating rabbits and immunocompe⁃tence of lactating rabbits were investigated.In the experiment,36 female rabbits with pregnancy about 10 d and similar genetic background were randomly divided into three treatments,12 for each treatment.After a pre-feeding period of 7 d,the three treatment groups were fed with diets supplemented with 0(the control group),150 mg/kg(T150 group),and 300 mg/kg(T300 group),respective⁃ly,for a total of 34 d.The results showed that①The IgA content in colostrum of female rabbits treated with T150 and T300 was significantly higher than that in the control group(P<0.05).②The serum IL-2 levels on the 0th day of birth of rabbits in the T150 and T300 treatment groups were significantly higher than those in the control group(P<0.05).The serum IL-2 level on the 7th day of birth of rabbits in the T300 treatment group was significantly higher than that in the control group(P<0.05).③Compared with the control group,the average weights and survival numbers of the neonatal rabbits in the T150 and T300 treatment groups on the 0,7 and 14 days of life were significantly increased(P<0.05).The addi⁃tion of GPS in diet could improve the production performance of lactating rabbits and the immune perfor⁃mance of suckling rabbits.
