枸杞多糖对泌乳母兔生产性能及血清生化指标的影响

Effect of Lycium Barbarum Polysaccharide on Production Performance and Serum Biochemical Indexes in Lactating Rabbit

【目的】研究日粮中添加枸杞多糖对泌乳母兔生产性能及血清生化指标的影响,为枸杞多糖在家兔日粮中的应用提供理论依据。【方法】选择同期分娩的48只泌乳獭兔,按照胎次、产仔数、体重相近的原则,随机分成4组,每组12只,每组仔兔总数相等(72只)。Ⅰ组为对照组,饲喂基础日粮,Ⅱ、Ⅲ、Ⅳ组在饲喂基础日粮的基础上分别添加0.5%、0.75%、1%的枸杞多糖,试验期共30 d。【结果】添加0.5%、0.75%和1%枸杞多糖组的仔兔35日龄断奶窝增重分别比对照组提高了5.95%、4.60%和6.47%,但差异均不显著(P>0.05);各试验组仔兔的断奶成活率与对照组相比均差异极显著(P<0.01);各试验组母兔的泌乳力与对照组无显著差异(P>0.05);各试验组母兔和同窝仔兔的平均日采食量与对照组相比差异均不显著(P>0.05);添加0.5%、0.75%和1%枸杞多糖组的母兔泌乳35 d后的体重失重分别比对照组低20.9%、16.2%和15.5%,但差异均不显著(P>0.05)。添加0.5%、0.75%和1%枸杞多糖组母兔血清LDH含量分别比对照组降低了32.6%(P<0.01)、19.8%(P<0.05)和48.3%(P<0.01);其余检测指标在各试验组母兔血清中的含量与对照组相比有不同程度的降低或升高,但均差异不显著(P>0.05)。【结论】在泌乳母兔日粮中添加枸杞多糖可以不同程度地提高仔兔断奶成活率、促进仔兔的生长发育、降低母兔在泌乳期的失重,且对血清生化指标无不良影响。

【Objective】This study was performed to investigate the effects of lycium barbarum polysaccharide（LBP） on production performance and serum biochemical indexes in lactating rabbit.【Method】A total of 48 lactating rabbits in the same period of parturition were selected and randomly divided into 4 groups for 1-monthtrial.GroupⅠ was used as a control group and the rabbits were fed with basal diet.Group Ⅱ,Ⅲ,and Ⅳ were used as experimental groups and the rabbits were fed with basal diet plus 0.5%,0.75%,and 1% LBP.【Result】The results showed that compared to the control group,35-day-old weaned rabbit weight gain of experimental groups Ⅱ,Ⅲ,and Ⅳ increased by 5.95%,4.60% and 6.47%,respectively（P0.05）.The weaning survival rate of experimental groups Ⅱ,Ⅲ,and Ⅳ was significantly improved（P0.01）.The female rabbit lactating capacity and average daily feed take of experimental groups Ⅱ,Ⅲ,and Ⅳ were not different significantly（P0.05）.The lactating rabbit weight loss of experimental groups Ⅱ,Ⅲ,and Ⅳ decreased by 20.9%,16.2% and 15.5%,respectively（P0.05）.The level of LDH in experimental groups Ⅱ,Ⅲ,and Ⅳ was,respectively,decreased by 32.6%（P0.01）,19.8%（P0.05） and 48.3%（P0.01）.The level of the other serum biochemical indexes in experimental groups Ⅱ,Ⅲ,and Ⅳwas not different significantly（P0.05）.【Conclusion】It was concluded that adding appropriate LBP in lactating rabbit diet could improve newborn rabbits weaning survival rate,promote newborn rabbits growth,reduce lactating rabbit weight loss,and no adverse effects on serum biochemical indexes.
