摘要: 本试验旨在探讨黄芪多糖(Astragalus polysaccharides,APS)对泌乳期奶牛血清生化指标的影响。选用年龄、胎次和体重相近的健康荷斯坦奶牛40头,采用单因子完全随机试验设计,随机分为4组,每组10头奶牛,Ⅰ组为空白对照组,饲喂不含APS的基础日粮;Ⅱ~Ⅳ组分别饲喂添加10、50和100 g/(头·d)APS的基础日粮,试验期20 d。结果表明,随着APS添加剂量增加,Ⅱ、Ⅲ、Ⅳ组血清中丙氨酸氨基转移酶(ALT)、天门冬氨酸氨基转移酶(AST)、γ-谷氨酰转移酶(γ-GGT)、碱性磷酸酶(ALP)、肌酸磷酸激酶(CK)活性及总胆红素(TBIL)、直接胆红素(DBIL)、尿素氮(BUN)、肌酐(CRE)、总胆固醇(CHO)、总蛋白(TP)、白蛋白(ALB)、血糖(GLU)含量均无明显变化,与对照组相比差异均不显著(P>0.05);随着APS添加剂量增加,Ⅱ、Ⅲ、Ⅳ组血清中甘油三酯(TG)含量呈下降趋势,且给药第10天时显著低于对照组(P<0.05)。综上所述,生产中以黄芪多糖推荐剂量饲喂奶牛安全可靠,达到10倍推荐剂量时也无安全性问题,黄芪多糖可作为一种安全的抗氧化剂和免疫增强剂应用于奶牛养殖。

Abstract: This experiment was aimed to explore the effect of Astragalus polysaccharides (APS) on serum biochemical indexes of lactating Holstein cows.According to the similar age,parity and weight,40 Holstein cows in lactation period were selected and randomly divided into four groups with 10 cows in each replicate in a single-factor completely randomized block design.Group Ⅰ was the control group which fed with basal diet without APS,groups Ⅱ,Ⅲ and Ⅳ were fed basal diet supplement with 10,50 and 100 g/(cow·d) APS,respectively.The experiment lasted for 20 days.The results showed that with the increase of the APS level,the serum activities of ALT,AST,γ-GGT,ALP,CK and the serum contents of TBIL,DBIL,BUN,CRE,CHO,TP,ALB and GLU in groups Ⅱ,Ⅲ,Ⅳ were no significant differences compared with the control group (P>0.05).With the increase of the APS level,the serum content of TG in groups Ⅱ,Ⅲ,Ⅳ had a decreased tendency,and 10 days after using medicine,it was significantly decreased compared with the control group (P<0.05).In conclusion,feeding the cows with recommendatory dosage of APS in the actual production condition was safe and reliable.10 times as the recommendatory dosage of APS was also safe,and APS was able to regard as a security antioxidant and immunopotentiator in cow breeding.
