Effect of Oxytropis glabra DC Poisoning on Serum Protein and Blood Fat in Hetian Sheep

12 Hetian sheeps were randomly and equally divided into 3 groups(the control group,experimental groupⅠ,groupⅡ)to investigate the effect of Oxytropis glabra DC poisoning on serum protein and blood fat,then reveal the toxicity mechanism of Oxytropis glabra DC.These experimental groups of sheeps were fed daily contents of 10 or 20g/(kg·BW)until typical symptoms were observed.The contents of serum protein and blood fat were determined respectively before challenge test and at intervals of 7days in this test.Meanwhile,the serum proteins were analysed by electrophoresis.After 42 days test,the results demonstrated that the contents of serum TP,GLO,α-globulin and HDL-C did not significantly change in each group(P0.05);the contents ofβ-globulin,TC,LDL-C and VLDL-C in experimental groups were higher than normal control group,the contents of ALB,γ-globulin and TG in experimental groups were lower than normal control group,with significant differences between the experimental groups(P 0.05or P 0.01);the content ratio of albumin to globulin(A/G)in test groups were decreased.The results showed that the sheeps' liver displayed different degrees of damage by poisoning of Oxytropis glabra DC.
