【摘要】：选择3头荷斯坦奶牛,饲喂0.182mg/kg(BW)的镉21d,研究探讨了镉对奶牛血常规、尿常规、血清指标的影响.结果表明:给镉后奶牛红细胞数量(RBC)、血红蛋白浓度(Hb)显著性降低(P0.05),红细胞压积(HCT)有降低的趋势(P0.05),平均红细胞体积(MCV)、平均红细胞血红蛋白量(MCH)、红细胞平均血红蛋白浓度(MCHC)均无显著变化(P0.05);尿比重(SG)和蛋白质(PRO)有增加的趋势(P0.05),白细胞(WBC)、酮体(KET)、尿胆原(URO)、胆红素(BIL)、隐血(BLD)、葡萄糖(GLU)和亚硝酸(NIT)均为阴性;血清总抗氧化能力(T-AOC)、超氧化物歧化酶(SOD)有降低的趋势(P0.05),丙二醛(MDA)、谷草转氨酶(AST)、谷丙转氨酶(ALT)有升高的趋势(P0.05),谷胱甘肽过氧化物酶(GSH-Px)、碱性磷酸酶(ALP)无显著性变化(P0.05).
[Abstract]:Three Holstein cows were fed with cadmium (0.182 mg / kg BW) for 21 days. The effects of cadmium on blood routine and urine routine were studied. The results showed that red blood cell (RBC), hemoglobin (HB) and HCT decreased significantly (P 0.05), mean erythrocyte volume (MCV) and mean erythrocyte hemoglobin (HCT) decreased. There was no significant change in the mean hemoglobin concentration (MCHCC), but there was no significant change in the mean hemoglobin concentration (P0.05); the urine specific gravity (SGG) and protein propofol (PROP) tended to increase (P 0.05), WBCU, KETP, UURON, bilirubin BILL, BLDD, GLU and NITs were all negative. Serum total antioxidant capacity (T-AOC), superoxide dismutase (SOD), and malondialdehyde (MDA), aspartate, glutamic oxalacetic transaminase (AST), glutamate-pyruvic transaminase (alt), and glutathione peroxidase (GSH-PxX, alkaline phosphatase) had a tendency to increase (P0.05), while glutathione peroxidase (GSH-PxX) and alkaline phosphatase (ALP) had no significant change.
