为了研究安徽省内近距离运输应激对育肥牛所造成的影响，试验选择21头大别山小黄牛（公12头，母9头）进行从运输前和到达饲养场后7 d 的研究。测定分运输前（0 d），到场后1 d 和7 d 3个阶段。每个阶段从牛颈浅静脉无菌采血2份，1份加入肝素钠抗凝用于白细胞计数（WBC），红细胞计数（RBC），血红蛋白浓度（HGB），红细胞压积（HCT）和平均红细胞血红蛋白浓度（MCH）等血常规指标测定；1份不加抗凝剂，分离血清用于测定生长激素（GH）、皮质醇（COR）、碱性磷酸酶（ALP）、尿素氮（UN）以及血清钠（Na）、钾（K）水平，同时称量试验牛平均体重。结果表明，试验牛运到养殖场后，受运输应激影响，体重下降明显（P＜0．05）。与0 d 相比，在1 d 时试验公母牛的 WBC，RBC，HGB，HCT 和 MCH 升高（P ＜0．05或 P＜0．01），7 d 时，公母牛部分血常规有变化（P ＜0．05）；在1 d 和7 d 时，试验公母牛 GH 和 ALP 的水平下降（P ＜0．05或 P ＜0．01），COR、UN 水平升高（P ＜0．05或 P ＜0．01）；在1 d 时，试验公母牛血清 Na 水平升高（P ＜0．05）；在1 d 和7 d 时公牛血清 K 水平下降（P ＜0．01），母牛在1 d 时血清 K 水平下降（P ＜0．05）。母牛抗应激能力高于公牛。

To study the stress influence of short range transport on fattening cattle in Anhui province,21 dabie mountain yellow cattle(male 12,female 9)were chosen for the test.The trial lasted for 8 days and divided into 3 stages,pre-shipment (0 d),arrived at the scene (1 d)and 7 days (7 d).The blood was col-lected from the transjugular sterile and aliquoted 2 copies in every stage,one of accession heparin anticoag-ulation for the determination white blood cell count (WBC),red blood cell count (RBC),hemoglobin con-centration (HGB),hematocrit(HCT)and mean corpuscular hemoglobin concentration (MCH).The other for the serum without anticoagulation determinated growth hormone (GH),cortical alcohol (COR),alka-line phosphatase (ALP),urea nitrogen (UN)and serum sodium (Na),potassium (K)levels,meanwhile weighed the average weight of test cattle.The results showed the test cattle arrived at the farm,seriously affected by transport stress,weight decreased significantly (P <0.05).Compared with the pre-shipment (0 d),some blood indicators WBC,RBC,HGB,HCT and MCH values increased (P <0.05 or P <0.01);In 7d,part blood indicators of male and female cattle increased (P <0.05);In 1 d and 7 d,the levels of GH and ALP decreased (P <0.05 or P <0.01),the levels of COR,UN increased (P <0.05 or P <0.01);In 1 d,the levels of serum Na were elevated (P <0.05);In 1 d and 7 d,the levels of the bull serum K de-creased(P <0.01),the levels of the cow serum K decreased only in 1 d(P <0.05).The cows in anti-stress capacity were better than the bulls.
