摘要
研究我国典型的禁食禁水长途运输和运输后恢复对肉牛血液指标的影响,以期为建立符合我国国情的运输动物保护法规、改进运输车辆提供数据和理论依据。采用自身配对试验设计,分别在运输前、卸车后0 h和卸车后72 h同期采集10头体质量(312.6±11.6)kg的西门塔尔杂交母牛颈静脉血,进行血液激素指标、生化指标、血常规指标和离子指标检测。结果表明,卸车后0 h血清T_3、T_4和AST显著升高,GH、ALP、MCV、Ca^(2+)和Mg^(2+)显著降低,COR、ALT、TP、ALB、GLU、LDH、CK、WBC、RBC、HGB、HCT、K^+、BASO%、Na^+和Cl^-无显著变化。卸车后72 h血清T_4、GH、AST、Ca^(2+)和Mg^(2+)恢复到运输前水平,TP和LDH显著低于卸车后0 h,但与运输前差异不显著,MONO%和EO%与运输前差异不显著,T3和ALP与卸车后0 h差异不显著,与运输前差异显著,COR、ALT、ALB、GLU、MCV、NEUT%、BASO%、Na^+和Cl^-显著低于卸车后0 h和运输前水平,LYMPH%显著高于运输前水平。结果提示,禁食禁水长途运输条件下,动物代谢水平升高、肝脏受损、离子平衡失调、脱水,免疫机能未受明显损害。运输后恢复72 h,动物未得到完全恢复。该研究可为建立符合我国国情的运输动物保护法规、改进运输车辆提供数据和理论依据。
Abstract：To study the effcts of Chinese typical long-distance transport and recovery after transport on the haemotological indices of cattle,and then to provide reference to establish rules on the protection of animals during transport and progress vehicle, ten Simmental heifer with （312.6 ± 11.6） kg weight were sampled for hormone, biochemistry, blood and ion analysis, before transport, 0 h after unloading and 72 h after unloading respectively. The result showed that there was signifancant increase of FT3, FT4, AST and signifancant decrease of GH, ALP, MCV, Ca^2＋ , Mg^2＋ of 0 h after transport compared with pre-transport. And there was no significant changes of COR, ALT, TP, ALB, GLU, LDH,CK, WBC, RBC, HGB, HCT, K^＋ , BASO%, Na^＋ , CL^- before and after transport. FT4, GH, AST,Ca^2＋ , Mg^2＋ recoveried at 72 h after transport, but COR, ALT, TP, ALB, GLU, LDH, MCV, NEUT%, BASO% ,Na^＋ and Cl^- did not. Compared with 0-hour after unloading,there was no significant defference of FT3 or ALP at 72 h after unloading. There was insignifant defference of MONO% or EO% between 72 h after and before transport. LYMPH% at 72 h after unloading increased. The results implied that long-distance transport with fasting induced elevating metaboilic level,liver damaged,ion imbalance,and not damaged immune function. Cattle did not recovered fully until 72 h after unloading. The results of this study are valuable for to establishing rules on the protection of animals during transport and progressing vehicle.
