猪运输应激血液生化指标变化

The Alterations of Blood Biochemical Indexes of Pig Due to Transportation Stress

４月龄猪８头（２４，早４），在最高气温３０℃下，用汽车运输４ｈ多（约１６０ｋｍ）。运输前和运输后连续５ｄ采集静脉血液，进行主要生化指标检验。结果：与运输前相比，血清总蛋白和球蛋白在运输停止时升高（Ｐ＜０．０１），运输停止后第１～５天降低（Ｐ＜０．０１）；尿素氮和甘油三酯运输后第１～２天升高；血清钠运输后第１～３天降低，血清钾运输后第１～５天降低（Ｐ＜０．０１）；血清ＣＫ和ＡＳＴ在运输停止时和运输停止后第１天活性升高，ＬＤＨ只能保持１ｄ活性升高；血清白蛋白、葡萄糖、胆固醇、无机磷、皮质醇和血乳酸运输后都有不同程度升高，但统计学检验差异不显著。

Eight 4-month-old pigs(♂4,♀4)were used to determine the alter-ations of blood biochemical indexes due to transportation stress.The experiment ani-mals were loaded with truck and transported at 30℃ atmospheric temperature for 4hours'drive(traffic mileage,160 km).he blood plasma and serum samples were col-lected aiid examined before transportation and at day 1,2,3,4 and 5 after transporta-tion.The results obtained were as follows: the concentrations of serum total proteinand globulin have raised( P<0.01)at the transportation stopping time, while dropped(P<0.01)at day 1～5 after transportation. The contents of urea nitrogen and trigly-cerides were higher at day 1～2 after transportation.Blood sodium and potassium de-creased at day 1～3and day 1～5 after transportation respectively.The activities ofserum creatine kinase(CK)and asparate transaminase(AST)strenthened when thedrive stopped and at day 1 after transportation,while the raised activitv of lactate dehy-drogenase(LDH)ren1ained only 1 day.The serum albumin,glucose,cholesterol,inor-ganic phosphorous, cortisoal and lactic acid increased to different extent after trans-portation,but the differences were not statistically significant.
