摘要
为获得荣昌猪抵抗运输应激的能力及运输应激对荣昌猪影响的规律,选择40日龄荣昌仔猪36头,分试验组及对照组,试验组仔猪在15℃室外温度、50 km/h的车速条件下运输2 h约100 km,分别监测运输前、运输后30 min、运输后第1天、运输后第3天、运输后第7天、运输后第15天试验组及对照组仔猪肝脏主要生化指标和腹泻发生率。结果表明,运输后30 min时肝脏主要生化指标谷丙转氨酶、谷草转氨酶、谷氨酰氨基转移酶的指标升高明显,均显著大于正常范围值,运输后第3天下降,运输后第15天时逐渐恢复接近正常值;经过2 h运输的试验仔猪比位于圈舍的对照组仔猪更易腹泻,腹泻率达33.3%。荣昌仔猪较易受运输应激的影响,运输应激后较易出现腹泻。
In order to getting capacity and rules of Rongchang pig against transport stresses,36 Rongchang piglets with 40 day old were divided into test group and contral group.those piglets in the test group had been transported for 2 hours, and totaled tol00km by 50 km/h and in 15 ~C outdoor condition,main biochemical indexes of liver of them before transport ,30min,3th day ,Tth day,15th day after transport and diarrhea rate were detected respectively. The results showed that main biochemical indexes is changed more obviouser than that of the contral in 30 minutes after transport,alanine aminotransferase, aspartate aminotransferase, gamma glutamyl amino transfer enzyme index is increased significantly,and is higher than the normal range of them,and those main indexes is reduced in 3th day af- ter transport, and radually recovered close to the normal value 15th days after the transport ; the piglets in the test group are more likely to diarrhea than those of the contral group,diarrhea rate of the piglets in lhe test group get to 33.3%.capacity of Rong Chang piglets against transport stress is not good, and is easy to diarrhea after transport.
