Long duration (>10 hours) transport has been described as having either adv
erse or no effects on porcine health. However, the effect of short duration
transport on porcine health is unknown. In the present paper, pigs fed ad
libitum (n = 6) were transported for 30 minutes, anaesthetised, instrumente
d, and cardiovascular and gastrointestinal parameters were measured. Non-tr
ansported pigs (n = 6) served as controls. No significant differences betwe
en groups were found concerning blood flow in the arteria mesenterica crani
alis, heart rate, cardiac output, pulmonal blood pressure, haemoglobin cont
ent and haematocrit value. Systolic systemic blood pressure was higher (tho
ugh not significant), and diastolic systemic blood pressure was significant
ly higher in the transported pigs than in the controls. Small intestinal pH
was significantly lower in transported pigs than in control pigs. We concl
ude that a 30-minute transport of fed pigs results in small intestinal acid
osis. As small intestinal acidosis predisposes to bacterial translocation,
even short duration transport should be avoided when possible. (C) 2001 Har
