The mean rate of injuries calculated in this population was only 0.45 pigs dead or injured per 1000 pigs transported, with only .09% dead or euthanized. This increased slightly during quarters 3 and 4, probably reflecting heat stress. The origin of the truckload had a considerable effect on the rate, probably reflecting management decisions on each pig’s ability to withstand the stress of transport. There was a consistent pattern of increasing risk according to the trip distance in both, death/injury and dead on arrival. In both cases, a distance longer than 652 miles increased the rate. In conclusion, under the conditions studied, transportation did not pose a high risk for injuries or deaths in the population studied.
