The greater the distance lambs have to be transported from their home range to the pens where they are to be fed, the more chance they have of developing paratyphoid dysentery. This disease is classified as a shipping disease and its occurrence is influenced and enhanced by long journeys on the cars or delays in transit with poor feeding accommodations.
