Abstract: Australian workers have demonstrated that infectious challenge per se is insufficient for the development of pathological lesions of salmonellosis in sheep in all but a few cases. Inanition is the major risk factor. The purpose of this letter is to: support those findings; to add some observations from a longer voyage than has been previously studied; and to suggest that sahnonellosis in sheep exported live from New Zealand could be almost completely prevented by ad lib.feeding. I accompanied a shipment of sheep from Napier and Timaru to Dammam in Saudi Arabia during the period 11 December 1993 to 19 January 1994 (Voyage 94 of the New Zealand series).
