Abstract

Very little has been reported on changes in quality of eggs during shipment. Gwin (1952) reported a study involving more than a billion eggs purchased by the Armed Forces of the United States. U.S. Grades were determined by candling and inspection by trained inspectors from the Army Veterinary Corps and the U.S. Department of Agriculture. Quality loss was shown to be related to time in transit, distance or miles in transit and seasonal influences. No data were reported as to the relation of varying physical conditions during transit or position effects within the rail cars. Adams and Milam (1960) studied the effects of international shipping of eggs from Lincoln, Nebraska to New Orlenas by auto truck and thence to Rio de Janeiro by water and stored for sampling under refrigeration at the U.S. Embassy. When the eggs were 30 day old (from date of lay), they were broken and Haugh unit scores were determined in Rio de Janeriro. Eight strains of birds and 4 management systems were testd for effects on albumen condion. Neither strains nor systems of management were related nor systems of managemetn were related to rate of loss of quality in transit. The 30 day transit plus storage periot resulted in a liss of only 12.2 Haugh units which clearly demontrated the physical feasibility of international shipment of eggs.
