In 126 gilts of the Netherlands Landrace breed and eighty-one gilts of the Large Yorkshire breed, slaughtered when they had attained a weight of 100 kg., radiography of the nasal cavities was carried out, followed by post-mortem studies of these cavities. Macrocopic examination of the transverse section at the level of the first premolar tooth showed that the incidence of atrophy as well as of hypertrophy of the turbinate bones was higher in pigs of the Large Yorkshire breed than it was in those of the Landrace breed. The ventral coils of the ventral conchae were most commonly affected in the two breeds. When the X-rays were assessed using the system suggested by Done (3), a discrepancy between the X-rays and the post-mortem findings was observed in a large number of cases. Possible causes of this discrepancy are discussed. The results do not warrant the development of a radiographic technique which can be used in field conditions in the Netherlands to examine the nasal cavities in establishing a diagnosis of atrophic rhinitis.
