Gizzard erosions as a cause of mortality in white leghorn chickens

Increased mortality connected with gizzard erosions has been observed in several flocks of White Leghorn chicks in Sweden. Bacterial infection of the gizzard wall was a common finding in chicks that had died from the disease. Infection with Clostridium perfringens is supposed to be the main cause of mortality, but the primary cause of the gizzard lesions has not been established.
