Rectal Constriction in Mal-developed Pigs with Abdominal Distension

Abstract

Pathological investigations of rectal constriction in 4 mal-developed pigs with abdominal distension were performed, and isolation of Salmonella spp. was attempted. Severe enteritis occurring several weeks after birth and sometimes causing thrombosis appeared to obstruct the rectal arterial supply. Inflammation lowered tissue regenerative capacity. Finally, rectal lesions resulted in incomplete regeneration, or annular fibrous constriction. No Salmonella spp. was isolated from the pigs.
