Abstract
A sow of 190 kg weight suddenly died, one day before due to delivery, though seeming to be quite healthy a few hours previously. Pathomorphological investigation revealed a 11 cm wide gap in the diaphragma in the area of the hiatus oesophageus with an eventratio diaphragmatica simplex incarcerata. The pathogenesis is suggested to be a widening of an inborn small gap in the diaphragma through the increase of intraabdominal pressure due to pregnancy and beginning labour.
摘要
一头体重190公斤的母猪在预产期前一天突然死亡，尽管几小时前看起来还很健康。病理形态学检查发现，在食管裂孔区域的膈肌处有一个11厘米宽的缺口，伴有单纯性膈疝。发病机制推测为，由于怀孕和即将分娩导致腹内压升高，使膈肌先天性小缺口扩大。
