Differential diagnosis: Other
Sudden death ocurred in a 8 week old weaner pig. It was in good condition. Post-mortem examination revealed the stomach was in the thorax.
Diaphragmatic hernias in swine occur sporadically, often in a single animal. They are usually congenital or the result of traumatic accidents. Dyspnea is usually associated in the acute cases. The degree of dyspnea may vary from subclinical to incompatible with life, depending on the amount of herniated viscera. If the stomach is herniated, it may bloat and the animal may deteriorate rapidly, as in this case. In chronic cases, systemic signs such as weight loss may be more prominent than respiratory signs.
