The mucous exudate from the nose indicates the presence of a bacterial complication.

The mucous exudate from the nose indicates the presence of a bacterial complication.

Wherever I turn, I come up with the same ‘minor’ factoid about factory farm pigs: Ammonia and other gases from manure irritate animals’ lungs, to the point where over 80% of US pigs have pneumonia upon slaughter. Yes, that’s 80% of US pigs with pneumonia upon slaughter.

From the ‘The Pig Site,’ I learned that clinical signs of elevated levels of ammonia and other gases in the piggery “include increased coughing and respiratory rates, irritation of the mucosa lining the respiratory tract and an increased incidence of pneumonia. Pigs are restless, uncomfortable and may show increased levels of vice, such as tail biting, ear biting and flank chewing.” These are probably signs of mental anguish as well. Pigs are more intelligent than dogs and chimps.

“Increased levels of vice,” indeed! But where exactly is the vice?
