Farms that use living animals for the exposure to gilts during the acclimatization and farms that had increased number of weaned piglets per sow and year were less likely to test positive for M. hyopneumoniae and less likely to develop clinical symptoms of EP in fattening pigs.

The results obtained at the commercial growing-finishing farms show that in uncontrolled conditions the water disappearance and manure production are significantly influenced by the drinker type.

Biosecurity is a useful measure to promote the reduction of antimicrobial use in the pig industry.

Organic dust extract exposure negatively affects pig macrophage activation and function, potentially enhancing host susceptibility to a variety of respiratory infections.
