Adequate ventilation in pig housing prevents heat stress, respiratory disease, and ammonia buildup. Poor air quality is a major welfare issue in intensive pig production.
Pigs kept in poorly ventilated buildings suffer chronically from respiratory irritation, heat stress, and toxic gas exposure. Ammonia and hydrogen sulfide from slurry pits accumulate without adequate air exchange, causing eye and lung damage. Welfare-focused ventilation design ensures fresh air reaches all animals, maintains comfortable temperatures year-round, and removes harmful gases - fundamentally improving the quality of the pigs' daily experience.
