- •
Emissions of ammonia were determined during three finishing pig production periods.
- •
N losses were reduced by 66, 44 and 71% during spring, summer and autumn.
- •
Ventilation was an important driver for ammonia emissions in spring and autumn.
- •
Less methane emission with acidification was indicated, but emissions were generally low.
- •
No consistent effects of acidification on nitrous oxide or hydrogen sulphide emissions.
