在欧洲，新的环境保护立法要求减少动物生产中的氨和气味排放。畜禽舍被认为是养猪生产中最大的氨排放源之一，但畜禽舍的减排技术往往需要较高的初始成本。本研究的目的是调查使用层的油和泡沫的泥浆下板条。结果发现，相对低成本，使用煎炸油（主要是菜籽油）可以减少约50%的氨和气味的排放量在断奶仔猪的住宿。这项技术的成本是每年每头猪2.60英镑。泡沫显示出较差的氨减排潜力。这种油是可生物降解的，因此储存的猪泥浆的甲烷排放量增加了约60%。
In Europe, new legislation on environmental protection requires reductions in emissions of ammonia and odour from animal production. Animal housing is identified as one of the biggest ammonia emission sources in pig production, but abatement techniques for animal houses often require high initial cost. The aims of this study were to investigate the use of layers of oil and foam on slurry under slats. It was found that relatively low-cost, used frying oil (mainly rapeseed oil) could reduce ammonia and odour emissions by about 50% in weaner accommodation. The cost for this technique was £2.60 per pig place per year. Foam showed poor ammonia abatement potential. The oil was biodegradable, so increasing methane emissions from stored pig slurry by about 60%.
