Quantifying ammonia reduction figures in industrialised broiler housing with the use of Pruex bacteria

使用食品级芽孢杆菌的微生物清洁在过去七年里一直在医院使用。使用芽孢杆菌清洁表面已被证明比其他化学消毒剂更有效和可持续。Pruex在一系列农业应用中率先使用_Bacillus_，包括通过将鸟类粪便转化为更干燥、可能更营养密集的产品来清洁家禽舍，这有可能减少硝酸盐渗入环境，改善鸟类健康和农场盈利能力。早期试验表明，温室气体一氧化二氮以及氨和致病病原体的减少。当联合使用时，_Bacillus_治疗显著提高生长、产蛋、福利和整体盈利能力。事实证明，在商业环境中，由于大型家禽舍的通风问题，量化温室气体的减少具有挑战性；气体能够逸出，处理细菌容易通过通风系统污染控制棚；在商业环境中，这是有益的，但在试验环境中，需要控制通风，以确保准确测量温室气体和氨的减少。本项目将调查在受控家禽棚内杆菌处理产生的氨、二氧化碳、甲烷和氧化亚氮的减少情况，目的是量化氨的减少数字。

Microbial cleansing, using food grade _Bacillus_, has been in use in hospitals for the past seven years. Using _Bacillus_ to clean surfaces has proven more effective and sustainable than alternate chemical disinfectants. Pruex are leading the use of _Bacillus_ for a range of agricultural applications including cleansing poultry houses by converting bird excrement to a drier, potentially more nutrient dense product, which has the potential to reduce nitrate leaching into the environment, improve bird health as well as farm profitability.Early trials have shown reductions in GHG nitrous oxide as well as ammonia and disease causing pathogens. When combined, _Bacillus_ treatment dramatically improves growth, laying, welfare, and overall profitability. Quantifying the reductions in GHGs has proved challenging in commercial settings due to the ventilation in large poultry sheds; gases are able to escape, and the treatment bacteria can easily contaminate the control shed through the ventilation system; in a commercial setting this is beneficial, however in a trial setting, the ventilation needs to be controlled to ensure accurate measurements of the reductions in GHGs and ammonia.This project will investigate the reductions in ammonia, carbon dioxide, methane, and nitrous oxide produced by _Bacillus_ treatment in a controlled poultry shed with the aim of quantifying the ammonia reduction figure.
