What are the social costs and benefits of lignite application to reduce ammonia emissions in intensive feedlot?
Sign Up to like & getrecommendations! Published in 2020 at "Journal of environmental management"
DOI: 10.1016/j.jenvman.2020.110821
Abstract: Recent studies demonstrated that lignite application in feedlot can mitigate ammonia (NH3) emission from intensive livestock production, which is an important source of environmental pollution. However, the use of lignite on feedlot requires mining and… read more here.

DOI: 10.1016/j.vetmic.2018.06.007
Abstract: Specific nasopharyngeal bacterial communities can provide colonization resistance against respiratory pathogens in cattle. However, the role of bacterial communities of the lower airways in respiratory health remains largely unknown. Therefore, our objective was to compare… read more here.
