TL;DR: In this article, a field survey of dust concentrations within and dust emissions from cattle, pig and poultry buildings was conducted in England, the Netherlands, Denmark and Germany, where measurements of inhalable and respirable dust concentrations were made in 329 buildings and CO 2 within and outside the buildings were also measured to estimate ventilation rates for dust emission calculations.
Journal ArticleDOI
Is precision livestock farming an engineer's daydream or nightmare, an animal's friend or foe, and a farmer's panacea or pitfall?
TL;DR: In this paper, the development of precision livestock farming (PLF) from the view point of the engineer, the farm animal and the farmer is reviewed, and it is concluded that PLF is an embryonic technology with great promise but one that requires considerable research and development before uptake.

TL;DR: The concentration of airborne endotoxins and microorganisms in livestock buildings (cattle, pig, poultry) was surveyed in four European countries (England, The Netherlands, Denmark and Germany) as mentioned in this paper.
Journal ArticleDOI
A review of livestock monitoring and the need for integrated systems
TL;DR: The application of integrated monitoring system techniques, in which information from sensors, databases, mathematical models and knowledge bases are combined and interpreted, will enable the maximum potential of this information to be realised.
Journal ArticleDOI
Concentrations and emission rates of aerial ammonia, nitrous oxide, methane, carbon dioxide, dust and endotoxin in UK broiler and layer houses
TL;DR: Overall the air quality within the poultry houses was unsatisfactory as judged by the dual criteria of farmer health and bird performance.
