TL;DR: In this article, the potential for reducing nitrogen and carbon emissions and plant nutrient leaching during storage of solid deep litter from dairy cow houses was examined in an assessment of the potential of reducing emission and leaching losses by compaction, mixing and covering the deep litter.
TL;DR: Future trends in investments for housing system in egg production will have to take into account several factors apart from the degree of success from technical development of each system, including climate, feed, bird genotype, group size, and design and location of nests, perches and litter.
Abstract: Except for conventional cages, the most common housing systems for laying hens comprise deep litter, aviaries and more recently furnished cages. Layers in floor systems may also include out-door ke...
TL;DR: In this article, sawdust was used for two different deep-litter systems for fattening pigs (System 1 and 2) and the differences between the systems were the amount of litter per pig, the size of the sawdust particles and the way the bed was treated.
TL;DR: In this article, the authors used dynamic chambers covering three heaps of deep litter from a house with dairy cows to measure emissions of ammonia (NH3), nitrous oxide (N2O), methane (CH4), and CO2.
TL;DR: Cold stress seriously negatively affects the welfare of cocks and heterophil-to-lymphocyte ratio varied from breed to breed, differences between housing systems being significant in 2 breeds.
