Campylobacter spp. have been isolated from live poultry, production environments, processing facilities, and raw poultry products. Environmental sampling in a poultry grow-out house, combined with carcass rinse sampling from the same flock, may provide a relative relationship between pre- and postharvest Campylobacter contamination. Air samples, fecal/litter samples, and feed/drink line samples...
Poultry litter is a mixture of bedding materials and enteric bacteria excreted by chickens, and it is typically reused for multiple growth cycles in commercial broiler production. Thus, bacteria can be transmitted from one growth cycle to the next via litter. However, it remains poorly understood how litter reuse affects development and composition of chicken gut microbiota. In this study, the ...
The quality comparison of eggs laid by laying hens kept in battery cages and in a deep litter system
At present the laying hen rearing is transformed into alternative housing systems which include a deep litter system. As for the poultry nutrition, the replacement of animal protein with vegetable protein in poultry feed is applied. Therefore, in an experiment we evaluated the quality of eggs from laying hens in the cage system as compared to the deep litter system with vegetable protein substi...
The effects of soil compaction on soil physical properties may alter soil microbial activities and processes, including carbon (C) cycling, and possibly affect agricultural production and environmental degradation. This study investigated the effects of surface soil compaction on soil C mineralization in a claypan soil amended with poultry litter (i.e. turkey excrement mixed with pine shavings ...
