Sunny Day Farm was the home of the highest producing registered Jersey herd in the world at the time this study was conducted. The cows are housed in a freestall barn and manure is removed from the barn using a flush system. The manure treatment system on this farm includes the following components in series: an inclined stationary screen separator, a two–chambered settling basin, and a lagoon....
In the Netherlands, extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli bacteria are highly prevalent in poultry, and chicken meat has been implicated as a source of ESBL-producing E. coli present in the human population. The current study describes the isolation of ESBL-producing E. coli from house flies and blow flies caught at two poultry farms, offering a potential alternativ...
Livestock is a vital source of methane and nitrous oxide gas which are considered as hazardous greenhouse gas (GHG) causing global warming. This study was conducted to assess GHG emissions from different livestock categories of different (small, medium, large) dairy farming in Bangladesh by using IPCC guideline 2006 and CIGR 2002. The emission rate of CH4, N2O (mainly emits from manure) is incr...
Insects play a significant role in recycling many forms of waste and other accumulated nutrients in the environment. Attempts to harness the power of insects for manure management have not been particularly successful or widely adopted. Although additional research is needed, the current state of the technology for utilizing the black soldier fly (Hermatia) for processing hen and swine manure a...
In several areas with a high density of animal production, manure is no longer exclusively considered as a fertiliser. In order to limit the production or a more environmental friendly use, efforts are done to reduce the mineral excretion. In such a context, both from governmental side as for the producer a reliable calculation of the on farm production is useful. Based on the input (feed) outp...
When handled separately from manures, dairy farm effluents (DE) are costly to manage because of their low nutrient content and large volume. In anticipation of using surface irrigation to lower the land application cost of DE, this projects investigated the impact, on DE characteristics, of different sources and storage systems. Milk house wastewaters were monitored on two farms using a 500 l m...
Animal manure management is a real challenge to minimize environmental impacts and ensure that this valuable material efficiently used in circular economy context. One of the main limitations for larger use animal as fertilizer availability land receive it an area close farm. Indeed, traditionally cereals feed growth, but soil occupied with these crops might not be enough all produced and/or pa...
A geographic information system (GIS) based manure application plan has been developed for the site-specific application of animal waste to agricultural fields in the Westbrook sub-catchment of the Murray-Darling Basin, south-east Queensland, Australia. Sites suitable for animal waste application were identified using a GIS based weighted linear combination (WLC) model. The degree of land suita...
and Implications This on-going study is continuously monitoring emissions of gases including ammonia, hydrogen sulfide, carbon dioxide, methane and (intermittently) selected odorous volatile organic compounds (VOCs) as well as particulate matter (PM) from a 2500-head sow farm consisting of two gestation barns and one farrowing barn in central Iowa. An on-farm instrumentation shelter houses the ...
This paper presents the results of excavations carried out in Chalcolithic contexts from walled enclosure Ota (Alenquer, Portugal). Six new absolute dates allow discussion stratigraphical evidence and chronologically frame zooarchaeological taphonomical analysis faunal assemblage. Domesticated swine, caprine bovine are prevalent, while wild species, most notably leporids, but also red deer, aur...
