چکیده
At a time of global warming, growing environmental concerns and a political situation that is making many industrialised countries critically review their dependency on Middle Eastern oil, the need to develop alternatives to fossil fuels is becoming increasingly important. And this is not just a recurring demand from environmentalists; most industrialised countries signed the Kyoto Treaty, committing themselves to lowering their carbon

Response of antibiotics and resistance genes to high-intensity and low-intensity manure management.
The purpose of this study was to determine the response of antibiotics and antibiotic resistance genes (ARG) to manure management. A pilot field study was conducted using horse manure containing no antibiotics, into which chlortetracycline (CTC), tylosin (TYL), and monensin (MON) were spiked and compared to unspiked controls. Subsequently, a large-scale field study was conducted comparing manur...
متن کاملAmmonia and greenhouse gases losses from mechanically turned cattle manure windrows: A regional composting network.
An on-farm composting network operates in the Basque Country (northern Spain), in which solid manure produced in livestock farms (mostly dairy and beef cattle) is composted through windrow turning. This network aims to produce a valuable resource (compost) for the farmers whereas the volume of the solid manure was reduced at farm level The objective of the study was to assess the gaseous losses...
متن کاملGreenhouse gas emissions during cattle feedlot manure composting.
The emission of greenhouse gases (GHG) during feedlot manure composting reduces the agronomic value of the final compost and increases the greenhouse effect. A study was conducted to determine whether GHG emissions are affected by composting method. Feedlot cattle manure was composted with two aeration methods--passive (no turning) and active (turned six times). Carbon lost in the forms of CO2 ...
متن کاملReduction of ammonia inhibition of organic matter degradation by turning during a laboratory-scale swine manure composting
Submission : January 20, 2013 Accepted : February 20, 2013 Abstract — Inhibitory effect of ammonia on the organic matter degradation at the outer region was simulated using a composting system consisted of two miniature-scale reactors with different constant temperature connected in series. The lower and upper reactors were incubated at 70 and 40 oC, respectively. Composting runs were conducted...
متن کاملPSA - Poultry Genetics
An experiment was conducted to determine the effects of mechanical pile turning/mixing with the addition of hardwood shavings to manure in deep pit layer housing. A commercial six row deep-pit poultry house were assigned treatments of : two rows each with 357.5 kg shavings base-mixed (treatment A), two rows each with 725.9 kg shavings-mixed (B), one row mixed without added shavings (T), and one...
