Poultry litter
Poultry litter is the mix of bedding material, manure and feathers that result from intensive poultry production. This includes litter from meat chickens (broilers), egg-laying chickens (layers) kept under barn conditions, turkeys, ducks and quails. Poultry bedding material consists of wood shavings, pine straw, peanut hulls, and other absorbent dry low-cost materials and is another possible source of pathogenic contamination for poultry. It is generally recommended that farmers keep litter as dry as possible, replace the top layer of the litter with a new one, and apply acid-based litter amendments. Keeping litter dry is a critical part of overall management on every poultry farm. Litter conditions influence bird performance, which in turn affects profits of growers and integrators. Dry litter helps control ammonia levels, provides a healthy flock environment, and reduces condemnations due to hock and footpad burns and breast blisters.
The Delmarva Peninsula, flanking the eastern shore of the Chesapeake Bay, is home to some 600 million chickens. The resulting poultry manure and some of the chicken house bedding material is usually composted and then spread onto croplands as a fertilizer.
Phosphorus-31 nuclear magnetic resonance ( 31 P NMR) and other methods of soil analysis have previously shown that two forms of phosphorus - orthophosphate and phytate (aka myo inositol hexa kis phosphate)...

Ideal Litter Conditions Proper litter conditioning is an essential tool of good management for keeping flocks healthy and profitable. Conditioning litter between flocks addresses where the birds live, which is the most crucial aspect of the poultry house environment. Ideal litter is loose and free flowing (friable), not too dry or too wet (20-30 % moisture is ideal), low in ammonia (less than 20 parts per million), uniform particle size (no large clumps) and contains...

The high cost of clean out, litter disposal and new bedding makes it economical for broiler producers to re-utilize bedding material for one, two, three or even more years of production. However, this practice makes proper litter conditioning an essential tool of good management for keeping flocks healthy and profitable. Conditioning litter between flocks addresses where the birds live, which is the most crucial aspect of the poultry house environment. Litter quality impacts bird health, skin...

A Poultry CRC-funded epidemiological survey of Australian broiler flocks has indicated that one of the protective factors against Marek's Disease virus may be the use of wood-based litter 1 . A survey of farms across the Australian broiler industry was conducted to establish the prevalence of serotype 1 Marek’s Disease virus (MDV1) in dust collected from the sheds at the end of the batch and to identify risk factors...

How much ammonia is your litter producing? Wide variations are found between flocks in how much ammonia is released every hour from the litter. In ten week old turkey flocks, moist, composted litter can produce 300 times as much ammonia each hour as dry litter with ample fresh straw added. If the ammonia level in the air exceeds 10 ppm, the turkey’s ability to fight respiratory disease is impaired. Even when the ventilation system is able to keep ammonia levels in the air low, litter which...

Preliminary results from a Poultry CRC project being undertaken by DPI&F Queensland examining the reuse of chicken litter across broiler cycles have indicated that levels of food-borne pathogens are not any higher in re-used litter than those found in single-batch rearing. The Project Leader, QDPI&F's Nalini Chinivasagam, commenced litter trials on two farms in June last year with the aim of understanding the relationship between current...

The sub-therapeutic usage of antibiotics in livestock production is under severe scientific and public scrutiny because their use has been linked to the development of antibioticresistant pathogenic bacteria, which pose a threat to human health (Smith et al., 2003). As a result of such concerns, the European Union imposed a complete ban on antibiotic growth promoters (AGPs) in livestock production on January 1, 2006. Although a complete ban on AGPs has not been implemented in many countries,...

Whether it's fried, baked, grilled or skewered, Americans are hungry for chicken, eating 90 pounds each per year. And where there's chicken, there's poop. Despite Georgia's status as the country's top meat-chicken producer, it doesn't have much of a system in place to transfer poultry litter. University of Georgia researchers, state partners and agricultural businesses recently met at a poultry litter workshop to take the first steps toward a solution. "Poultry litter is...

Is there anyone willing to share experiences with treatments against bad odour from laying hen manure? I'm mostly interested in solutions that could be applied via feed or water. I've heard of some herbal and plant extracts that can be incorporated in the feed at small concentrations with certain antibiotic efficacy that could results in a significant reduction of bad odours from the manure as simultaneously helping to reduce the microbial contamination with E....

The renewable energy and waste to energy sectors are growing rapidly in response to international pressures from Governments to reduce the amount of waste going to landfill sites and to minimize greenhouse gas emissions. As a result, the production of green energy from renewable sources and recycling are becoming increasingly important. This trend is being reinforced by the increased cost and reduced availability of landfill sites for industrial and other waste. These circumstances...

Peter Kleinman plans to take his research on the road this fall. Every month or so, the Agricultural Research Service (ARS) soil scientist will leave the rolling valleys of Pennsylvania dairy country for corn, crabs and chicken—hallmarks of the Delmarva Peninsula.
The 5,950-square-mile peninsula encompasses parts of Delaware, Maryland and Virginia. There, Kleinman will investigate an experimental method of injecting chicken litter into the soil to keep this natural fertilizer from running...

Poultry farmers have called for poultry litter to be excluded from the definition of slurry in the Nitrates Directive Action Programme.
UFU Poultry Committee chairman, Thomas Douglas, said poultry producers needed more clarity on the possible restrictions they could face under the proposed Department of the Environment and Department of Agriculture and Rural Development Nitrates Action Programme.
Thomas Douglas said: "We wish to see poultry litter defined as farmyard manure. It has a high...

If farmers want to continue using poultry litter as fertilizer on their fields, they will need to avoid excess phosphorus going on the land.
That is the advice of Dan Philbrick, Natural Resources Conservation Service district conservationist in Barry County, who talked at a meeting Feb. 11 in Neosho.
Missouri has no regulations covering phosphorus applications. Current application regulations are based on nitrogen.
Phosphorus is needed for plant growth and is not toxic to plants,...

A Western Australian Upper House MP has joined the debate over a proposed poultry litter fired power station at Muchea, saying he is concerned at the type of material that could be incinerated at the site.
There has been speculation over the types of product that could be incinerated by the power station.
The Environment Minister's conditions for the project state any fuel mix should be at least 70 per cent poultry litter, and any other component must be clean biomass.
But Greens' MLC...
