Chicken house attics can be tapped to warm broilers

23.03.2010
Reducing the cost of keeping broiler chickens warm could result from research by Agricultural Research Service (ARS) scientists and university cooperators.

Insulating, ventilating and heating broiler chicken houses can be expensive, especially when fuel prices are high, according to study leader Joseph Purswell, an agricultural engineer at the ARS Poultry Research Unit in Mississippi State, Miss. He worked with Barry Lott, a retired professor at Mississippi State University, to investigate ways to reduce the energy costs of heating chicken houses, thus increasing profits for producers.

They found that the air that gathers in broiler house attics can be as much as 20 degrees Fahrenheit warmer than the air outside. The attic air is at least 5 degrees F warmer about 70 percent of the time.

Purswell and Lott developed a ventilation system that uses ceiling inlets to redistribute solar-heated attic air, as opposed to bringing in cooler, outside air. They began gathering data in 2006 from a Mississippi chicken producer who installed several broiler houses based on their design.

The scientists concluded that circulating the warmer attic air within the chicken houses reduced the demand for heating fuel by about 20 to 25 percent. In one study in mild weather conditions, the technology reduced fuel use by 35 percent.

Similar technology has been applied to swine and layer facilities, but this is the first research to examine whether the technology works with broiler houses, which have a significantly different construction.

Commercial interest in the technology has increased with rising fuel prices over the past several years, according to Purswell. That has prompted producers throughout the broiler belt to request information on how to take advantage of the technology.

The ventilation system also reduces moisture and ammonia inside the houses, improving air quality.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
