Lasering-in on livestock behaviour

29.04.2004


The use of laser technology to provide new insights into animal behaviour could lead to improved livestock management practices, according to the leader of a Rockhampton-based CSIRO Livestock Industries research group, Dr Dave Swain.



In a recent trial, Livestock and Environment Group researchers used a survey laser to monitor and record the movement of cows and calves around a paddock.

"The laser allowed us to track the animals without physically handling them, so we didn’t disrupt their natural behaviour or welfare," Dr Swain says.


Mounted on a scaffolding tower about 250m from the animals, the laser fires low-level radiation beams which are deflected off animals to a data recorder which calculates their distance from the laser.

Dr Swain says the technology - and spatial data arising from its use - promises to provide accurate and detailed behavioural information for improved livestock management.

"Now that we’ve established that this non-invasive technology works, we’ll be able to use it to derive meaningful information about how animals use their environment, and features such as water and supplements, and how they interact with each other," he says.

"For example, we could look at how the behaviour of a cow impacts on calf development and productivity. If there is a relationship, we could potentially improve productivity by selecting cows for their ability to be good mothers."

Information on how animals use their pasture as they move around paddocks, could also help scientists devise ways to improve livestock growth rates and avoid environmental degradation.

Dr Swain says the lasers will complement and enhance other research tools aimed at understanding behavioural grazing strategies, cow-calf interactions, and the impact of animals on the environment.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
