Pampered porkers and woolly well-being

19.09.2003


A CSIRO Livestock Industries researcher, Dr Caroline Kerr, will use an award from the Australian Government Department of Agriculture, Fisheries and Forestry to ascertain whether certain immune system molecules can be used to reduce livestock stress levels.



Dr Kerr is the Australian Wool Innovation winner and one of 18 researchers and innovators to be awarded the 2003 Science and Innovation Award for Young People in Agriculture, Fisheries and Forestry.

Presented in Canberra by the Minister for Agriculture Fisheries and Forestry, the Hon. Warren Truss, the awards include grants of up to $8,000 to facilitate recipients’ long-term research into areas that will benefit their industries.


Dr Kerr will look into the role suppressors of cytokine signaling (SOCS) molecules play in varying stress levels and growth performance in pigs and sheep.

"Research has shown that even though livestock animals may appear to be happy and comfortable, low levels of stress will limit their capacity to grow," Dr Kerr says.

Learning more about the conduits of stress in livestock animals will provide important benefits to producers and consumers.

"Animals live with stresses we can all relate to, such as heat stress on a hot day, stress from illnesses and ’animal to animal’ tensions," Dr Kerr says.

"These tension factors can affect how the animal’s brain and immune system works, which then affects their ability to fight diseases and grow. Not surprisingly, a stressed animal doesn’t grow as fast as a relaxed animal," she says.

"It is difficult to manage what you can’t measure. By gaining an improved understanding of how stress pathways work to determine measurements of stress, we can better manage this factor."

Dr Kerr’s research will focus on identifying the role the SOCS-2 immune protein plays in the stress pathway of pigs and sheep.

"So far, most of the SOCS proteins have only been identified in humans and rodents. In mice, when the SOCS-2 is removed, mice grow much larger. It may be that SOCS-2 can provide a measure of stress in livestock animals," Dr Kerr says.

By identifying measurements of livestock stress, management practices and breeding systems can be changed to improve animal welfare.

"It may be possible to manipulate the SOCS-2 pathways to adjust an animal’s response to stress. This would be of value during times of unavoidable stress, such as transport and weaning. Also, genes within the pathway would be candidate marker genes for breeding stress-tolerant livestock," she says.

The awards enable young people to undertake innovative projects related to an agriculture, fisheries, forestry or natural resource management related industry and are managed by the Bureau of Rural Sciences in the Australian Government Department of Agriculture, Fisheries and Forestry.

"It is vital that we encourage young Australians wishing to undertake innovative research - in the laboratory or on the farm - that will help boost the competitiveness of our rural industries and the long-term viability of our regional communities," says Mr Truss.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
