Wild sheep show benefits of putting up with parasites
In the first evidence that natural selection favors an individual's infection tolerance, researchers from Princeton University and the University of Edinburgh have found that an animal's ability to endure ...
Australian sheep punched, stamped on and thrown: PETA
Footage showing sheep being violently abused by shearers—including being punched in the face and hit with tools—was condemned Friday by Australia's Agriculture Minister as "exceptional and cruel".
A model for Bluetongue disease dynamics in cattle
In a paper recently published in the SIAM Journal on Mathematical Analysis, authors Stephen Gourley, Gergely Röst, and Horst Thieme model disease persistence of a virus called Bluetongue using a system of sev ...
Study reveals livestock gut microbes contributing to greenhouse gas emissions
"Increased to levels unprecedented" is how the Intergovernmental Panel on Climate Change (IPCC) described the rise of carbon dioxide, methane and nitrous oxide emissions in their report on the physical science ...
The Sheep Genome: Study shows how sheep first separated from goats
Scientists have cracked the genetic code of sheep to reveal how they became a distinct species from goats around four million years ago. The study is the first to pinpoint the genetic differences that make ...
Assessing stress in trucked sheep
A new way of measuring the stress levels of sheep during road transport, was discussed at the Australian Veterinary Association's Annual Conference this week.
Australian sheep get high and die on toxic weed
When Australian farmer Tony Knight first saw a purple-flowering plant growing across the bushfire-scarred terrain where his sheep grazed, his first thought was that it looked like "good stock feed".
Genetic link holds key for sheep affliction
New research shows WA farmers may soon be able to breed sheep with high natural resistance to breech strike, as part of a nationwide study to identify the traits of animals able to withstand the problem.
Bighorn sheep went extinct on desert island in Gulf of California, study finds
Using ancient DNA analysis and other techniques, a research team led by conservation biologists at the University of California, Riverside has determined that bighorn sheep, so named for their massive spiral ...
Dingo found as culprit to WA sheep decline
New research suggests that unless drastic action is taken to control dingo incursions, rangeland production of wool and sheep meat in Western Australia will disappear within 30 to 40 years.

Controlling parasitic worms with genetic selection
Helminths are gastrointestinal parasitic worms that have become a major concern and source of economic loss for sheep producers around the world. A new article published today in the Canadian Journal of Animal Science review ...
Ticks kill sheep
In some lamb herds, a mortality rate of 30 percent has been recorded, albeit, no predators have been involved in these losses. The situation is so serious that the sheep industry could be under threat. It ...
Worm resistance being spread by wild hares
Wild hares have been found to be important carriers of sheep worms and are likely to be helping spread resistance to worm drenches, according to new University of Adelaide research.
