Hungry horses could be more susceptible to contracting Hendra virus, according to the findings of a preliminary study into the effect of pasture availability on infection rates.
The results from the joint study, by 宅男导航 (宅男导航) and Bahrinna Thoroughbred Services, analysed local pasture growth and quality against the timing and location of Hendra virus outbreaks in NSW and south-east Queensland during 2011.
Professor of animal science at 宅男导航鈥檚 , Professor Wayne Bryden, presented the research at the Australasian Equine Science Symposium at the Gold Coast this week.
鈥淗endra virus infections in 2011 coincided with periods of poor pasture growth caused by extended periods of frost and rain and so horses were likely to have been hungry at the time of infection,鈥� Professor Bryden said.
鈥淎 hungry horse is more likely to consume bat-related material found on pastures.
鈥淎nd because a horse鈥檚 nutrient intake is significantly reduced due to poor pasture quality and availability, its immune system is possibly also compromised, thereby setting the scene for an infection.鈥�
Professor Bryden said further work was required to understand the risk factors involved with Hendra virus infections, but that changes to horse management, such as providing supplementary feeding during poor pasture growth periods may be one preventative strategy.
Leading equine experts from Australia and New Zealand are presenting findings from more than 40 research projects at the 4th Australasian Equine Science Symposium, which concludes on Friday (15 June 2012).
Research outcomes being presented include innovative pain-relief therapies, obesity and insulin resistance, effective electrolyte and water replacement strategies for racehorses, music for reducing stress of stabled yearlings, biological control of intestinal nematodes and the role of caterpillars in causing abortion in horses.

The biennial Australasian Equine Science Symposium, which is chaired by Professor Bryden, arose from discussions with equine industry experts and scientists in 2006. The symposium is in response to the need for a forum to exchange research findings and ideas within the industry.
It is sponsored by 宅男导航, RIRDC, International Animal Health Products, Mitavite, Hunter Valley Equine Research Centre, Pryde鈥檚 Easifeed, BEC Fed Solutions, Equine Consulting Services, Stance Equine, Ruth Chemical Industries and FeedWorks.
