A team at the University of London is appealing to owners of property where outbreaks of Equine Grass Sickness (EGS) have occurred to get in touch as part of ongoing research into the disease.

EGS is a disease affecting pasture-grazed animals between aged between two and seven years.

Its causes are largely unknown but it is clearly linked to diet. Signs include impaired intestinal activity, and in some cases, death.

Over the past year scientists at the Centre for Pharmacognosy and Phytotherapy have been assessing the soil conditions and vegetation at sites where EGS has occurred but they wish to increase their sample size for this year.

They would also like to hear of any new cases.

To take part in the research, tel: Dr Russhawn Aldridge on 07722 376740.
