Another gaur carcass was discovered yesterday, bringing the number of wild cattle deaths in Prachuap Khiri Khan's Kui Buri National Park to 23.
An investigation into the gaur deaths has been ongoing since last month, but the reasons still remains unknown. Park officials found the latest carcass near the Pa Yang Forest Protection Unit and collected samples for laboratory testing. It is estimated that the animal died 1-2 months ago.
The investigation has so far found that samples collected from 19 carcasses last month showed no signs of disease. However, all of them were found to have a nitrate compound varying from 165 to 2,021 milligrams per kilogram, while nine samples were also contaminated with the bacteria Clostridium novyi. But it remains inconclusive that such contamination could cause the sudden death of the gaurs.
