As livestock owners, the last thing we want is to lose an animal unexpectedly, but it will happen if you own livestock long enough. Some causes of mortality, such as predation, can be easily identified, but other causes are not as obvious. Certain diseases can prevent very few clinical signs, or strike before anything appears to be wrong. In this case, it is beneficial to take measures to protect the rest of your herd/flock.
Sudden loss of livestock is often chalked up as a loss and the carcass is disposed of or buried. When that happens, the cause is lost with the carcass. If it is not evident why that animal passed, having a necropsy performed will provide insight into the cause. The cause may be something like an infection, which is still good to know, or it could inform the producer of a much more serious issue (Avian Influenza, rabies, etc.). In the event of mortality, carcasses should be submitted for necropsy as soon as possible. Advanced decomposition will result in submissions being refused.
The North Carolina Department of Agriculture & Consumer Services has four diagnostic labs where necropsies can be performed. The closest location for our Orange and Durham County folks is the Rollins Lab in Raleigh (4400 Reedy Creek Rd
Raleigh, N.C. 27607). Other locations include Elkin, Monroe, and Fletcher. Prior to bringing a mortality to the lab, please call ahead. More information on these locations, their services, and associated forms.
