necropsy...........

A necropsy, also called a post-mortem exam, is an examination of an animal after death. It is performed to obtain an accurate cause of death, and when done properly involves looking at the animal as a whole, as well as looking at each individual organ within the body. Careful examination and sampling of organs helps determine the cause of death, whether it is by disease or trauma.

Why should I perform a necropsy?
Sometimes you may know why an animal has died, for example, there may be evidence of severe trauma. In other cases the clinical signs of a disease may indicate what happened to the animal. Most times, however, the nature and extent of the disease process may be unknown, or the symptoms could have been caused by one of several different diseases. In these cases it may be of great benefit to examine the animal more closely.
Reasons to necropsy an animal:

Identification of disease.
Indicate appropriate treatment of disease in a herd.
Limit future losses.
Improve understanding of disease effects on your animals.
Enhance discussion of health maintenance programs with animal health specialists.

When should I perform a necropsy? Changes in tissues occur as soon as 20 minutes after an animal has expired. Since these changes may obscure the true cause of death in an animal, it is important to sample tissues as soon after death as possible for an accurate diagnosis. This is particularly true if the weather is hot, the animal was febrile (had a fever), or when disease symptoms suggest involvement of the gastrointestinal (GI) tract. For these reasons it is important that the animal be examined as soon after the time of death as possible and tissue samples should be properly collected and thoroughly chilled until examination by a veterinarian.

Where should I perform a necropsy?

It is important that you keep biosecurity in mind when performing a necropsy. The best place to necropsy an animal is:

Away from other animals, food storage areas, and workers on the property.
An area that can be easily and thoroughly disinfected.
Easily accessible for the rendering truck to enter without having to drive through animal pens or feed areas.
Preferably it is a concrete pad, which can be cleaned fairly easily with a good disinfectant. If you have a concrete pad, try to work in an area that is rough. Smooth concrete may pose a safety hazard once it gets wet with water and/or blood.
If you do not have access to such a concrete pad, a dirt area would be the next best area. Like the pad, the dirt area should be away from other animals on the property and accessible for the rendering truck. Unlike concrete, the dirt area cannot be easily disinfected. For this reason it is best to have the area in direct sunlight because the heat and light will help kill many pathogens.

For both areas it may be beneficial to put up a fence, preferably one that is buried a few feet under ground. This will help to keep out wildlife that may serve as a vector for the spread of disease.
