Quick Answer
Chronic wasting disease (CWD) in elk and deer presents similar symptoms, including weight loss, lethargy, and progressive loss of coordination. However, elk tend to exhibit a more pronounced emaciation and a higher degree of behavioral changes. Elk with CWD may also display a more erratic movement pattern.
Early Detection of CWD in Elk
The first visible signs of CWD in elk can be observed in the early stages of the disease, typically 12-18 months after infection. These include a gradual decline in body condition, leading to weight loss and a decrease in muscle mass. A pronounced loss of fat reserves around the neck and shoulders is often noticeable. In some cases, elk may display a more nervous or agitated behavior, such as increased pacing or restlessness.
CWD Progression in Elk
As CWD progresses, elk may exhibit significant weight loss, often exceeding 30% of their initial body weight. This can lead to a pronounced emaciation, making the animal appear gaunt and skeletal. In addition, the animal’s coat may become dull and matted, and its eyes may take on a sunken appearance. In the later stages of the disease, elk may display a complete loss of coordination, with difficulty standing or walking.
Field Identification Techniques
To aid in field identification of CWD in elk, hunters can look for specific signs, such as the presence of abnormal, uncoordinated movement patterns or a failure to respond to external stimuli. In addition, hunters can examine the animal’s body condition, looking for evidence of significant weight loss or emaciation. A thorough examination of the animal’s brain and lymph nodes can also provide valuable information for post-mortem diagnosis of CWD.
