Quick Answer
Assess deer health by examining its body condition, observing its behavior, and checking for visible signs of disease or injury. Look for a plump, well-muscled deer with a shiny coat and a healthy demeanor. A deer in poor condition may be better left unharvested.
Visual Inspection
When assessing deer health, begin by visually inspecting the animal from a safe distance. Look for signs of disease or injury, such as open sores, abscesses, or unusual growths. Check the deer’s body condition by observing its muscle mass, fat reserves, and overall appearance. In Michigan, a healthy whitetail deer typically has a body condition score of 4 or 5 on a 5-point scale, with a score of 5 indicating optimal condition. This can be visually estimated by checking the deer’s ribcage, hip bones, and other bony structures.
Behavioral Observations
Next, observe the deer’s behavior to gauge its overall health and well-being. A healthy deer will exhibit normal behaviors, such as feeding, drinking, and interacting with other deer. Look for signs of stress or abnormal behavior, such as pacing, vomiting, or lethargy. In Michigan, deer that are stressed or sick may tend to avoid areas with high human activity, such as roads and trails.
Physical Examination
If possible, conduct a physical examination of the deer to gather more information about its health. This can be done by checking the deer’s vital signs, such as its heart rate, breathing rate, and temperature. Look for signs of disease or injury, such as swelling, inflammation, or bleeding. In Michigan, deer may carry diseases such as chronic wasting disease (CWD) or tuberculosis, which can be transmitted through contact with infected deer. A physical examination can help identify these diseases and inform your decision about whether to harvest the deer.
