White-tailed Deer Browsing

1-10-18 white-tailed deer eating hemlock 049A1922Microorganisms inside a deer’s four-chambered stomach enable cellulose in the plant material consumed to be digested. In winter, the microorganisms within the deer stomach are different from the microorganisms in spring, summer, and fall. This change allows deer to digest a diet of woody browse during winter months and turn the high-fiber diet into proteins through intricate physiological processes. Among their preferred browse are White Cedar, Yew, American Basswood, Alternate-leaved and Flowering Dogwood, Maples, Staghorn Sumac and Witch Hobble.

Offering food items during this period other than woody browse (such as hay) is detrimental to deer, as it requires different microorganisms in the stomach in order to be digested. Thus, even though a deer’s stomach might be full (of hay, for instance), it may starve due to the inability to digest it.   (Photo: White-tailed Deer browsing on Eastern Hemlock)
