The equation of Mould and Robbins (1982) was for white-tailed deer (Odocoileus virginianus). 2 Decumbent, evergreen variety. 70-- 60-- s 50-- Q O 40-- > 30-- 20-- Summer Winter. .oForbs & ferns .a Half-shrubs .a Shrubs q" .o Graminoids i A* // Forhs & ,o ferns AHalf-shrubs [j -•Conifers /' 48 0 , B Graminoids _j Conifers Shrubs Hours Hours 48 Figure 4.—Summer and winter values of 12- and 48-h in-vitro dry-matter digestibility (IDVMD) Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Hanley, Thomas A; McKendrick, Jay Dee, 1939-.
