Effects of Supplemental Ryegrass Versus Subterranean Clover on Fawn Weight

White-tailed deer (Odocoileus virginianus) fawns were fed calf-creep feed (12% crude protein) ad libitum in pens where either ryegrass (Lolium multiflorum) or subterranean clover (Trifolium subterraneum) was planted for winter feed. During a 143-day period (29 Nov 1984-21 Mar 1985) fawns in the pen with ryegrass gained (x ± SE) 9.65 ± 2.4 kg/fawn while those in the pen with subterranean clover gained an average of 18.8 ± 2.5 kg/fawn. Differences were significant (P < 0.10) and were not influenced by sex. Use of calf creep feed per deer was not significantly different between the 2 treatments.
