Sustaining Values of Emergency Foods for Bobwhites

摘要: Sustaining values of foods that might be useful to bobwhites (Colinus virginianus) under emergency conditions were tested by feeding penned single during fall and winter observing their survival condition. In the pilot study, 11 for 38 days; 132 mixed sex age-groups employed. principal 6 these 14 days on 84 young birds both sexes. On basis food consumption, weight performance, depot fat, lipid levels, other physiological measures, pearl millet (Pennisetum glaucum), sassafras (Sassafras albidum), foxtail (Setaria italica), milo (Sorgum vulgare) had highest sustaining among tested. Their exceeded those such well- known staples as corn (Zea mays) Korean lespedeza (Lespedeza stipulacea). Sericea cuneata), rose (Rosa multiflora) hips, smooth sumac (Rhus glabra) ranked lowest.
