Palatabilidad y composición química de alimentos consumidos en cautiverio por el venado cola blanca de Yucatán (Odocoileus virginianus yucatanensis) Palatability and chemical composition of feeds ingested in captivity by Yucatan white-tailed deer (Odocoileus virginianus yucatanensis)

摘要: SUMMARY The study was conducted at the Regional University Center located in Temozon, north of Yucatan (Mexico). dietary preferences 10 white tailed deer (Odocoileus virginianus) subspecies yucatanensis were estimated selection eleven plants growing state Yucatan, using a cafeteria type. chemical composition and vitro dry matter digestibility (IVDMD) diet different vegetal species determined, as well nutritional balance (30.2±2.65 kg BW) fed with those species. selected mainly arboreal ones (76.52%), smaller proportion forbs (19.37%), herbaceous (5.81%) minimum graminae (0.29%). legumes Leucaena leucocephala Brosimum alicastrum constituted 51.20% ration. had 56.97% matter, 17.64% crude protein, 42.53% cell walls an IVDMD 56.90%. results multiple linear regression analyses showed that have significant impact (P 0.1), it presented correlation (r = 0.23; P < 0.05), none other nutrients or effect on feed intake. When evaluated within same analysis, positive 0.0012) whereas tended 0.11) to reduce intake quadratically. It ration meets maintenance requirements nitrogen energy excess, allowing maximum 30% increase for activity over basal metabolism, reason why vegetation can be considered nutritionally excellent due its protein content deer.
