“…In the average roe-deer weighing approximately 20 kg such amount of fat corresponds to approximately 10,000 kcal. Drożdż & Osiecki (1973) studied in roe-deer the consumption and digestibility of natural food in the winter period and found a poor digestibility of browse in this period. Assuming that no other food is then available, the daily deficite of energy consumption may reach 400 kcal.…”

“…The data on their energy metabolism are totally lacking, while the investigations on consumption and digestibility of natural food in this species were carried out in a rather narrow scope (Drożdż & Osiecki, 1973;Drożdż et al, 1975; E i s f e 1 d, 1974;Ellenberg, 1974). Energy metabolism was studied only in a few species of American deer, red deer and reindeer {e.g.…”

Weiner J., 1977: Energy metabolism of the roe deer. Acta theriol., 22, 1: 3-24 [With 5 Tables & 9 Figs.].Energy metabolism of the roe deer Capreolus capreolus (Linnaeus, 1758) was investigated by means of the respirometric method. The level of metabolism in roe deer is similar to that of other wild ruminants but higher than the mean interspecies metabolism of mammals. Fasting heat production (FHP) shows seasonal variations, being the highest during spring molting season, slightly lower in summer and the lowest in winter: 117.0, 99.4 and 91.3 kcalXkg-o-^Xday-i, respectively. In spring and summer the metabolism increases at lower temperatures: FHP (kcalXkg -0 -75 Xday-i) = 181.5-5.32 t (where t=°C). Resting metabolism of non-fasted animals (RHP) is higher than FHP by 25-30%, and this difference represents the specific dynamic action of food (SDA). Motoric activity causes a rise of metabolism by 9-210°/o, the cost of maintaining of upright position being equal to 1.1 kcalXkg -0 -75 X Xhr-i. Resting metabolism of fawns up to 80 days of life is linearly correlated with their body weight (W, kg): RHP = 73.53W (where RHP = =kcalX animal -1 X day -1 ). RHP reaches the highest values on 7th day of life. In fawns 6 to 8 month old FHP amounts to 109.9 kcalXkg -°-7 5 X Xday -1 , and RHP is higher by 22%. The mean respiratory quotient (R.Q.) was equal to 0.82; the lowest values (0.79) were observed in fasting and resting animals, while the highest (0.86) in active nonfasting ones.

“…Thus, is attained decidedly higher values than 70-102 kcal/kg 0 75 X day given by Drożdż & Osiecki (1973). The main cause of such great divergencies is the varied composition of the diets tested in the studies mentioned.…”

1Kajetan PERZANOWSKI Perzanowski K., 1978: The effect of winter food composition on roedeer energy budget. Acta theriol., 23,.In order to establish relationships between the composition of natural food and the energy budget of the roe-deer (Capreolus capreolus L.), a number of feeding experiments were carried out with mixed diets consisting of various proportions of browse and plants of forest herb layer. The consumption of these kinds of foods ranged from about 30 g dry matter/animal X day as regards young shoots of alder buckthorn (Frangula alnus) to more than 550 g dry matter/animal X day in the case of herbs. The dry matter digestion coefficient appeared to be highly correlated with the herb content in the food. A similar relationship existed between the intake of digestible energy, ranging from 36 to 242 kcal/kg body weight 0 -7 5 X day, and the food composition. It was computed that in the winter the roe-deer, keeping its energy budget balanced, takes food containing more than 50% herbaceous plants, whose digestibility coefficient exceeds 60%. Distinct relationships were found between the food composition and the digestibility of the following fractions: Cell Wall Content (CWC), Cell Content (CC), Acid Detergent Fiber (ADF) and Acid Detergent Lignin (ADL). The equation of multiple regression, describing the relationship between the digestibility of food and the content of CWC, ADF and ADL fractions in it, was also calculated.
