“…The diet of roe deer analyzed in this study was dominated by plants of high nutritive value. In comparison to food acquired by roe deer in coniferous forests in other locations [59], it contained significantly more bramble, less dwarf shrubs and graminoids, and a similar share of forbs and coniferous browse. With respect to the food supply available in the study area [44], roe deer preferred bramble and dwarf shrubs and they avoided graminoids, tree leaves, and mosses.…”

“…In spite of significant differences in percentage share of particular types of food in the diets of fallow deer, red deer, and roe deer, 52.6% of the diet was common between all three species. Dietary overlap reached 70.4% between red deer and fallow deer, 59.7% between fallow deer and roe deer, 60.9% between roe deer and red deer (Figure 3). …”

“…However, contrary to the findings of other authors, we recorded a lower consumption of bramble, mushrooms, and crops, and greater consumption of fodder provided by hunters, as well as a lack of differences with respect to consumption of browse. However, it should be emphasised that food availability in a given environment has an important impact on the results [58,59].…”

The wild population of fallow deer in Central Europe has grown considerably over the last decade. However, information on feeding habits of this alien species in relation to the indigenous red deer or roe deer, in areas of their co-occurrence, is scarce. A prevailing view maintains that their food-niches are distinct, although direct comparative studies have not been carried out. Therefore, the aim of the research was to compare the diets of fallow, red, and roe deer feeding in the same habitat. Research was based on the rumen contents of 242 animals hunted in the autumn-winter season in the forests of Southern Poland. The analyses demonstrated that fallow deer are moderate grazers in such conditions and eat more graminoids in comparison to red or roe deer (36.4% vs. 16.1% or 5.5%, respectively). On the other hand, it feeds on less browse (17.2% vs. 41.4%) or dwarf shrubs (8.4% vs. 19.0%) than red deer, and on less bramble (10.9% vs. 34.6%) or forbs (4.0% vs. 7.6%) in comparison to roe deer (P=0.05). Although the diets of the three deer species differ in terms of the proportion of each food type in their diet, overlapping of their food-niches is high (52.6%).

“…Reports on the diet of free-ranging mouflon emphasize the importance of grass for this species (Mottl 1960, Tuercke and Schmincke 1965, Onderscheka and Jordan 1976, Hadjisterkotis 1996. In contrast, reports on the natural diet of roe deer confirm that this species consumes mainly browse and herbs, with grasses comprising only an annual average of about 5% of the diet (Cornelis et al 1999).…”

Seasonal faecal excretion, gut fill, liquid and particle marker retention in mouflon ovis ammon musimon, and a comparison with roe deer capreolus capreolus Seasonal faecal excretion, gut fill, liquid and particle marker retention in mouflon ovis ammon musimon, and a comparison with roe deer capreolus capreolus AbstractFive mouflon (average body mass [BM] 33 kg) and two roe deer (average BM 20 kg) with rumen cannulas were kept in large enclosures under semi-natural conditions and were used for seasonal studies on gastrointestinal tract (GIT) indigestible fill and digesta passage kinetics. As the mouflon were not fully mature, both species had similar digesta volumes in the reticulorumen (RR; mouflon 5.5 ± 1.8% of BM; roe deer 5.4 ± 1.5% of BM); however, the mouflon had lower RR liquid flow rates (15.1 ± 4.3 ml h-1 kg-0.75) than the roe deer (19.2 ± 0.2 ml h-1 kg-0.75), and particle retention in the RR accounted for 68 ± 3% of total GIT retention in the mouflon versus 55 ± 6% in the roe deer. Annual average total GIT retention times for liquids and particles were longer in the mouflon (23.4 ± 0.9 h and 37.9 ± 4.0 h) than in the roe deer (18.4 ± 1.7 h and 22.4 ± 1.9 h). Similarly, annual average RR retention times for liquids and particles were longer in the mouflon (11.9 ± 0.9 h and 25.8 ± 3.3 h) than in the roe deer (8.1 ± 1.7 h and 12.5 ± 2.3 h). The factor of selective particle retention in the RR (retention of particles/retention of liquid) was 2.10 ± 0.09 in the mouflon versus 1.54 ± 0.01 in the roe deer. These observations are in accord with differences in digesta passage characteristics postulated between browsing and grazing ruminants. Total GIT indigestible fill was lower in the mouflon than in the roe deer (10.7 ± 2.1 g kg-1 and 13.3 ± 1.0 g kg-1). As the mouflon were not fully mature, both species had similar digesta volumes in the reticulorumen (RR; mouflon 5.5 ± 1.8% of BM; roe deer 5.4 ± 1.5% of BM); however, the mouflon had lower RR liquid flow rates (15.1 ± 4.3 ml h -1 kg -0.75 ) than the roe deer (19.2 ± 0.2 ml h -1 kg -0.75 ), and particle retention in the RR accounted for 68 ± 3% of total GIT retention in the mouflon versus 55 ± 6% in the roe deer. Annual average total GIT retention times for liquids and particles were longer in the mouflon (23.4 ± 0.9 h and 37.9 ± 4.0 h) than in the roe deer (18.4 ± 1.7 h and 22.4 ± 1.9 h). Similarly, annual average RR retention times for liquids and particles were longer in the mouflon (11.9 ± 0.9 h and 25.8 ± 3.3 h) than in the roe deer (8.1 ± 1.7 h and 12.5 ± 2.3 h).

These observations are in accord with differences in digesta passage characteristics postulated between browsing and grazing ruminants. Total GIT indigestible fill was lower in the mouflon than in the roe deer (10.7 ± 2.1 g kg -1 and 13.3 ± 1.0 g kg -1 ).

“…The quantity and the quality of food resources diff er substantially in individual habitats and change o en during the year. It is the winter that is usually considered to be the most diffi cult season for large herbivores due to the shortage of quality food and due to the increased demands for energy spent on thermoregulation and movement (Kamler and Homolka, 2011;Mysterud et al, 2000;Cornelis et al, 1999). The requirements of herbivores are increased by the snow cover causing the movement more diffi cult and the food less accessible.…”

The botanical composition of red and roe deer and moufl on diet was studied in the mosaic landscape in Drahanská vrchovina highlands, Czech Republic. We focused on the proportion and quality of agricultural crops and natural forest plants and estimated quality of the herbivore diet. Diet quality was monitored by the near infrared refl ectance spectroscopy on the basis of nutritional quality of diet items. Red deer, roe deer and moufl on ingested all cultivated plants growing close to forest. However, the proportion of cultivated plants varied between seasons and herbivore species. The peak of crops consumption occurred in summer -when cereals spikes were ripe. The average proportion of corn for red deer was 40%. Cultivated plants were well accessible for herbivores in the study area and during vegetation period formed an important part of their diet, but the importance of cultivated plants for herbivores was lower compared with natural food resources present in forests during vegetation period. Although the main natural food sources had lower nutritional value, they formed the main part of herbivore diet in the study area. The availability of cultivated plants increases the quality of food supply during the growing season, but for herbivores the natural food sources are crucial, forming the main part of their diet both in summer and in winter. Wildlife management should reckon with feeding preferences of herbivores.
