1 st WorkshopXIII International Feed Technology SymposiumPRODUCTION OF FEEDS AND ADDITIONAL FEEDING OFGAME AS A MEASURE OF FOREST AND WILDLIFEPROTECTIONNenad Đorđević, Goran Grubić, Zoran Popović, Bojan Stojanović, Aleksa BožičkovićFaculty of agriculture, Nemanjina 6, 11080 Zemun, SerbiaABSTRACTDepending on the type of hunting ground and level of human activity, natural feedsources for game may be insufficient. When looking for food game may create variousdamages on crop, vegetable and fruit plantations, and also on domestic animals and bees.Natural feeding of game may be significantly improved with the amelioration of naturalpastures, production of fresh green forages within the hunting grounds and planting fruitand other trees which produce edible outgrowth. Direct supplemental feeding of game(with concentrates or forages) is done usually in the winter time, and is done mainly toprevent game mortality and improve their body mass and the quality of their trophies.The mentioned measures are of importance for herbivore and omnivore animals. Withthe supplemental feeding of carnivores the better control of animals is achieved(particularly of rare species), the migrations are reduced and the harmful effects ondomestic and other animals are reduced.Key words: game, hunting ground, feeds, damagesINTRODUCTIONIn our hunting grounds game animals may have various harmful effects, or may be atvarious risks. There are solutions for both cases, and they may be more or less successful(17).Damages that may be created by game on crops (maize, lucerne, wheat, barley, potatoand others) are generally less than 1%, and therefore may be considered as negligible(13, 18). The biggest damage is created by wild boars and ruminants, while birds may beharmful only in period when maize is in early growth (10, 11, 12). Total damage inforests and orchards (distraction of young plants and bark cutting) may occur in periodswhen natural feeds are deficient, or if the number of animals becomes too high for thesize of the hunting ground (25). That kind of damage is characteristic for hares and wildungulates (16). Special type of damage in agriculture and domestic animals in ourcountry is created by wolves and, rarely, other carnivores (24).With the appropriate management measures such damages may be reduced or preventedin the hunting grounds (21, 22, 23). One of the most important measures is to increasefeed production within the hunting ground, or supplemental feeding from other sourcesin times when damages occur (8).212
