The needs for roe deer in mineral matters and vitamins and process of their additional supply in the hunting fields

Abstract

An overview of physiological role of certain minerals and vitamins is given in the paper, and also the ways of their additional supply in our hunting fields. The size of roe deer’s requirements in minerals and vitamins varies throughout the year and depends on their age, sex, physiological state and other factors. The needs in minerals, first of all in calcium and phosphorus, are largest in lactating animals, than in the last third of pregnancy and in males when their antlers grow. Those needs are fulfilled form the natural feeds. However, for the maximal growth of antlers and obtaining of quality trophies the natural feeds may not be sufficient, which may happen in some years and in certain terrains. The requirements in micro elements and fat soluble vitamins are most successfully fulfilled when the mineral - vitamin premixes are included in concentrate mixtures, and with the use of salt blocks. .

U radu je dat pregled fiziološke uloge pojedinih mineralnih materija i vitamina, potrebe srna u mineralima i vitaminima, kao i postupci njihovog dopunskog snabdevanja u uslovima naših lovišta. Veličina potreba u mineralnim materijama i vitaminima varira u toku godine i zavisi od starosti grla, pola, fiziološkog stanja i drugih faktora. Potrebe u mineralnim elementima, pre svega kalcijumu i fosforu, najveće su u dojnih jedinki, zatim u zadnjoj trećini bremenitosti, kao i u mužjaka u periodu rasta rogova. Ove potrebe se zadovoljavaju iz prirodne hrane. Međutim, za maksimalan porast parogova i dobijanje kvalitetnih trofeja, prirodna hrana može biti nedovoljna, što dolazi do izražaja u nekim godinama i na nekim terenima. Potrebe u mikroelementima i liposolubilnim vitaminima najefikasnije se zadovoljavaju upotrebom mineralno-vitaminskih premiksa uključenih u smeše koncentrata, kao i upotrebom blokova soli za lizanje. .
