Nowadays, both many scientists and breeders are interested in the possibilities of the substitution of allopathic medicinal products for animals by some natural alternatives, as plants products, prebiotics or probiotics. Jerusalem artichoke contains non-starch polysaccharide inulin, which can be used, because of its specific properties, as a natural prebiotic. The aim of this study was to incorporate Jerusalem artichoke tops to the feed mixture of growing rabbits as the natural source of inulin. 80 Hyla rabbits were randomly divided into 2 groups. The control group was fed standard diet, while Jerusalem artichoke group was given diet with 20% tops of Jerusalem artichoke. The experiment took place in commercial farm with standard conditions and was conducted as a preliminary examination, the growth performance and mortality of rabbits were observed. The diet with 20% tops of Jerusalem artichoke decreased feed conversion ratio about 0.39 (11%) and the mortality of rabbits about 10% (P<0.05) compared with control group. Jerusalem artichoke tops (20%) may be incorporated to rabbit diets as an appropriate source of carbohydrates with prebiotic properties for growing rabbits and thus may partly replaces some ingredients (starch sources), which burden the not completely developed digestive system of young animals. Keywords: growth performance, inulin, Jerusalem artichoke, mortality, prebiotics, rabbits V soucasnosti se rada vedcu i chovatelu zajima o moznosti nahrady alopatickych leciv urcenych pro zvirata nekterymi pfirodnimi alternativami jako jsou rostlinne preparaty, prebiotika a probiotika. Topinambur hliznaty obsahuje neskrobovy polysacharid inulin, ktery muze byt, diky jeho specifickym vlastnostem, vyuzit jako prirodni prebiotikum. Cilem teto studie bylo zaclenit nat'topinamburu hliznateho, jako prirodni zdroj inulinu, do krmne smesi rostoucich kraliku. 80 Hyla kraliku bylo nahodne rozdeleno do 2 skupin. Kontrolni skupina byla krmena standardni krmnou smesi, zatimco skupine "topinambur hliznaty" byla podavana smes s 20% nati topinamburu hliznateho. Pokus byl uskutecnen ve standardnich podminkach komercni farmy a slouzi jako predbezny vyzkum, sledovana byla vykrmnost a mortalita kraliku. Krmna smes obsahujici 20% nati topinamburu hlfznateho ve srovnani s kontrolni snizila konverzi krmiva o 0,39 (11%) a mortalitu kralfku o 10% (P<0,05). Nat' topinamburu hlfznateho (20 %) je mozne zafadit do krmne smesi kraliku jako vhodny zdroj karbohydratu s probiotickymi vlastnostmi pro rostoucf kralfky, a tim nahradit nektere jeji slozky (zdroje skrobu) zatezujici neuplne vyvinuty travicf system mladych zvirat.
