Nowadays breeding has become the problem often solved in European states and it has been paid much attention by breeding organizations. In terms of hippology as well as some urgent requirements from the side of nonius breeders we have focussed on this particular breed especially from the reason of its further survival and development in Slovakia. The aim of this paper was to evaluate the growth indicators as well as the achievement level of the stallions since 1927 to the present. Based on our research of the nonius body lines we can state that at present there are 3 stallions that are followers of the N VIII horse line founder. In general, there are 12 stallions that are active within this breed in Slovakia. It was statistically confirmed that this particular breed grew much stronger through the goal-directed breeding work, improved nutrition as well as the immediate breeding site. It was quite complicated to evaluate the performance tests because the individual indicators were significantly influenced by the subjective views of the commitee members performing the evaluation. The next factor which prevents the objective evaluation is the fact that in the period up to 1979, the performance tests were valued by the 100 point system and from the year 1980 by the 10 point system. That is why we take the performance test results into account only as supplemental ones, which can provide a kind of amendment to the observed biological parameters.

Šľachtenie je v európskych štátoch v súčasnosti často riešený problém a chovateľské organizácie mu venujú veľkú pozornosť. Preto sme sa z hľadiska rozvoja hipológie, ale zároveň z hľadiska veľkej potreby chovateľov plemena nonius, venovali tomuto plemenu s ohľadom na jeho pretrvanie a ďalší rozvoj na Slovensku. Cieľom práce bolo vyhodnotiť vývoj rastových ukazovateľov a výkonnostnú úroveň žrebcov od roku 1927 do súčasnosti Na základe skúmania jednotlivých línií noniusa môžeme konštatovať, že po zakladateľovi línie N VIII pôsobia v súčasnosti v plemenitbe 3 žrebce. Celkovo v rámci tohto plemena pôsobí na Slovensku 12 žrebcov. Cielenou šľachtiteľskou prácou, zlepšenou výživou a chovateľským prostredím dochádzalo k zmohutneniu jedincov tohto plemena, čo bolo štatisticky potvrdené. Hodnotenie výkonnostných skúšok bolo pomerne komplikované, pretože jednotlivé ukazovatele mohli byť významne ovplyvňované subjektívnym pohľadom hodnotiacich členov komisie. Ďalším faktorom, ktorý zamedzuje objektívne hodnotenie, je skutočnosť, že v období do roku 1979 boli výkonnostné skúšky hodnotené 100 bodovým systémom a od roku 1980 10 bodovým systémom. Preto výsledky z výkonnostných skúšok berieme do úvahy len ako doplnkové, ktoré môžu dokresľovať sledované biologické parametre. [ABSTRACT FROM AUTHOR]
