Description
  • V populaci prasat s vysokým podílem importovaných genů byla zkoumána selekce mladých zvířat v různých časových periodách (založená na postupném zvyšování údajů a rozšiřování matice příbuznosti). Předpokládalo se, že optimální model pro výběr nejlepších jedinců je model s genetickými skupinami, který zohledňuje rozdílnou genetickou úroveň domácích a importovaných zvířat. Cílem studie bylo zjistit možnou selekční ztrátu při používání současného modelu, který genetické skupiny nezohledňuje. Předpověď selekční efektivnosti a selekční ztráty byl založen na stanovené celkové plemenné hodnotě selektovaných jedinců (mladých kanců po ukončení polního testu) vyjádřené v penězích. Byla použita různá intenzita selekce (10, 20 a 50%). (cs)
  • Selection of young animals in different time periods (based on sequentially increasing data and pedigree files) was investigated in a pig population with a high proportion of imported genetics. The model with genetic groups accounting for different genetic levels of native and imported animals was assumed to be the correct one for selecting the best animals. The objective of this study was to estimate the possible selection loss when the selection decision was based on the commonly used model not accounting for different genetic groups. The prediction of the selection efficiency and selection loss was based on the monetary total breeding value of the selected animals ? young boars after finishing the field test. Different selection intensities were applied (10%, 20% and 50% respectively).
