Description
| - The effect of the PvuII polymorphism of the oestrogen receptor gene on litter size and production traits in a Czech Large White population was evaluated with four-trait animal models. The traits analyzed were lifetime average daily gain in the field test, lean meat percentage, number of piglets born alive in 1st litter and in 2nd and later litters. The animal models differed in considering the herd-year-season effect as random or fixed and in including or not including the dominance effect. On the genetic level, no significant overall effects of the ESR gene were detected. The effects of the ESR gene within herds were mostly nonsignificant as well. There was a certain tendency for allele A to increase litter size in 1st litter. Nevertheless on the basis of the present knowledge, the use of the ESR gene for selection on litter size in the Czech Large White breed seems to be of questionable benefit and cannot be recommended.

- Efekt PvuII polymor.smu genu estrogenového receptoru (ESR) na velikost vrhu a produkční znaky byl vyhodnocován v deseti chovech plemene bílé ušlechtilé (882 plemenic, 2455 vrhů) v České republice. K analýze vlastností průměrný denní přírůstek od narození, podíl libového masa, počet živě narozených selat na prvních vrzích a počet živě narozených selat na druhých a dalších vrzích byly využity čtyři čtyřznakové animal modely. Jednotlivé animal modely se lišily typem efektu stádo-rok-období (pevný nebo náhodný) a zahrnutím nebo nezahrnutím dominantního efektu. Efekty ESR byly hodnoceny jak v rámci jednotlivých chovů, tak i přes chovy. Při vyhodnocování přes chovy nebyly na genetické úrovni zjištěny průkazné efekty ESR na žádnou z hodnocených vlastností, efekty ESR v rámci chovů byly také převážně neprůkazné. Na prvních vrzích byla patrná tendence k vyšší užitkovosti spojené s alelou A. Nicméně při současné úrovni znalostí nelze využití ESR pro selekci na velikost vrhu jednoznačně doporučit. (cs)
