    Growth and carcass value of original pig populations evaluated by in vivo and post mortem methods

  • Original language description

    At a pig progeny testing station growth and production traits were examined in 38 pigs (20 animals of Large White /LW/ breed, 18 animals of Large White breed - paternal line /LWp/) using methodical instructions for performance testing and testing of purebred progeny. Richards function was applied to calculate the parameters and characteristics of growth curves that document a change in the production type of both breeds towards a markedly meat type in the course of 10 years. The changes were reflected in an increase in the lean content on average by 3% in LW breed and by 2.7% in LWp breed. This positive trend is documented by the results measured by in vivo and post mortem methods. Both groups of methods of measuring lean percentage provided a good coincidence of the results; therefore the instrument SONOMARK-100 can be recommended for an early estimation of breeding value in growing pigs.

    Růst a jatečná hodnota výchozích populací prasat posuzovaná metodami in vivo a post mortem

  • Czech description

    Na testační stanici prasat byl sledován růst a produkční znaky 38 ks zvířat (20 ks plemene BU, 18 ks plemene BO) na základě metodik pro hodnocení vlastní užitkovosti a testaci čistokrevného potomstva. Pomocí Richardsovy funkce byly vypočteny parametry acharakteristiky růstových křivek, které dokládají změnu užitkového typu obou plemen v průběhu 10 let k typu výrazně masnému. Změny se odrazily ve zvýšení podílu svaloviny v průměru u BU o 3 % a u BO o 2,7 %.Tento pozitivní trend dokládají výsledky zjištěné in vivo a post mortem metodami. Obě skupiny metod zjišťování podílu svaloviny vykazovaly dobrou shodu, a proto lze doporučit využití přístroje SONOMARK k časnému odhadu plemenné hodnoty rostoucích zvířat.
