Farrowing Interval in Selection of Dam Pig Breeds in the Czech Republic

Popis výsledku v původním jazyce

The current total merit index (TMI) of dam breeds of pigs (Czech Large white and Czech Landrace) consist of average daily gain (ADG), number of piglets born alive (NBA) and lean meat content (LMC). Farrowing interval (FI) was included among breeding objectives and the selection criteria of TMI to enhance reproduction performance. Genetic end and economic response in complex of production, reproduction and carcass traits to selection on TMI was evaluated in the study. Current TMI gained high selection respond on piglets born alive (+0.31) with increase of ADG (+13.50 g) and keeping the LMC close to the current performance level (+0.02 %), all expressed per sow and per generation. Defining the FI as the breeding objective (leaving it omitted from the selection criterion) the trait value will be unfavourable increased by 0.07 day per sow and per generation. Direct incorporation of FI as the selection criterion would gain preservation of the length of interval (0.00 days per sow and per generation) with maintenance of the genetic and economic response in all other production and reproduction traits comparable with current TMI. Selection on current TMI caused correlated and not favoured response in the farrowing interval. Therefore, farrowing interval should be defined as the breeding objective and included among the selection criterion of the local dam pig breed population (thought TMI or a specialised reproduction index).
