Effect of boars own performance on progeny fattening and carcass traits in two different environments
Bahelka I., Fľak P., Lukáčová Anna
The effect of own performance traits of meat breed boars on fattening and carcass parameters of progeny in two different test stations (Bučany and Nitra) was evaluated. Own performance traits of boars were average daily gain (ADG) from birth to 100 kg live weight, backfat thickness (BF) and lean meat content (LMC) in field conditions. Progeny of boars was housed in pairs (gilt and barrow) and fed standardized feed mixture semi ad libitum. Progeny test lasted from 30 to 100 kg live weight. There were evaluated following parameters: ADG and feed consumption/kg gain (FC) at test from 30 to 100 kg live weight, slaughter weight (SW), proportion of meaty cuts (PMC) proportion of ham (PHAM), eye muscle area (EMA), and BF. At Bučany and Nitra was found the effect of genotype of boars on progeny BF and/or FC respectively. Better tested boars from own performance test individually as well as a group achieved in progeny better fattening and carcass traits than worse tested boars at Bučany (+33 g ADG, -0.21 cm BF, +2.34 % PMC). Progeny performance from better evaluated boars at Nitra did not exceed the progeny performance from worse tested boars. There was found significant effect of dams on progeny performance.
