Simultaneous estimation of genetic parameters for production and litter size traits in Czech Large White and Czech Landrace pigs
Original language description
Genetic parameters for total number of piglets born per litter, number of piglets weaned per litter, lean meat content, and average daily gain from birth till the end of the field test were estimated for Czech Large White (445 589 records) and Czech Landrace (149 057 records) pigs using a four-trait animal model. The following heritabilities were estimated (first number: Large White, second number: Landrace): 0,10 ? 0,004 and 0,09 ? 0,007 for total number born, 0,09 ? 0,005 and 0,07 ? 0,008 for number weaned, 0,39 ? 0,004 and 0,36 ? 0,009 for lean meat content, 0,21 ? 0,004 and 0,18 ? 0,006 for daily gain. The highest genetic correlation (approximately 0,85 in both breeds) was estimated between both litter size traits. In Czech Landrace, all remaininggenetic correlations were < 0,20 in their absolute value. Negative correlations of approximately 0,25 were estimated in Czech Large White between daily gain and both reproduction traits. All remaining correlations in Czech Large White wer
