Genetic parameters for number of piglets born alive using a random regression model



Genetic parameters for number of piglets born alive using a random regression model



Agriculturae Conspectus Scientificus Poljoprivredna Znanstvena Smotra 68(2): 105-108



A random regression model (RRM) was applied to estimate dispersion parameters for number of piglets born alive (NBA) from first to tenth parity. Random regressions on Legendre polynomials of standardized parity were included for common litter environmental, permanent environmental and additive genetic effects. Estimated phenotypic variance and variance components (ratios) for NBA changed over parities and differed between farms.
