Genetic parameters for lean meat yield, meat quality, reproduction and feed efficiency traits for Australian pigs 2. Genetic relationships between production, carcase and meat quality traits
Data from 1799 Large White and 1522 Landrace boars were used to obtain genetic correlations between production, carcase and meat quality traits. Variance components were obtained by REML procedures applying an average information algorithm. Traits analysed included average daily gain from 3 to 18 weeks of age (ADG1) and average daily gain, feed intake and feed conversion ratio from 18 to 22 wee...
متن کاملEstimation of Genetic Associations between Production and Meat Quality Traits in Duroc Pigs
Data collected from 690 purebred Duroc pigs from 2009 to 2012 were used to estimate the heritability, and genetic and phenotypic correlations between production and meat quality traits. Variance components were obtained through the restricted maximum likelihood procedure using Wombat and SAS version 9.0. Animals were raised under the same management in five different breeding farms. The average...
متن کاملGenetic parameters for lean meat yield, meat quality, reproduction and feed efficiency traits for Australian pigs 3. Genetic parameters for reproduction traits and genetic correlations with production, carcase and meat quality traits
Genetic parameters were obtained using REML procedures applied to a multiple trait animal model for number born alive (NBA), litter birth weight (LBW), average piglet weight at birth (ABW) recorded in the first, second and third parity (NBA , LBW , ABW ) and 21-day litter weight (LW21 ) for 6050 Large White and Landrace sows. Heritability 1,2,3 1,2,3 1,2,3 1 estimates ranged from 0.06 to 0.22 f...
متن کاملImmunity Traits in Pigs: Substantial Genetic Variation and Limited Covariation
BACKGROUND Increasing robustness via improvement of resistance to pathogens is a major selection objective in livestock breeding. As resistance traits are difficult or impossible to measure directly, potential indirect criteria are measures of immune traits (ITs). Our underlying hypothesis is that levels of ITs with no focus on specific pathogens define an individual's immunocompetence and thus...
