Genomic selection for maternal traits in pigs.
The aim of this study was to compare alternative designs for implementation of genomic selection to improve maternal traits in pigs, with a conventional breeding scheme and a progeny testing scheme. The comparison was done through stochastic simulation of a pig population. It was assumed that selection was performed based on a trait that could be measured on females after the first litter, with...
متن کاملGenomic selection for feed efficiency traits
Introduction Feed costs comprise the majority of variable expenses in beef cattle systems making feed efficiency an important economic consideration within the beef industry (Koch et al ., 1963; Dickerson et al ., 1974) . Aside from the direct economic impact of this trait complex at the individual producer level, the projections of global population growth provide extra pressure for efficient ...
متن کاملEffects of selection for ultrasound intramuscular fat percentage in Angus bulls on carcass traits of progeny.
Angus bulls (n = 20) from three pure-bred herds in Georgia were acquired to determine the impact of selecting sires based on phenotypic yearling ultrasound intramuscular fat percentage (UIMF) or UIMF EPD on marbling score of steer progeny. Each year in each herd, pairs of bulls were selected to create large differences based on their age adjusted phenotypic yearling UIMF measurements. The avera...
متن کاملGenomic selection : the option for new robustness traits ?
20 Genomic selection is rapidly becoming the state-of-the-art genetic selection 21 methodology in dairy cattle breeding schemes around the world. The objective of this 22 paper was to explore possibilities to apply genomic selection for traits related to dairy 23 cow robustness. Deterministic simulations indicate that replacing progeny testing with 24 genomic selection may favour genetic respon...
متن کاملGENOMIC SELECTION Parametric and Nonparametric Statistical Methods for Genomic Selection of Traits with Additive and Epistatic Genetic Architectures
Parametric and nonparametric methods have been developed for purposes of predicting phenotypes. These methods are based on retrospective analyses of empirical data consisting of genotypic and phenotypic scores. Recent reports have indicated that parametric methods are unable to predict phenotypes of traits with known epistatic genetic architectures. Herein, we review parametric methods includin...
