Estimation of sire with feeding regime interaction in pigs

Extract
Genetic improvement in commercially important traits of pigs produced under commercial conditions is generally achieved through selection of parents which are performance tested under special conditions. If pigs are performance tested in one environment and progeny tested in another environment, then the same animals may not be selected on the basis of the two tests, which would result in a genotype-environment interaction. The testing station and commercial unit often have feeding regime (ad-libitum, restricted or both) confounded with environment. This study estimated the genetic correlation between ad-libitum and restricted feeding in one environment for production traits to traits to determine the contribution 6T the genotype-feeding regime interaction to the genotype-environment interaction.
