Conteúdo: | Early performance traits have been shown to be affected by both the lamb and the dam genotype. Lamb survival is more strongly influenced by lamb genotype than maternal genotype, in agreement with inferences from behavioural observations. Treating lamb survival as a trait of the lamb in selection indices will result in increased rates of genetic progress which are realised sooner. A genetic antagonism between lamb and maternal components of birth weight will limit increases in birth weight, and hence dystocia, if selection increases lamb growth rates.
