Description
Summary:An abstract of a study by Putz et al determining the genetic basis of resilience to multiple common diseases, which is defined as the ability to respond to infection to minimize the impact of disease is presented. Basic mixed models were fit with litter as a random effect as an indicator of the heritability due to the lack of pedigree and genotypes currently. Models for average daily gain in the nursery and in the finishing unit included fixed effects of batch, entry age (nursery only), days on test (finishing only), batch pen, and mortality (1/0) with litter as a random effect.
