Fig. 1From: Evaluation of direct and maternal responses in reproduction traits based on different selection strategies for postnatal piglet survival in a selection experimentDifferences in estimated breeding values between selected and control boars at mating and phenotypic selection responses of piglet survival during the nursing period estimated at the sow and piglet levels. Estimated breeding values (EBV) of Landrace and Large White boars at the time of mating were based on survival (SURV) and mortality (MOR) for maternal and direct effects, respectively. \({\text{H}}\) and \({\text{C}}\) represent high and control breeding groups and subscripts \({\text{D}}\) and \({\text{M}}\) denote direct and maternal genetic effects; *: significantly different from 0 (P < 0.05), ns: non-significantBack to article page
