Abstract: Breeding and geneticsFull-length research article Genetic study of litter size and litter uniformity in Landrace pigs ABSTRACT -We aimed to estimate litter size and litter uniformity genetic parameters and genetic trends of Landrace pigs at birth and at three weeks by using multitrait analyses for 2,787 litters. The following litter traits were evaluated: number of piglets born alive (NBA), within-litter weight mean at birth (MBW), within-litter weight standard deviation at birth (SDB), within-litter weight co… Show more

“…(2006) estimated the phenotypic correlations of NBA to be 0.928 with LWB and –0.446 with MWB in mice originated from a three‐way cross of three inbred straits (Balb/c, C57BL, and CBA). Previous studies in pigs also estimated positive phenotypic correlations between NBA and LWB and negative phenotypic correlation between NBA and MWB (Banville et al., 2014; Bergsma et al., 2008; Camargo et al., 2020; Kapell et al., 2011; Matheson et al., 2018; Ogawa et al., 2019a; Wolf et al., 2008; Zhang et al., 2016). Correlations of NBA with MaxIWB and MinIWB were weakly negative and that with Range was weakly positive, in agreement with Wolf et al.…”

“…However, the standard errors were not small. Most previous studies in pig estimated the genetic correlation between NBA and SDIWB to be positive (Banville et al., 2014; Camargo et al., 2020; Damgaard et al., 2003; Kapell et al., 2011; Matheson et al., 2018; Wolf et al., 2008). Wolf et al.…”
