(Elsevier, 2022-01-07)
In this study we used the phenotypic information of 1,499 Duroc pigs, recorded longitudinally in the age period from 110 to 200 days of age for individual daily feed intake (DFI), backfat thickness (BF) ...
Selection for feed efficiency using the social effects animal model in growing Duroc pigs: evaluation by simulation
(BMC, 2020-09-29)
Background
Traits recorded on animals that are raised in groups can be analysed with the social effects animal model (SAM). For multiple traits, this model specifies the genetic correlation structure ...
