Genetic parameters for reproduction traits in sows of lines selected for growth rate on restricted feeding



Genetic parameters for reproduction traits in sows of lines selected for growth rate on restricted feeding



50 years of DNA: Proceedings of the Fifteenth Conference, Association for the Advancement of Animal Breeding and Genetics, Melbourne, Australia, 7-11 July 2003: 245-248



Genetic parameters for litter traits: total number born (TNB), number born alive (NBA), average piglet birth weight (ABW) and number of piglets weaned (NW), and for sow traits: mating weight (MW), gestation length (GL) and daily food intake of lactating sows (DFI), were estimated on 913 litter records through the restricted maximum likelihood method using an animal model. Estimates of heritability for most of the traits except for ABW (0.33) and MW (0.32) were low, around 0.10.
