Abstract: | Genetic parameters were estimated in Large White and Landrace pigs for performance traits recorded under ad libitum and restricted feeding using electronic feeders in commercial conditions. Data included 3,950 records for ad libitum feeding and 3,275 records for restricted feeding. The level of restriction in feed intake was 11 %, which did not result in different heritabilities between feeding regimes, but reduced variance components for all performance traits under restricted feeding. The feeding regime did influence genetic correlations between performance traits. Selection for feed conversion ratio under ad libitum feeding will mainly reduce feed intake and only slightly increase growth rate. In contrast, selection for feed conversion ratio under restricted feeding will strongly increase growth rate but not reduce feed intake. Feed intake and feed conversion ratio were genetically different traits when recorded under different feeding regimes. | Publication Type: | Conference Publication | Conference Details: | AAABG 1999: 13th Conference of the Association for the Advancement of Animal Breeding and Genetics, Mandurah, Australia, 4th - 7th July, 1999 | Source of Publication: | Proceedings of the Association for the Advancement of Animal Breeding and Genetics, v.13, p. 142-145 | Publisher: | Association for the Advancement of Animal Breeding and Genetics (AAABG) | Place of Publication: | Armidale, Australia | ISSN: | 1328-3227 | Fields of Research (FoR) 2008: | 070201 Animal Breeding | Socio-Economic Objective (SEO) 2008: | 830308 Pigs | Peer Reviewed: | Yes | HERDC Category Description: | E1 Refereed Scholarly Conference Publication |
