Six new markers (UMNP885, UMNP1049, UMNP875, UMNP925, UMNP876 and UMNP519) were linkage mapped to porcine chromosome 10 for the first time. Phenotypes were available for juvenile IGF-I along with feed intake, average daily gain and feed conversion ratio (FCR) recorded over a 6 week performance test period; associations between QTL and residuals for these traits were investigated. A significant QTL for FCR was found between marker UMNP875 and UMNP925 by single family and across family analysis with maximum likelihood using composite interval mapping, confirmed by linkage disequilibrum and linkage analysis (LDLA). In single family analyses, a significant QTL for average daily gain was found in sire family 896TS and an IGF-I QTL was found in sire family 52103. The study provided strong justification for further fine mapping and positional cloning of causative genes for FCR on chromosome 10 for marker assisted selection in pig breeding. | Publication Type: | Conference Publication | Conference Name: | 18th Conference of the Association for the Advancement of Animal Breeding and Genetics, Barossa Valley, Australia, 27th September - 1st October, 2009 | Conference Details: | 18th Conference of the Association for the Advancement of Animal Breeding and Genetics, Barossa Valley, Australia, 27th September - 1st October, 2009 | Source of Publication: | Proceedings of the 18th Conference of the Association for the Advancement of Animal Breeding and Genetics: Matching Genetics and Environment - a New Look at an Old Topic, p. 183-186 | Publisher: | AAABG: Association for the Advancement of Animal Breeding and Genetics | Place of Publication: | Taringa, Australia | ISSN: | 1328-3227 | Field of Research (FOR): | 070202 Animal Growth and Development 070201 Animal Breeding |
