Genetic correlations among carcass muscle dimensions (depth, width and area) and muscle weights (loin, topside and round) were positive and generally moderate to strong, as were genetic correlations among carcass fat traits (at the 5th rib, GR and C sites and weight of trimmed loin fat). The eye muscle dimensions had weak genetic correlations with the fat traits and bone weight, whereas the fat traits had favourable moderate to strong genetic correlations with topside and round weights, plus hind leg bone weight. Use of index selection in a simple terminal sire breeding program based on live animal traits is expected to yield improvements in most carcass composition traits. | Publication Type: | Conference Publication | Conference Details: | AAABG 2011: 19th Conference of the Association for the Advancement of Animal Breeding and Genetics, Perth, Australia, 19th - 21st July, 2011 | Source of Publication: | Proceedings of the Association for the Advancement of Animal Breeding and Genetics, v.19, p. 227-230 | 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: | 830310 Sheep - Meat 830311 Sheep - Wool |
