Abstract: Genetic correlations were estimated among lamb carcass composition traits recorded on progeny of the Information Nucleus program of the CRC for Sheep Industry Innovation. 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.
