Summary
Three Producer Demonstration Sites were undertaken in each of South Australia and Tasmania, to demonstrate the value of research breeding values for lean meat yield, intramuscular fat and shear force in prime lamb and Merino production systems.
Data was collected at slaughter from 527 Tasmanian lambs, over five slaughter events at either JBS Longford or JBS Devonport. Likewise, data was collected from 440 lambs from South Australian sites over five slaughter events at Thomas Foods International, Murray Bridge, JBS, Bordertown and Frewstal, Stawell.
Lean meat yield was calculated by measuring hot carcase weight (kg), GRfat (mm), Cfat (mm) and eye muscle area. Objective measures of eating quality were assessed by measuring fresh colour, ultimate pH, and shear force of the loin. Samples were collected and transported to the University of New England, Armidale, for intramuscular fat measurement.
Data collected from these PDS will be aggregated with data from other sites and analysed under the national coordination project, B.SCC.0144, to determine the value of research breeding values for lean meat yield and eating quality traits to ram breeders, lamb producers and processors.
