  • Title: Variation among beef breeds in carcass retail value at constant carcass saleable meat content and percentage of higher priced cuts.
    Author: Kempster AJ, Cook GL.
    Journal: Meat Sci; 1983; 9(4):281-90. PubMed ID: 22055925.
    Abstract:
    Data from the single slaughter point trials of the Meat and Livestock Commission's (MLC) beef breed evaluation programme were used to examine the importance of retail value (RV) calculation in breed evaluation trials. The analysis involved a total of 2010 carcasses comprising four production system groups. Sire breeds included Aberdeen-Angus, British Friesian, Charolais, Devon, Hereford, Galloway, Limousin, Lincoln Red, Luing, Simmental, South Devon, Sussex and Welsh Black. RV was computed as the sum of the values of trimmed deboned primal joints expressed as pence per kilogram of carcass weight. 1981 prices from MLC's Retail Prices Survey for England and Wales were used. A model was fitted to the RV data for each of the production system groups with effects for sire breed, year and sire breed × year interaction, and with regression on saleable meat percentage in carcass (SM). The largest difference recorded between sire breeds was 2·1 pence/kg (0·85% of overall mean RV). The pooled within-system residual standard deviation after fitting the model was 1·4 pence/kg. When regression on the percentage of total saleable meat in the higher priced cuts (SMD) was added to the model, the corresponding range and residual standard deviation were reduced to 1·0 and 0·8 pence/kg, respectively. In the circumstances, the calculation of RV would, therefore, make only a minor refinement to the results.
