Název v původním jazyce

Use of BIA method for the estimation of beef carcass composition - weight of longissimus lumborum muscle, ratio of muscle tissue and fat in loin cross-section

Popis výsledku v původním jazyce

Bioelectrical impedance analysis was tested on 54 beef carcasses for prediction of their composition - weight of longissimus lumborum muscle, ratio of muscle tissue and fat in the cross-section of loin. A four-electrode method of measurement with flat elastic electrodes coated with Cu-foil of the surface area about 30 cm2 was used for measurements of BIA. To use a bioimpedance analyzer, developed for measurements of resistance and reactance at frequencies of 1 kHz, 10 kHz and 100 kHz, as a fully automatic measuring system for on-line measurements on slaughter lines, it was connected to PC. Relatively high correlations were found between longissimus lumborum muscle weight (MLL) and BIA values. Specific values of resistance (100Rp/D) and reactance (100Xcp/D) measured at frequencies of 100 kHz show a high correlation r = 0.907 and r = 0.906, so they are good predictors for the estimation of this muscle weight. The variables derived from reactance 100Xcp (100Xcp/L #r = 0.816 and 100Xcp#. r
