Prediction of commercial classification values of beef carcasses by means of the bioelectrical impedance analysis (BIA).

Popis výsledku v původním jazyce

The objective of the experiment was to determine the precision of the prediction of commercial classification values (conformation and fatness) of beef carcasses by means of the bioelectrical impedance analysis (BIA). The method was applied on 441 carcasses using an automatic measuring system with flat elastic electrodes with the surface area of 30 cm2 located on the outside of the left half-carcass. Resistance and reactance at two frequencies, i.e. 1 kHz and 100 kHz, were registered. A number of impedance values show significant correlations to the conformation of the carcass. Among all evaluated categories, the strongest correlation (r = 0.86) was found between conformation and the value D2/Xcp100k (relationship between the square of the distance between electrodes and the calculated parallel reactance at 100 kHz). Significant relations were also identified for fatness, particularly in the females. The highest correlations were found in values derived from the calculated parallel rea
