IMPROVEMENT OF THE “TWO-POINT” METHOD FORMULA FORDETERMINING THE FLESHINESS OF PIG CARCASSES BASED ONOPTOELECTRONIC CHOIROMETER MEASUREMENTS

摘要

In the EU, the empirical relation used forrndetermination of the fleshiness of pig carcasses based onrnmeasured thickness of fat and muscle tissue in predeterminedrnmeasuring points is determined by prescribed procedure. Therndevices for measuring the thickness of fat and muscle tissue arernmainly optoelectronic or ultrasound devices. In RH anrnoptoelectronic device, ERO-1 has been developed according tornthe regulated technical and metrological demands valid in thernEU. The ERO-1 device is calibrated and its length-measuringrncapability is traceable to RH’s national standard. The datarngathered in measurements with ERO-1 devices (5 devices) overrna period of two years have made possible the improvement ofrnthe “two-point” method formula. We have developed a newrnempirical relation for determining the percentage of thernfleshiness of a pig carcass using the “two-point” method. Thernnewly developed empirical relation provides betterrnconcordance with biological characteristics of pigs populationrnand removes certain irregularities that were observed andrnrelated to the use of currently valid empirical relation employedrnwith verified and validated method of “two-points”, used in EUrnand other countries.
