THE GAIN AND PER CENT CONTENT OF THE MEAT INTENDED FOR PROCESSING, AND OF THE CULINARY ELEMENTS FROM THE TRIMMING OF CARCASSES DIFFERENTIATED BY HOT CARCASS WEIGHT AND CLASS OF LEANNESS ACCORDING TO THE EUROP CARCASS GRADING SYSTEM

S u m m a r y

The objective of this paper was to determine the effect of hot carcass weight and leanness according to the EUROP carcass grading system on the gain and per cent content of culinary elements and meat intended for processing obtained from the trimming of primal cuts. The investigations were performed in March 2001, on 100 fatteners from the mass population, and originating from a raw meat facility belonging to one meat plant located in central-eastern Poland. The carcasses were selected directly on the slaughter line according to the three criteria: leanness assessed using an ‘ULTRA FOM 100’ apparatus manufactured by the Danish company ‘SFK-Technology’, and classified according to the ‘EUROP’ carcass grading system; hot carcass weight ranging from 75.0 to 80.0 kg, as well as from 80.1 to 85.0 kg within each of the ‘EUROP’ grading classes; and gender – from the point of view of the equal number of boars and gilts within each leanness class, as well as within each range of hot carcass weight. It was stated that along with the increase in the hot carcass weight from 75.0–80.0 kg to 80.1–85.0 kg, there was a statistically significant increase in the gain (disregarding the degree of carcass muscling) of valuable elements from the cutting, i.e. loin, neck, and meat of Classes I, II, and III, with their per-cent content in the carcass remaining unchanged and statistically non-confirmed.

Key words: fatteners, hot carcass weight, leanness, culinary elements, meat intended for processing
