Contribution to study of evaluation of the quality of pig carcasses according to method recommended by EU with focus on withers fat thickness

Abstract

The quality traits of Swedish landrace pig carcasses were investigated. According to short procedure of the method pf partial dissection described in detail by Walstra and Merkus (1996) the highest relative yield of muscle tissue in leg/ham, shoulder, back-loin section and belly-rib fat in carcasses of pigs with thinner withers fat - I group ( 65,76; 66,32; 50,70 and 53,95%). The highest relative share of intermuscular fat in shoulder, back-loin section and belly-rib fat was established in pigs with thicker withers fat - II group (3,16; 5,63 and 7,96%). Differences were significant at the level of 5%. Higher yield of muscle tissue in carcasses was determined in fatteners with thinner withers fat - I group (57,83%) and differences between I and II research groups weren’t significant (p>0,05).

Ispitivane su osobine kvaliteta svinjskih trupova švedskog landrasa po skraćenom postupku metodom parcijalne disekcije, koju su detaljno opisali Walstra i Merkus (1996). Utvrđen je najveći relativni prinos mišićnog tkiva u butu, plećki, leđno-slabinskom delu i trbušno-rebarnoj slanini u trupovima svinja sa tanjom slaninom na grebenu - I grupa (65,76; 66,32; 50,70 i 53,95%). Najveći relativni udeo intermuskularne masti (3,16; 5,63 i 7,96%) u plećki, leđno-slabinskom delu i trbušno-rebarnoj slanini imale su svinje sa debljom slaninom na grebenu - II grupa. Razlike su bile značajne na nivou 5%. Veći prinos mišićnog tkiva u trupovima utvrđen je kod tovljenika sa tanjom slaninom na grebenu- I grupa (57,83%) a razlike između I i II ispitivane grupe nisu bile signifikantne (p>0,05).
