The effect of different fixed factors on pig carcass quality and meat traits

Abstract

Objective of the paper was to investigate the effect of the sire breed (Swedish landrace and Large Yorkshire) and sex (female animals and male castrates) on quality of carcass and pig meat. Established fat thickenss was the highest at withers (33,21 mm) and the thinnest at rump in the center of m. gluteusa medius (18,48 mm). Sire breed had influence (p<0,01) on back fat thickness in the central part, whereas sex influenced (p<0,05) backfat thickenss at withers. Lean meat of Swedish Landrace progeny established by partial dissection EU was 52,91 % and according to current Regulation 42,89 % and it was higher compared to progeny (SLxLY) whose sires were Large Yorkshire breed. Established difference in share of meat between sire breeds by application of these two methods was 10,02 and 8,83 %. Higher share of meat (EU 53,20 %) was established in female progeny by 2,27 % in comparison to male progeny (p<0,05). Also, sire breed influenced (p<0,05 and p<0,01) pH, water binding capacity, softness and thickenss of muscle fibre, whereas the sex influenced (p<0,01) colour of musculus longissimus. Sire breed and sex had no influence on investigated chemical traits of m. longissimus (p>0,05). .
