Quality of pig carcass and meat of different genotypes

Abstract

Objective of this paper was to present results of investigation of different genotypes on quality of pig carcass and meat. Dissection of four main carcass parts was performed (n=67) in order to present share of tissue in main carcass parts. The quality of pig carcasses was investigated on three genotypes: Swedish Landrace (ŠL/SL) and two hybrid combinations with Durroc and Pietrain (VJ/LW x ŠL/SL) x D and (VJ/LW x ŠL/SL) x P. Meat yield of pig carcass sides was determined by partial dissection and for Swedish Landrace it was 51,30%, and for three breed combination with Durroc 56,04% and for three breed combination with pietrain 58,55%. It was established that genotype of pigs in fattening influenced the quality of meat, since the three breed combination with Pietrain (genotype C) had the lowest share of free fat, the poorest colour and the lowest WBA, and hihger share of ashes compared to results obtained for other genotypes (1,22; 0,27; 46,50 and 1,17).

Cilj rada je bio da se prikažu rezultati ispitivanja uticaja različitih genotipova na kvalitet trupa i mesa svinja. Vršena je disekcija četiri glavna dela trupa, (n=67) da bi prikazali udeo tkiva u osnovnim delovima polutki. Tako je ispitivan kvalitet svinjskih trupova tri genotipa i to: jedna čista rasa, švedski landras (ŠL) i dve hibridne kombinacije sa durokom i pietrenom (VJ x ŠL) x D i (VJ x ŠL) x P. Mesnatost svinjskih polutki utvrđena parcijalnom disekcijom za švedski landras je iznosila 51,30%, trorasnu kombinaciju sa durokom 56,04% i trorasnu kombinaciju sa pietrenom 58,55%. Isto tako, ustanovljeno je da genotip svinja ima uticaj i na kvalitet mesa, jer je trohibridna kombinacija sa pietrenom (genotip C) imala najmanji udeo slobodne masti, najslabije izraženu boju kao i najmanju SVV, a veći udeo pepela u poređenju sa rezultatima ostalih ispitivanih genotipova (1,22; 0,27; 46,50 i 1,17).
