    Meat quality and fatty acid profile of pork and backfat from an indigenous breed and a commercial hybrid of pigs

  • Popis výsledku v původním jazyce

    The aim of this study was to verify the hypothesis that carcass traits, quality and oxidative stability of meat, and fatty acids profile in intramuscular fat (IMF) of M. longissimus lumborum et thoracis (MLLT) and backfat (BF) are different between the observed genotypes of pigs. A total of 64 animals were included in the experiment, 32 pigs of native breed Prestice Black-Pied breed (PBP) and 32 pigs of hybrid combination Large White × Landrace sows × Duroc × Pietrain boars (LWLDP). PBP pigs showed higher values of IMF (P≤0.01) and BF, lower lean meat content and drip loss value (P≤0.001) than the LWLDP hybrid. The value of pH45,24 was higher (P≤0.05) in PBP pigs. The analysis of fatty acid profile in MLLT showed higher content of C8:0 (P≤0.01), C10:0 (P≤0.01), C15:0 (P≤0.01), C22:0 (P≤0.05), C18:1 n-9 (P≤0.01), C18:3 n-6 (P≤0.001), C20:3 n-3 (P≤0.05), C20:4 n-6 (P≤0.01), C22:4 n-6 (P≤0.05), C22:5 n-3 (P≤0.01) and C22:6 n-3 (P≤0.01) in LWLDP than in PBP pigs. The opposite trend was observed in C18:1 n-9 (P≤0.01) and C20:5 n-3 (P≤0.01). Higher content of MUFA as well as the MUFA/SFA ratio were found in PBP breed (P≤0.01). Higher levels of C10:0 (P≤0.01), C12:0 (P≤0.01), C14:0 (P≤0.001), C16:0 (P≤0.001), C14:1 n-5 (P≤0.01), C16:1 n-7 (P≤0.05), C18:1 n-7 (P≤0.001), C20:5 n-3 (P≤0.01) and C22:6 n-3 (P≤0.05) in BF were found in LWLDP pigs, however the content of C24:1 n-9 (P≤0.01), C18:2 n-6 (P≤0.05), C18: n-3 (P≤0.05), C20:4 n-6 (P≤0.01) and C22:5 n-3 (P≤0.01) was higher in PBP pigs. SFA content was higher (P≤0.001) in LWLDP hybrid, but PUFA (P≤0.01), n-6 PUFA (P≤0.05) and mainly n-3 PUFA (P≤0.01) were higher in PBP pigs. In BF, the MUFA/SFA (P≤0.05) and PUFA/SFA (P≤0.001) ratios were higher in PBP pigs; on the contrary the MUFA/PUFA (P≤0.05) ratio was higher in LWLDP pigs.
