Povzetek


Raziskave o ugodni sestavi in vsebnosti mišične maščobe (IMF) pri svežem mesu in hkrati podkožnega maščobnega tkiva (SCF) pri predelavi v izdelke znotraj pasme povečujejo zanimanje za avtohtone pasme. Cilj raziskave je bil določiti maščobno-kislinsko sestavo IMF v najdaljši hrbtni mišici (LD) in v pripadajoči SCF pri slovenskih avtohtonih krško-poljskih prašičih. Tip maščobe 42 krško-poljskih prašičev je značilno vplival na 29 od 35 tukaj določenih maščobnih kislin. SCF je vsebovala več nasičenih maščobnih kislin (SFA) in večkrat nenasičenih maščobnih kislin (PUFA) in posledično manj enkrat nenasičenih maščobnih kislin (MUFA) kot IMF. Pri ekstremih je imela 6–10 % IMF v LD večji delež SFA in MUFA in manj PUFA kot 2–3 % IMF. Debelejša SCF (57–67 mm) je vsebovala več SFA in manj PUFA kot tanjša (30–40 mm). Spol in starost sta prav tako vplivala na maščobno-kislinsko sestavo. Maščoba kastratov je vsebovala več MUFA in manj PUFA kot pri svinjkah. Z naraščajočo starostjo je vsebnost MUFA naraščala.
