Total of 40 castrated fatteners of Swedish Landrace breed, divided into two groups based on their gender (20 pigs in each group) were used in the study to determine the effect of gender on share of tissues and chemical composition of the fat taken from the belly carcass part. All pigs were fed diet containing additive of 1.25% of soybean oil. Even though the weight of belly part was similar in animals of both genders, female animals had higher share of muscle tissue (P (lt) 0.05), whereas male animals had higher share of intermuscular and total fat tissue (P (lt) 0.01). Addition of soybean oil, with high share of PUFA, to pig nutrition can significantly influence the increase of unsaturated fats. Female fatteners had more extracted fat in fat tissue and higher content of PUFA, however, statistically significant difference was established only in share of SFA, which was considerably lower (P (lt) 0.05) in comparison to male animals. Consequently, PUFA:SFA ratio was significantly higher ...in female animals (0.51) compared to male fatteners (0.39). Iodine number/value determined for fat was in the range from 63.00 in males to 64.36 in female animals without statistically significant difference. Based on obtained results it can be concluded that, in regard to the nutritional quality, belly part from female fatteners may provide a balanced fatty acid intake for consumers (PUFA:SFA>0.4). However, in regard to the technological quality, fat (bacon) obtained from female animals had lower sustainability, due to more rapid fat oxidation, and it was of poorer technological quality due to softer fat tissue and more difficult cutting.
Ukupno 40 kastriranih tovljenika rase švedski landras, podeljenih u dve grupe u zavisnosti od pola (po 20 svinja u grupi), je iskorišćeno za utvrđivanje uticaja pola na udeo tkiva i hemijski sastav masti trbušno-rebarnog dela. Sve svinje su hranjene sa dodatkom 1,25% sojinog ulja. Pol životinja nije značajno uticao na težinu trbušno-rebarnog dela, međutim, utvrđeno je da su ženska grla imala veći udeo mišićnog tkiva (P (lt) 0,05), dok su muška imala veći udeo intermuskularnog i ukupnog masnog tkiva (P (lt) 0,01). Dodatak sojinog ulja, koje ima visok udeo PUFA, u ishranu svinja, može značajno da utiče na povećanje nezasićenosti masti. Ženski tovljenici su imali više ekstrahovane masti u masnom tkivu i veći sadržaj PUFA, međutim statistički značajna razlika je utvrđena samo u udelu SFA, koji je bio značajno niži (P (lt) 0,05) u odnosu na muška grla. Kao posledica toga, odnos PUFA:SFA je bio značajno veći kod ženskih grla (0,51) u odnosu na muška (0,39). Jodni broj masti se kretao od 63,0...0 kod muških do 64,36 kod ženskih životinja i nije se statistički značajno razlikovao. Na osnovu dobijenih rezultata može se zaključiti da je, u pogledu nutritivnog kvaliteta, trbušno-rebarni deo ženskih tovljenika kvalitetniji u pogledu masno-kiselinskog sastava (PUFA:SFA>0.4). Međutim, u pogledu tehnološkog kvaliteta, slanina dobijena od ženskih životinja bi imala manju održivost, usled brže oksidacije masti, i bila bi lošijeg tehnološkog kvaliteta, zbog mekanog masnog tkiva i otežanog sečenja.
