Content of nutrients and fatty acid composition in meat and pork-butcher’s meat from organic pig production

Przeanalizowano zawartość składników odżywczych i profil kwasów tłuszczowych w mięsie tuczników utrzymywanych i żywionych w warunkach produkcji konwencjonalnej i ekologicznej oraz w wybranych wyrobach wędliniarskich z mięsa tuczników ekologicznych. W mięsie pozyskanym od tuczników ekologicznych stwierdzono nieco większą zawartość składników odżywczych niż od zwierząt trzymanych w warunkach konwencjonalnych. Udział w mieszankach ekologicznych pełnotłustych nasion lnu (5%) przyczynił się do zwiększonego udziału kwasu linolenowego (18:3, n3) w lipidach mięśnia longissimus i adductor w porównaniu do zwierząt żywionych paszami konwencjonalnymi z dodatkiem 2% oleju sojowego. Spośród analizowanych wyrobów wędliniarskich: polędwica, ogonówka, kiełbasa myśliwska, boczek i kabanosy, najbardziej korzystnym profilem kwasów tłuszczowych w żywieniu ludzi cechował się boczek wędzony.There were analyzed nutrient contents and fatty acid profile in meat from fatteners managed and fed under the conventional and organic production conditions as well as in chosen pork-butcher’s meat products from organic fatteners. The meat obtained from organic fatteners showed a slightly higher nutrient contents compared to those managed at the conventional production system. A percentage of full fat flax seeds (5%)in organic diets contributed to an increased linolenic acid level (18:3,n3) in lipids of the longissimus and adductor muscles as against the animals fed conventional diets supplemented with 2% soya bean oil. Among the pork-butcher’s meat products under study, i.e. loin, back bacon sausage, pork hunter sausage, smoked bacon and kabanos dry pork sausage, smoked bacon was proven to have the most favorable nutritional fatty acid composition for human consumption

Effect of inulin extracts or inulin-containing plant supplement on blood lipid indices and fatty acid profile in fattener tissues

The objective of the study was to evaluate the effect of inulin or dandelion, chicory and Jerusalem artichoke powder on lipid indices and fatty acid profile in fattener tissues. The experiment involved 120 crossbred pigs (PL × PLW) × Duroc with an initial body weight of 25.0 ± 0.5 kg. Animals were assigned into 6 groups. A diet for group I (control) did not comprise an inulin additive, group II and III received 2% inulin (water or water-alcohol extraction of inulin from chicory root, respectively), while the mixtures for group IV, V and VI contained 4% root powder from Jerusalem artichoke (topinambur), chicory or dandelion, respectively. The animals were slaughtered at 115 kg body weight. The samples of blood, liver and the muscle longissimus dorsi tissues as well as whole hearts were collected for analysis. Fatty acid profile, some lipid indices and crude fat and cholesterol content were evaluated. Dietary supplement of 40 g dandelion powder resulted in preferable significant changes in the blood lipid indices and fatty acids composition (increased PUFA share and decreased n-6/n-3 ratio)
