This study aims to evaluate an effect of pig diet supplementation with ethyl esters derived from linseed oil with a high content of alpha-linolenic acid (ALA) on the fatty acids profile of meat. The study was conducted on Polish Landrace fatteners supplemented for a period of 7 weeks (control and experimental groups of 8 animals each, 16 in total). After this period, loin (Longissimus dorsi) and ham (Biceps femoris) samples were collected for laboratory analysis, including basic composition (fat, protein, ash, dry matter) and fatty acids (FAs) profile. The supplementation caused a significant increase in the level of ALA acid, decrease in the content of saturated fatty acids (SFAs), increase in unsaturated FAs level, and resulting decrease in the ratio of n-6/n-3. The indices of atherogenicity and thrombogenicity were beneficially altered in the experimental groups. It can thus be supposed that meat enriched this way may be considered as an interesting choice for consumers who are aware of the importance of diet consumed.

Fatty acids from the omega-3 family are an important element of both human and animal diets. Their activity involves a range of functions for the functioning of a whole organism, and their presence in animal diets can be considered as a means for animal origin product enrichment for human benefit or as compounds profitable for an animal's health status. The aim of this preliminary study was to compare the effect of supplements rich in omega-3 fatty acids (linseed oil, linseed oil ethyl esters, a...

Abstract Recent years have had an increased demand for goat milk and its products. The quality of goat milk is determined, in part, by the fatty acid (FA) profile, but there is little information about breed influence on the FA profile of goat milk. The aim of this study was to describe and compare FA profiles of goat milk produced by Saanen and Swedish Landrace breeds. FA profiles were analysed by gas chromatography with a flame ionisation detector using 100 m capillary column coated with ionic...

Alpha-linolenic acid (ALA) is a polyunsaturated fatty acid (PUFA) comprising of 18 carbon atoms and three double bonds. Because the first double bond counted from the methyl terminus, is at position three, ALA belongs to the so-called n-3 group. Derived mainly from natural plants such as Linum usitatissimum and Perilla frutescens, it is an essential fatty acid for the human body. ALA is essential for the regulation of blood lipid, blood pressure and blood sugar, for the prevention of diseases an...

Abstract Phytosterols (plant sterols) occur in the cells of all plants. They are important structural components that stabilize the biological membranes of plants. Sterols can occur in the “free” unbound form or they can be covalently bound via an ester or glycosidic bond. Since our previous 2002 review on phytosterols and phytosterol conjugates, phytosterol glucosides have been found to be important structural components in the lipid rafts of the plasma membrane of plant cells, where they are t...

Background Over 200 clinical trials have examined the effect of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) supplements on risk factors associated with cardiovascular disease. However, an updated analysis of the evidence is lacking. The aim of the present meta-analysis was to quantify the effect of supplements containing EPA and DHA on risk factors for cardiovascular disease. Methods An analysis was carried on 171 clinical trials with acceptable quality (Jadad score ≥3) that were ...

Abstract Background Omega-3 fatty acids [eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)] are widely recommended for health promotion. Over the last decade, prescription omega-3 fatty acid products (RxOME3FAs) have been approved for medical indications. Nonetheless, there is no comprehensive analysis of safety and tolerability of RxOME3FAs so far. Methods A systematic review of randomized controlled trials (RCTs) was carried out based on searches in six electronic databases. The studi...

Consumers are becoming increasingly interested in food containing appropriately high concentration of intramuscular fat (IMF) and polyunsaturated fatty acids (PUFA). The supplementation of feed with antioxidants decreases degradation of lipids in muscles thereby enhances nutritional and sensory properties of meat. Two experiments were conducted to determine the effects of adding oregano essential oil (OEO) and benzoic acid (BA) to low-protein, amino acid-supplemented diets on meat quality, senso...

ABSTRACTThe effect of dietary fats differing in fatty acid (FA) composition on the metabolism of saturated FA (SFA) and monounsaturated FA (MUFA) in growing pigs was investigated. The deposition of FA in the body and the fate of individual dietary FA were assessed after slaughter. Gilts with an initial body weight (BW) of 60 kg were used as experimental animals. Six pigs were slaughtered at 60 kg BW, while further 18 pigs received three isoenergetic and isonitrogen experimental diets containing ...

This study was conducted to evaluate the effects of protected omega-3 fatty acid and vitamin E on the growth performance, nutrient digestibility, blood profiles and meat quality of finishing pigs. A total of 140 female and castrated-male finishing pigs [(Yorkshire × Landrace) × Duroc] with an average initial bodyweight of 46.5 kg were blocked and stratified based on sex and bodyweight to a 2 × 2 factorial design with the respective factors being (1) without and with 300 IU vitamin E (Vit E), and...
