“…The dietary recommendations for humans discourage the consumption of meat with high concentrations of saturated FA (SFA) in favor of meat with more PUFA or mono-saturated FA. It is known that lipid metabolism in nonruminants, and thus also the carcass lipid quality, could be somewhat managed depending on the composition of the FA that are supplied through the diet as well as by de novo lipogenesis and environmental stressors (White, Richert, & Latour, 2013). However, as more unsaturated fats are supplied with food, and as the degree of unsaturation increases, the more does the consistency of the fat tissue change, gradually becoming soft (Cameron et al, 2000), which affects the technological properties of the meat.…”

The effects of an oregano and/or rosemary (Origanum vulgare L. and/or Rosmarinus officinalis L.) dietary supplementation to the diet of fattening pigs were investigated. Thirty-two grower-finisher pigs (45 kg) were divided into four dietary groups identified as: control diet (CTR); CTR+ 0.2% oregano (O); CTR + 0.2% rosemary(R), and CTR+ 0.1% oregano + 0.1% rosemary (OR). During the finishing period, all groups received a further supplementation of 0.5% of conjugated linoleic acids (CLA). Blood samples were collected after an adaptation period of 15 days to the new diet (T1) and at the end of the finishing period (T2) to evaluate antioxidant status (total antioxidant power and reactive oxygen metabolites) and immune responses (lymphocytic phenotyping and IgG levels). Pork meat samples were evaluated for glutathione peroxidase activity (GSHPx), total phenolic content and preference rating. A significant increase in B lymphocytes (CD79 + ) and a higher IgG level was observed in the R and O groups (P<0.05). Furthermore, there were significant effects of dietary supplementation on meat GSHPx activity and total phenolic contents (P<0.001 and P<0.005, respectively). Preference rating showed that pork derived from group R was the most preferred by the consumers.

“…Most consumers associ-ate the outdoor reareing of pigs with better taste and nutritional value of meat (Nilzén et al, 2001), although a few studies have reported deterioration in sensorial qualities (Enfält et al, 1997). The undesirable effects of outdoor and organic production on the back-fat thickness are evident, and highly depend on environmental conditions and dietary intake (Enfält et al, 1997;Andresen et al, 2001;Gustafson and Stern, 2003;Strudsholm and Hermansen, 2005;Lebret, 2008;White et al, 2013;Martino et al, 2014;Martínez-Miró et al, 2016).…”

Serum lipids as an indicator for the alteration of liver function in patients with hepatitis B

BackgroundHepatitis B virus (HBV) exerts an intense impact on host lipid metabolism. Hence the aim of present study is to determine metabolic derangement that occurred in subjects suffering from hepatitis B patients.MethodsThe fasting blood samples were collected from hepatitis B patients (n = 50) attended in Taluka hospital TandoAdam, Sindh with age and gender matched controls (n = 50). Serum lipid profile and fatty acid (FA) composition were analyzed by micro-lab and gas chromatography.ResultsThe hepatitis B patients have significantly lower level (p < 0.01) of lipid profile including total cholesterol (TC), triacylglyceride (TAG), high density lipoprotein-C (HDL-C) very low density lipoprotein-cholesterol (VLDL-C), low density lipoprotein-cholesterol (LDL-C), and total lipid (TL) in comparison to controls, indicating hypolipidemia in patients. The result of total FA composition of HBV patients in comparison to controls reveal that myristic, palmitic, docosahexaenoic acids were significantly (p < 0.05) higher, while linoleic, eicosatrienoic, arachidonic, eicosapentaenoic acids were lower in HBV patients in comparison to controls. The elongase, ∆5 and ∆6-desaturase enzymes activities were found lower, while ∆9-desaturase activity was higher in hepatitis B patients as compared to controls, which indicates the impaired lipid metabolism.ConclusionThe serum saturated fatty acid (SFA) and monounsaturated fatty acid (MUFA) were increased while polyunsaturated fatty acid (PUFA) was reduced in both total and free form in hepatitis B patients due to altered activities of enzyme desaturases with impaired PUFA metabolism and non-enzymatic oxidation.Electronic supplementary materialThe online version of this article (10.1186/s12944-018-0683-y) contains supplementary material, which is available to authorized users.
