The effects of reducing dietary omega (n)-6 to n-3 fatty acid (FA) ratios on body fat mobilization in lactating sows (n = 100) were investigated. Treatments consisted of a control (tallow, low polyunsaturated FA, 8:1 n-6:n-3 ratio), 3 diets with plant oil based ratios (9:1P, 5:1P, and 1:1P), and a 5:1 fish oil diet (5:1F). An epinephrine [1.6 μg kg−1 body weight (BW)] challenge was used to measure adipose tissue lipolytic activity (glycerol, NEFA, and leptin) on d 5 of lactation from a subset of sows (9:1P and 1:1P groups) fitted with jugular catheters. Lactation feed intake was greatest for control and 5:1P-fed sows (8.3 kg d−1), lowest for 1:1P-fed sows (7.4 kg d−1), and intermediate for 9:1P- and 5:1F-fed sows (7.7 kg d−1; P = 0.047). Piglet average daily gain (ADG) and estimated milk output were unaffected by diet (P > 0.10). The 1:1P-fed sows had (P < 0.10) greater backfat thickness, increased circulating leptin, and reduced feed intake, which are correlated (P < 0.10) with increased circulating glycerol and NEFA. Sows fed a plant oil based 1:1 n-6:n-3 FA ratio appeared to be in a state of negative energy balance; however, as no effects were observed on piglet ADG, these sows were able to provide the same level of nutrients to their offspring as the 9:1P fed sows.

SummaryNutritional manipulation of diets for layers can help to naturally modify the nutritional content of eggs. The objective of this study was to increase the concentration of the omega-3 fatty acid, docosahexaenoic acid (DHA), in the egg yolk by feeding a diet rich in omega-3 fatty acids from microalgae compared to one containing fish oil to layers. A total of 480 layers (Babcock B308) aged 28 weeks old were divided into four treatment groups with four replicates per treatment. The layers were fed a control diet, a diet containing 4% crude salmon oil, or microalgae (Schizochytrium spp.) at 1% or 2% in the diet for eight weeks. Feed intake and egg production were recorded daily and egg quality tested every two weeks. There were no significant differences between the control and treatment groups as regards feed intake, egg production, egg weight, egg mass, albumin height, and Haugh unit of the eggs. The egg samples were obtained at the start of the trial, four weeks and eight weeks for the analysis of the fatty acid profile in the eggs. The DHA level in the eggs from layers fed even 1% or 2% algae was higher (P < 0.05) compared to the level from those fed with the control diet and 4% fish oil supplementation. The omega 6:3 ratio in eggs was significantly reduced (P < 0.05) compared to the control diet and the fish oil groups. Feeding 2% microalgae (Schizochytrium spp.) in hen diet resulted in an increase in the DHA level (above 100 mg/egg) and a decrease in the omega 6:3 ratio to the optimal level. The trial demonstrated that DHA concentration in eggs can be enriched through nutritional management of layers by using algae supplementation in order to provide more favourable fatty acids for consumers.

This study was conducted to evaluate the effect of different omega-6: omega-3 fatty acid (FA) ratios in a corn–soybean meal-based diet in growing pigs. A total of 140 [Duroc × (Landrace × Yorkshire)] growing pigs with an average body weight (BW) of 24.75 ± 1.43 kg were used in a 6-week trial. Pigs were allocated randomly into one of four treatments according to sex and BW (seven replications with five pigs per pen). The treatment groups consisted of 4 diets with omega-6:omega-3 FA ratios of 17:1, 15:1, 10:1, and 5:1. In the current study, the energy digestibility, BW, and average daily gain (ADG) increased (p < 0.05) in pigs provided with the 5:1 diet compared to pigs fed the 17:1 diet in the sixth week. The low-density lipoprotein (LDL) concentrations of blood were lower (p < 0.05) in pigs fed the 5:1 diet compared to the 17:1 and 15:1 diet. However, the fecal microflora and fecal gas emissions were unaffected (p > 0.05) by the different omega-6: omega-3 FA ratios in diets. In conclusion, reducing omega-6: omega-3 ratio by increasing omega-3 in diet improved BW, ADG, and gross energy digestibility, and reduced the LDL concentrations of blood in growing pigs.

AbstractLong-Chain Polyunsaturated Fatty Acid (LCPUFA) is essential throughout pregnancy, since deficiency of LPUFA may linked to obstetrical complications. This study aimed to investigate LCPUFA status in severe preeclampsia and preterm birth. A cross sectional study was conducted in 104 pregnant women, which divided into normal pregnancy, severe preeclampsia and preterm birth groups. Serum percentage and concentration of total LCPUFA, omega-3, alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), omega-6, linoleic acid (LA), and arachidonic acid (AA) were measured using gas chromatography/mass spectrometry. Receiver operating characteristic (ROC), bivariate and multivariate analysis were performed. Severe preeclampsia showed the highest concentration of total PUFA and the lowest DHA percentage, with significantly higher Omega-6/Omega-3 ratio (p = 0.004) and lower omega-3 index (p < 0.002) compared to control. Preterm birth showed the least omega-3 concentrations, with significantly low omega-6 derivates (LA (p = 0.014) and AA (p = 0.025)) compared to control. LCPUFA parameters have shown to increase the risk in both conditions, particularly ALA ≤ 53 µmol/L in preeclampsia with OR 5.44, 95%CI 1.16–25.42 and preterm birth with OR 4.68, 95%CI 1.52–14.38. These findings suggest that severe preeclampsia and preterm birth have an imbalance in LCPUFA status.

Context. Several studies have shown a link between proinflammatory activity and the presence or deficit of some fatty acids. Inflammation is associated with several diseases including diabetes.Objective. To characterize and compare the fatty acids profiles in children with inaugural type 1 diabetes, diabetic children (at least 1 year after diagnosis), and healthy children.Design. Plasma fatty acids profiles in children with inaugural diabetes, children with noninaugural diabetes, and controls, all of whom were prepubescent with a BMI < 85th percentile, were evaluated.Results. Omega-3 fatty acid levels were higher in recently diagnosed subjects with diabetes than in controls. The ratio of omega-6/omega-3 fatty acids was higher in the control population. Omega-6 fatty acid levels were higher in the nonrecent diabetic subjects than in the children with recently diagnosed diabetes, and the levels were higher in the nonrecent diabetes group compared to the control group.Conclusion. Our findings showed higher levels of alpha-linolenic acid, EPA, and DHA, as well as mono- and polyunsaturated fatty acids, in diabetic children. These findings reinforce the importance of precocious nutritional attention and intervention in the treatment of diabetic children.

The study to find cocoa butter equivalent (CBE) as an alternative to cocoa butter (CB) from available and low cost commercial oils or fats has been increased recently. Current study investigates the blending of hard palm oil mid-fraction (PMF) with canola oil to produce high nutritional CBE using immobilized lipase from Rhizomucor miehei. The experiments were designed using Response Surface Methodology (RSM) to optimize the percentage of saturated-unsaturated-saturated (StUSt) triacylglycerols (TAGs). The experiment was performed at hard PMF concentration of 50 to 90% (w/w), lipozyme load between 5% and 10% (based on the weight of substrate) with a reaction time between 2 to 14 hours. The best reaction conditions to attain this target was 89.35% (w/w) of hard PMF concentration, 2 hours of reaction time, and 5% (based on the weight of substrate) of lipozyme load, resulting CBE which contains 64.44±1.18% of StUSt. The addition of canola oil improved the nutritional value of CBE which was marked by the higher percentage of linoleic acid (omega-6, 4.53±0.06%) and linolenic acid (omega-3, 0.74±0.14%) in CBE than CB (omega-6, 2.68±0.34%). Enzymatic interesterification was not altering fatty acid content in the CBE, especially linoleic acid (omega-6) and linolenic acid (omega-3) which was characterized by no significant difference (p > 0.05) between the fatty acid profile of initial mixture (before interesterification) and CBE (after interesterification).
