This study investigated the effects of feeding High-Moisture Corn (HMC) on meat production performance, mutton quality, muscle metabolism, and gut microbiota in Kazakh rams. Thirty-two 6-month-old Kazakh rams were divided into a control group (CT) and an experimental group (GS). Both groups received a basal diet consisting of 30% whole-plant corn silage, 30% cotton residue, and a concentrate mixture. In the CT group, the concentrate contained 24% ordinary crushed corn (on a dry matter basis). In the GS group, half of the ordinary crushed corn was replaced with HMC, resulting in a concentrate containing 12% ordinary crushed corn and 12% HMC. After a 120-day feeding period, backfat thickness was significantly higher in the GS group (p < 0.05); For meat quality, muscle shear force was significantly lower (p < 0.01) and intramuscular fat content was significantly higher (p < 0.01) in the GS group; Amino acid analysis showed that aspartic acid content was significantly lower (p < 0.01), arginine and glutamine contents were significantly lower (p < 0.05), and glycine content was significantly higher (p < 0.05) in the GS group; Fatty acid analysis revealed that the contents of methyl undecanoate, methyl myristate, methyl palmitate, methyl heptadecanoate, methyl alpha-linolenate, and all-cis-4,7,10,13,16-docosapentaenoic acid were significantly higher in the GS group (p < 0.01), while the contents of ten other fatty acids, including methyl caprate, methyl laurate, and methyl tridecanoate, were significantly higher (p < 0.05); A total of 668 metabolites were detected by muscle metabolomics, and 20 of them were identified as significantly differential metabolites, with the GS group showing 15 upregulated and 5 downregulated, mainly enriched in four pathways: valine, leucine and isoleucine biosynthesis; taurine and hypotaurine metabolism; pantothenate and CoA biosynthesis; and the citrate cycle (TCA cycle); Gut microbiota analysis showed no significant difference in alpha diversity, but beta diversity was significantly separated between the two groups (p < 0.01); Correlation analysis revealed that Firmicutes_A was significantly negatively correlated with most fatty acids, while Proteobacteria was significantly positively correlated with multiple fatty acids (p < 0.05). In conclusion, The GS group had significantly increased backfat thickness, reduced muscle shear force, increased intramuscular fat content, and significantly enriched beneficial fatty acids in Kazakh rams, thereby improving meat quality.

A novel urea complexation technology was developed based on the agglomeration phenomenon induced by ambient-temperature agitation of a ternary system consisting of urea, water and fatty acid ethyl esters (EEs). The agglomeration phenomenon can be regarded as an intuitive indicator to judge the occurrence of urea complexation. Using docosahexaenoic acid (DHA) containing EE (DHA-EE) from Crypthecodinium cohnii oil as the substrate, key variables including agglomeration time, urea/DHA-EE ratio, water/DHA-EE ratio, and temperature were investigated. The urea complexation predominantly occurred within 15 min following agglomerate formation. Temperature in the range of 0–40°C exerted no significant effect on the yield of the non-urea-complexed fraction or its DHA content, enabling the operation to be conducted at room temperature without heating or cooling. Under unoptimized conditions, the proposed method effectively increased the DHA content of EE from Crypthecodinium cohnii oil from 40.73% to 89.87%. For EE from Schizochytrium sp. oil, the contents of DHA and docosapentaenoic acid were improved from 47.17% and 13.93% to 69.30% and 20.29%, respectively. Meanwhile, the contents of eicosapentaenoic acid and DHA in two EE form fish oils were enhanced from 18.26% and 11.76% to 34.86% and 22.96%, and from 13.30% and 57.24% to 15.66% and 68.68%, respectively. The present study provided a novel technical pathway for the efficient enrichment of polyunsaturated fatty acids. Full article

Docosahexaenoic acid (DHA) is an essential ω-3 polyunsaturated fatty acid (PUFA) with high nutritional and pharmaceutical value. The marine protist Aurantiochytrium is a promising industrial DHA producer; however, its DHA biosynthesis via the PUFA synthase pathway co-produces ω-6 docosapentaenoic acid (DPA), limiting DHA purity. Here, we introduced an ω-3 desaturase from Phytophthora infestans (Pin-O3D) into Aurantiochytrium sp. SD116. Functional validation in an Escherichia coli system co-expressing the native PUFA synthase confirmed that Pin-O3D converts DPA to DHA, shifting the DHA/DPA ratio from 1:1 to 2:1. Pin-O3D was then integrated into the fatty acid synthase (FAS) locus, simultaneously attenuating FAS activity and enabling heterologous gene expression. The engineered strain ΔFAS-Pin-O3D exhibited significantly (p < 0.0001 in t-test) increased DHA content (55.2% of total fatty acids) and DHA/DPA ratio (5.91) in shake flasks, with no negative impact on biomass or lipid accumulation. Fed-batch fermentation confirmed the scalability of this strategy, achieving a >20% increase in DHA/DPA ratio. This study demonstrates that combining heterologous ω-3 desaturase expression with FAS attenuation is an effective approach for optimizing PUFA profiles in Aurantiochytrium. Full article

Background: n-3 Docosapentaenoic acid (DPA; 22:5 n-3) is increasingly viewed as a distinct long-chain omega-3 fatty acid with biological activities that are not fully captured by eicosapentaenoic acid (EPA) or docosahexaenoic acid (DHA). However, progress remains limited by restricted access to high-purity DPA: most commercial sources contain DPA as a minor component, and published isolation strategies often yield only enriched mixtures or require multi-step workflows that are difficult to scale in standard laboratories. Objectives: We aimed to establish a robust, laboratory-accessible purification workflow to obtain DPA ethyl ester at high purity while preserving oxidative quality. Methods: Candidate lipid sources were screened to select an optimal DPA-containing feedstock. Oils were stabilized with antioxidants and pre-fractionated by cold crystallization (−20 °C) to reduce saturated lipids and oxidation by-products. Preparative separation used a stacked C18 flash system (15 μm + 45 μm in series) operated isocratically (methanol/water 92:8, v/v) at 120 mL/min. Fractions were analyzed by GC and iteratively reinjected to progressively enrich the DPA window. Solvent was recovered by distillation and reused. Results: Omegavie^® 4020EE (5.4% n-3 DPA) was identified as the best starting material. Pretreatment eliminated detectable TBARS-derived malondialdehyde. The isocratic purification-loop strategy produced tens of grams of DPA ethyl ester at >98% purity (GC–FID) defined as n-3 DPA area% of total identified fatty acid methyl esters by GC–FID, with per-cycle DPA recovery of 91–95%, overall recovery of 76% from the starting DPA content, and >90% solvent recycling. The workflow is scalable at the gram-to-tens-of-grams level for research laboratories, although solvent burden and column maintenance remain practical constraints for larger-scale implementation. Identity and purity were confirmed by GC–MS and ^1H NMR, and oxidation indices remained low (peroxide value < 0.2 meq/kg; p-anisidine < 3). Conclusions: This scalable, solvent-conscious protocol enables reliable access to high-purity DPA and should be adaptable to other low-abundance polyunsaturated fatty acids. Full article

Intramuscular fat (IMF) significantly influences meat quality, particularly flavor. The gastrointestinal microbiota can regulate lipid metabolism. The relationship between intramuscular fat metabolism, rumen microbiota, and beef quality remains unclear. This study enrolled 22 30-month-old Xinjiang Brown Beef cattle, which were randomly allocated to two groups: an intact bull group (n = 15) and a castrated bull group (n = 7). All experimental animals were housed and maintained under consistent feeding and management conditions throughout the entire experimental period. By combining in vivo ultrasonography, slaughter trials, rumen microbiome diversity analysis, and metabolomics techniques, and after adjusting for covariates including intramuscular fat (IMF) content, body weight, and backfat thickness, the present study demonstrated that castration regulates muscle lipid metabolism by reshaping the composition of the rumen microbial community, thereby exerting a cascading effect on key beef quality traits. (1) Production and meat quality: Live weight, carcass weight, eye muscle area, backfat thickness, and intramuscular fat (IMF) content were significantly higher in the YN group than in the GN group (p < 0.01). Conversely, dressing percentage, shear force value, and muscle protein content were significantly lower in the YN group than in the GN group (p < 0.01 or p < 0.05). (2) Rumen microbiota–metabolite correlation: Significant differences existed in microbial composition and community structure between groups (with significant differences in both α and β diversity). Core microbes regulated by castration exhibited distinct co-variation patterns with metabolites: genera such as Anaeroplasma showed significant positive correlations with hydroxy fatty acids, while Sharpea and others showed significant negative correlations with saturated fatty acids. (3) Microbial–metabolite axis and host phenotype correlation: Axes composed of Eubacterium uniforme and others showed significant positive correlations with IMF, while Docosapentaenoic acid (22n-3) exhibited significant negative correlations with IMF. Anaeroplasma and others showed significant positive correlations with oleic acid and others, as well as BFT, while saturated fatty acids showed significant negative correlations with BFT. (4) Covariate validation: After adjusting for covariates including body weight, backfat thickness, and IMF, castration was confirmed to significantly regulate the abundance/content of core genera such as Anaeroplasma, Eubacterium uniforme, as well as key metabolites such as hydroxy fatty acids and docosapentaenoic acid (22n-3) (p < 0.05 after adjustment), making it a core driver regulating rumen microbial composition and muscle lipid metabolism. After adjustment, the regulatory effects of IMF, body weight, and backfat thickness on the aforementioned microorganisms and metabolites were no longer significant (adjusted p > 0.05). Intramuscular fat (IMF), body weight, and backfat thickness are not independent drivers but rather indirect effects resulting from castration-induced physiological state remodeling. This study did not include feeding rate measurements, which represents a limitation. Future research should incorporate this data to further validate the conclusions. This study elucidates the interactive mechanisms between rumen microbiota and their metabolites, identifies the key pathways governing intramuscular fat (IMF) deposition, pinpoints potential regulatory targets for beef quality optimization, and clarifies the intermediate regulatory mechanisms underlying the modulation of meat quality traits by castration.

Nitrite is a common toxic substance in aquaculture, and microplastics are environmental pollutants capable of adsorbing small molecules/particles. Shrimp rely mainly on the hepatopancreas to accomplish detoxification metabolism. In this study, we investigated the individual and combined effects of nitrite and microplastics on the physiological function of the P. vannamei hepatopancreas. The results demonstrated that both nitrite and microplastics induced morphological damage, with the combined stress exacerbating tissue damage. Oxidative stress biochemical indicators were disrupted, and most enzyme activities and gene expression levels were upregulated to varying degrees in each experimental group. The expression levels of immune genes (cytC, CASP-3, Crus, ALF, and proPO), detoxification metabolism genes (CYP450, EH1, SULT, and UGT), and oxidative-stress-related genes (ROMO1, SOD, GPx, and Trx) exhibited different fluctuations. Nitrite and microplastic stress resulted in altered hepatopancreatic function, mainly involving amino acid biosynthesis and metabolism, ABC transporters, oxidative phosphorylation, and the mTOR pathway. We identified 17 metabolic biomarkers, including 6 lipids (Oleic acid, Prostaglandin G2, Linoleic acid, Palmitic acid, Docosahexaenoic acid, Docosapentaenoic acid), 6 amino acids (L-Leucine, Agmatine, L-Arginine, L-Tyrosine, Ornithine, N-Acetylornithine), and 5 carbohydrates (Glyceric acid, Citric acid, D-Mannose, Sorbitol, Fumaric acid). These findings suggest that nitrite and microplastic stresses cause hepatopancreatic tissue damage and induce oxidative stress, physiological and metabolic dysfunction in the shrimp P. vannamei, thereby impacting its normal physiological functions.

Echium species, abundant in the Canary Islands, contain unique fatty acids (FA) such as stearidonic acid (SDA; 18:4n-3) and γ-linolenic acid (GLA; 18:3n-6), which may improve egg quality while valorizing local genetic resources. This study evaluated the effects of Echium plantaegineum oil (EO) compared with linseed oil (LO) and soybean oil (SO) on productive performance, egg quality, sensory traits, and yolk fatty acid profile. Forty-eight hens from the Canary Islands were fed for 31 days with diets supplemented with 1.25% SO (SO-d), 1.1% LO + 0.15% beef tallow (LO-d), and 1% EO + 0.25% LO (EO-d). LO supplementation reduced laying rate and egg mass with respect to SO, increasing feed conversion ratio (FCR), whereas EO produced slightly lighter eggs compared to the SO group but with normal yolk proportion and shell traits. EO markedly increased egg yolk deposition of SDA, eicosapentaenoic acid (EPA; 20:5n-3), docosapentaenoic acid (n-3 DPA; 22:5n-3), and docosahexaenoic acid (DHA; 22:6n-3), while lowering the n-6/n-3 ratio and thrombogenic index (TI). No differences were observed in the evaluated sensory attributes among treatments. In conclusion, dietary inclusion of EO effectively enriches eggs with n-3 LC-PUFA without negatively affecting sensory quality, supporting its potential use as a functional ingredient in laying hen diets.

Background: Pathogenesis of aortic stenosis (AS) involves lipid infiltration, inflammation, and oxidative stress, which drive calcification of the aortic valve and progression to heart failure (HF). Fatty acids (FAs) play a crucial role in these processes. A treatment option for severe symptomatic AS in elderly and high-risk patients is transcatheter aortic valve implantation (TAVI). Objective: To investigate the change in FA profiles in patients undergoing TAVI. Methods: This single-center prospective study included 25 patients with severe AS qualified for TAVI procedure. Blood samples were collected before TAVI and after six months. FA profiles were analyzed by gas chromatography-electron ionization mass spectrometry. Results: Notable changes were identified in FA profiles, including a reduction in docosahexaenoic acid (DHA) levels (117 ± 48.0 µM vs. 141 ± 53.0 µM, p = 0.001) and an increase in alpha-linolenic acid (ALA) concentration (32.8 ± 12.3 µM vs. 19.9 ± 6.40 µM, p = 0.003) six months post-TAVI. Additionally, significant elevations were noted in specific medium-chain FAs (C12) and branched-chain fatty acids (iso C16, iso C17 and anteiso C15, anteiso C17) at six months after TAVI. However, total n-3 polyunsaturated fatty acids (n3 PUFA) levels decreased (p = 0.039), while n-6 polyunsaturated fatty acids (n6 PUFA) levels exhibited no significant overall change at this time point. Decrease in mean pressure gradient (PG) was negatively correlated with eicosapentaenoic acid (EPA), DHA, n-3 docosapentaenoic acid (DPA n3) and n3 PUFA levels in a six-month observation. Conclusions: Our results underscore the complex interplay between cardiac intervention and FA changes, providing novel insights into the metabolic impact of TAVI on FAs serum profile. Full article

The nutritional value of lipids depends not only on their fatty acid composition but also on their stereospecific positioning on the glycerol backbone. This study investigated the fatty acid composition and sn-2 positional distribution of triacylglycerols (TAG), as well as the composition of major phospholipids in golden pompano (Trachinotus ovatus) juveniles (initial weight: 10 g) fed five diets including graded levels of dietary n-3 highly unsaturated fatty acids (HUFA; 0.64–2.10%) for 56 days. With increasing dietary n-3 HUFA levels, the proportions of eicosapentaenoic acid (EPA), docosapentaenoic acid (DPA), docosahexaenoic acid (DHA), and total n-3 HUFA in muscle TAG, phosphatidylcholine (PC), and phosphatidylethanolamine (PE) significantly increased. Phospholipids, especially PC and PE, were preferentially enriched with n-3 HUFA, and the sn-2 positions of TAG showed a significantly increased deposition of DHA and reduced n-6/n-3 ratios. RNA-Seq analysis was performed on muscle tissues of T. ovatus subjected to different dietary n-3 HUFA levels to further investigate the molecular mechanisms of lipid compositional and structural changes. A total of 126,792 unigenes were obtained, of which 47.78% were successfully annotated. KEGG pathway enrichment analysis implicated the glycerophospholipid, glycerolipid, and sphingolipid metabolism pathways in lipid composition and distribution regulation, identifying gpat4, agpat3, agpat8, lpeat1, and lpgat1 as potential regulators. These findings offer insights into lipid remodeling in marine fish and support strategies to enhance aquaculture product quality. Full article

Background and Objectives: We have previously reported that omega-3 polyunsaturated fatty acids (PUFAs) derived from fish oil (FO) is an effective treatment for type 1 and type 2 diabetes neural and vascular complications. As omega-3 PUFAs become more widely used as a nutritional and disease modifying supplement an important question to be addressed is what is the preferred source of omega-3 PUFAs? Methods: Using a type 2 diabetic rat model and early and late intervention protocols we examined the effect of dietary treatment with omega-3 PUFAs derived from menhaden (fish) oil (MO), krill oil (KO), algal oils consisting primarily of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) or combination of EPA + DHA, or pharmaceutical-derived ethyl esters of EPA, DHA or combination of EPA + DHA. Nerve related endpoints included motor and sensory nerve conduction velocity, heat sensitivity of the hind paw, intraepidermal nerve density, cornea nerve fiber length, and cornea sensitivity. Vascular reactivity to acetylcholine and calcitonin gene-related peptide by epineurial arterioles that provide blood to the sciatic nerve was also examined. Results: The dose of each omega-3 PUFA supplement increased the content of EPA, docosapentaenoic acid (DPA), and/or DHA in red blood cell membranes, serum and liver. Diabetes caused a significant decrease of 30–50% of neural function and fiber occupancy of the skin and cornea and vascular reactivity. Treatment with MO, KO or the combination of EPA + DHA provided through algal oil or ethyl esters provided significant improvement of each neural endpoint and vascular function. Algal oil or ethyl ester of EPA alone was the least effective with algal oil or ethyl ester of DHA alone providing benefit that approached combination therapies for some endpoints. Conclusions: We confirm that omega-3 PUFAs are an effective treatment for DPN and sources other than fish oil are similarly effective. Full article

Sea urchins (Echinoidea) are marine echinoderms commonly consumed as seafood in East Asia. To date, various metabolic components of sea urchins have been analyzed, and their health benefits for humans have also been attracting attention. Lipids are the major biomolecules present in sea urchins. However, the comprehensive lipid profiling of sea urchins is limited. In this study, we aimed to perform the comprehensive lipid profiling of six types of sea urchins using liquid chromatography–mass spectrometry (LC/MS). The application of untargeted lipidomics led to the identification of 281 lipid molecular species in six varieties of fresh sea urchin gonads. Each lipid metabolite was identified based on its retention time and MS/MS fragmentation pattern. The results of the analysis showed the highest abundance of lipid percentage in Kitamurasakiuni (14.3%), followed by Hokuyobafununi (12.4%). In all the analyzed sea urchins, glycerolipids such as triacylglycerols were found to be the most abundant lipid components. Multivariate analysis revealed that Murasakiuni showed a different lipid profile from the other types. Interestingly, the polyunsaturated fatty acid to saturated fatty acid ratios and health-related nutritional indices factors were found to be higher in Hokuyobafununi compared to other varieties. The ω-3 fatty acids, such as docosapentaenoic acid (FA 22:6) and eicosapentaenoic acid (FA 20:5), were also abundant in Hokuyobafununi. Lipids such as ether and N-acyl-type lysophosphatidylethanolamines were detected for the first time in sea urchins. This study highlights the nutritional significance of sea urchins and their potential use in the development of functional foods. Full article

This study evaluated the effect of two levels of extruded linseed (EL) in the diet on growth performance, carcass yield, and meat quality of growing rabbits. Sixty-nine New Zealand White male rabbits (Oryctolagus cuniculus) were assigned after weaning to three dietary groups: control (C), 2.5% EL (L2.5%), and 5% EL (L5%). At the end of the fattening period (from 37 to 93 days of age), rabbits were slaughtered. EL supplementation significantly reduced average daily weight gain (ADG) in the L5% group (p < 0.05), while other performance parameters were not significantly affected. Meat from the L5% group exhibited a higher fat content (p < 0.001) and lower water-holding capacity (p < 0.05) compared to the others. The fatty acid profile showed a significant increase in n-3 polyunsaturated fatty acids (PUFAs) and a decrease in n-6 PUFA (p < 0.05), resulting in a markedly reduced n-6/n-3 ratio (p < 0.001) in supplemented groups. EL supplementation also enhanced long-chain n-3 PUFA levels, particularly docosapentaenoic acid (DPA). Although lipid oxidation was slightly increased (p < 0.05), sensory attributes remained unaffected. These findings support EL supplementation as a nutritional strategy to increase the n-3 fatty acids in rabbit meat without compromising physical and sensory quality. Full article

Interest in indigenous and dual-purpose chicken breeds for sustainable poultry farming is growing. Additionally, incorporating local feed resources into their diets may enhance the nutritional value of their products while reducing environmental impact. This study investigated the ability of Echium oil (EO), rich in stearidonic acid (SDA, 18:4n-3) compared to linseed oil (LO) and high in alpha-linolenic acid (ALA, 18:3n-3), to increase long-chain n-3 polyunsaturated fatty acids (LC-PUFAs) in breast meat. Sixty Canarian cockerels were fed for six weeks with diets supplemented with 1.5% soybean oil (SO), 1.5% LO, or 2% EO. Final body weight and carcass traits showed no significant differences among groups (p > 0.05). However, EO-fed birds exhibited slightly higher breast meat lightness (L*) than LO-fed ones (p < 0.05). Total lipid content and lipid class composition remained unchanged (p > 0.05). Both LO and EO increased eicosapentaenoic acid (EPA, 20:5n-3) compared to SO, with EO further enhancing SDA, 20:3n-3, 20:4n-3, docosapentaenoic acid (DPA, 22:5n-3), and docosahexaenoic acid (DHA, 22:6n-3), resulting in meat with a healthier thrombogenic index (TI). Importantly, EO inclusion up to 2% did not negatively impact meat sensory qualities. These findings suggest that EO outperforms LO in enriching poultry meat with beneficial n-3 LC-PUFAs and holds great potential for poultry production. Full article

Sustainably farmed Atlantic salmon could drive global food system solutions by contributing essential nutrients to the human diet while delivering high-quality protein. One of the biggest obstacles to sustainable salmon aquaculture in Chile is the prevalence of piscirickettsiosis disease caused by the Gram-negative bacteria Piscirickettsia salmonis and the excessive amount of antibiotics used to eradicate this disease. Farmed salmon products can be consumed without prior processing and therefore present a substantial risk for the transfer of resistant pathogens to humans. Antibiotics also carry the risk of antibiotic residues and damage to the environment. An alternative to antibiotics is the use of natural antimicrobials without the negative influence on the consumer’s microbiome. Here, we evaluate the potential antimicrobial activity against P. salmonis of the marine microalgae Microchloropsis gaditana. A non-genetically modified M. gaditana was grown with nitrogen deprivation to improve the synthesis of the eicosapentaenoic fatty acid (EPA). A spray-dried M. gaditana concentrate (Mg) was elaborated and given to Atlantic salmon for a period of 49 days, and serum and fillet samples were collected. Our results showed a significant increase in the nutritional quality improving the levels of EPA+ Docosapentaenoic acid (DPA) (23%) and Vitamin D₃ (106%) of the fillets treated with Mg. Fish fed serum were challenged with P. salmonis, and serum antibacterial activity was measured. Sera from fish fed Mg-enriched diets showed a significant increase in antibacterial activity (85.68%) against P. salmonis. Our results indicate that Mg can be used as a viable alternative to address the critical problem of microbial resistance and to assure consumers that farm-raised Atlantic salmon is safe.

Background/Objectives: This study investigated the effects of maternal metabolic syndrome during pregnancy on hepatic fatty acid metabolism and betacellulin expression in rat offspring. A rat model of maternal metabolic syndrome was created with a high-fructose diet (15% fructose in drinking water for six months). Methods: The females with metabolic syndrome were divided into the CON group, the HF group, which received fructose in drinking water, and the HF-DHA group, which received fructose in water and increased amounts of DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) in the diet (2.5% fish oil in the diet). The male and female offspring were killed at birth and their liver tissue was analyzed for the fatty acid profile and expression of Δ-9-desaturase and betacellulin. Results: When the rat offspring were exposed in utero to maternal fatty acids altered by the high-fructose diet, this resulted in a similarly altered fatty acid profile in the liver, with the most significant changes being Δ-9 desaturation and a dramatic increase in monounsaturated fatty acids. The offspring also showed an overexpression of hepatic betacellulin. Supplementation with DHA and EPA increased the DHA content and normalized the fatty acid composition of oleic acid, saturated fatty acids, linoleic acid and n3-docosapentaenoic acid in the offspring of mothers on a high-fructose diet. In addition, the DHA/EPA supplementation of fructose-fed mothers normalized hepatic Δ-9-desaturase and betacellulin overexpression in the offspring, suggesting that DHA/EPA supplementation affects not only the fatty acid content but also the liver function. Conclusions: The changes observed in this study suggest that DHA/EPA supplementation may modulate the effects of maternal programming on disorders of the lipid metabolism in the offspring.
