This study evaluated the effect of linseed incorporation in laying hens’ feed (alone or along with a tomato-red pepper mix) on laying hens’ egg yolk fatty acids profile, as well as on their atherogenic (IA) and thrombogenic (IT) health lipid indexes, and the ratio between the hypocholesterolemic and hypercholesterolemic fatty acids (HH). Sixty 27 weeks-old Novogen White laying hens were divided into three groups and given 100 g/hen/day of a standard diet (Control, C) containing 4.5% of ground linseed (Linseed diet, L), containing 1% of dried tomato paste and 1% sweet red pepper (Lineseeds-Tomato-Pepper, LTP). The linseed dietary inclusion significantly reduced the egg yolk content of palmitic acid from 25.41% (C) to 23.43% (L) and that of stearic acid from 14.75% (C) to 12.52% (L). Feeding 4.5% ground linseed did not affect the egg yolk content of α-Linolenic acid but significantly increased the egg yolk concentration of eicosapentaenoic acid (EPA) from 0.011% (C) to 0.047% (L) and that of docosahexaenoic acid (DHA) from 1.94% (C) to 2.73% (L). The IA and the HH were not affected (p > 0.05) by the dietary addition of linseed, whereas the IT decreased (p < 0.05) from 1.16 (C) to 0.86 (L). Adding tomato-sweet red pepper mix to the linseed-supplemented feed did not affect the measured parameters as compared to the linseed dietary treatment.

This study evaluated the effect of dietary incorporation of linseed alone or along with dried tomato paste-pepper powder mix on egg physical characteristics, antioxidant profiles, lipid oxidative status, and yolk coloration before and after storage at 4 °C for one month. Sixty Novogen White laying hens, 27 weeks-old, were divided into three groups and given 100 g/hen/day of a standard diet (C), standard diet containing 4.5% of ground linseed (L), linseed diet containing 1% of dried tomato paste and 1% of sweet red pepper (LTP). Linseeds increased (p < 0.05) egg yolk antioxidant capacity but not lipid oxidative stability (p > 0.05). However, dietary inclusion of LTP did not improve fresh egg yolk antioxidant activity and lipid oxidation stability (p > 0.05). With reference to the stored eggs, only antioxidant activity measured by phosphomolybdenum reduction and lipid oxidative stability were influenced (p < 0.05) by the dietary treatment. Fresh egg yolk of hens fed on linseeds tended to have a slightly more yellow, redder, and less light color than the eggs of hens fed with the control diet. Dietary supplementation of LTP increased (p < 0.05) the Roche yolk color fan (RYCF) score and redness (a*) and decreased (p < 0.05) lightness (L*) without affecting (p > 0.05) saturation (C*). Storage of hens’ eggs fed on the control diet did not influence (p > 0.05) yolk color.

AbstractThe current study was conducted to evaluate egg quality, egg yolk fatty acids, health-related indices and antioxidants from laying hens' eggs fed different combined vegetable by-products, rich in fatty acids and antioxidants. One hundred twenty 50 weeks-old Tetra SL laying hens were divided into three groups. They were given daily a standard diet (Control, C), a diet containing 9% rapeseed meal with 3% grapeseed meal (T1 diet), or a diet containing 9% flaxseed meal and 3% sea buckthorn meal (T2 diet). Hen production performances, egg quality, egg yolk fatty acids total polyphenols content and antioxidant capacity were determined. The T1 diet significantly reduced the egg yolk content of palmitic acid from 76.615 mg (C) to 46.843 mg (T1) and that of oleic acid from 788.13 mg (C) to 682.83 mg (T1). Feeding flaxseed and sea buckthorn meals significantly increased the egg yolk content of α-linolenic acid in T2 yolks (35.297 mg) compared with C yolks (4.752 mg) and that of docosahexaenoic acid (DHA) from 16.282 mg (C) to 74.918 mg (T2). The atherogenicity indices (AI) were not significantly affected, whereas the thrombogenicity indices (TI) decreased significantly (p < 0.0007) from 0.72 (C) to 0.60 (T1) and 0.66 (T2), respectively. Adding this combination of meals to the hens' diets, increased the total polyphenol content and antioxidant capacity in T1 and T2 eggs compared to C eggs. The significant enrichment of eggs with n-3 fatty acids and antioxidant capacity, as well on the health-related indices especially from T2 eggs, represents a potential functional feed ingredient in poultry feeding, to obtain eggs as functional food.

This study was carried out to evaluate the effects of increasing metabolizable energy and soybean oil levels on the egg chemical composition, total lipids and cholesterol contents and fatty acids profile in the egg yolk. Three hundred and sixty 29 week-old Bovans Goldline semi-heavy commercial layers were used during three periods of 28 days. A completely randomized design were used in a 3 × 3 double factorial arrangement with three soybean oil levels (1, 2 and 3%) and three metabolizable energy levels in the diet (2,600, 2,750 and 2,900 kcal/kg), totalizing nine diets with five replicates of eight birds. No interaction soybean oil × metabolizable energy levels was observed. The metabolizable energy levels did not affect any of the determined characteristics. The moisture, ash and protein contents in the egg yolk and albumen and the lipid and cholesterol contents in the yolk were not affected by the soybean oil levels in the diet, while linoleic acid (C18:3) and linolenic acid (C18:2) levels responded linearly. The use of 2,600 kcal ME/kg and 3% of soybean oil in the diet of laying hens with consumption of 120 g/bird/day is justifiable, since this feeding strategy improves the fatty acids profile of the egg.

The present study was designed to evaluate the influence of hemp seed (HS) supplementation on egg yolk cholesterol and fatty acid composition in laying hens. Sixty hens (Rhode Island Red x Fyoumi) were evenly distributed into four groups (three replicates per group) at the peak production (34 weeks). HS was included into the ration at the level of 0.0 (HS-0), 15 (HS-15), 20 (HS-20), and 25% (HS-25) and continued the supplementation for consecutively three weeks. At the end of the experiment, three eggs per replicate were randomly collected and analyzed for egg yolk fatty acids and cholesterol profile. The statistical analysis of the result revealed that supplementation of HS-25 significantly(P<0.05)decreased egg yolk total cholesterol, myristic (C14:0), palmitic (C16:0), and stearic (C18:0). Similarly, total as well as individual monounsaturated fatty acids decreased significantly(P<0.05)while total and individual polyunsaturated fatty acids increased significantly in the HS-25. In addition, total omega-3 and omega-6 increased significantly in the HS-25 group. From the present result, we concluded that addition of HS at the rate of 25% to the diet of laying hens augmented the cholesterol and fatty acids profile in egg yolk.

The aim of this study was to evaluate the effects of different dietary inclusion of raw white lupine seed meal (WL) in diets of laying hen on fatty acids (FA) profile, health lipid indices and oxidative stability of egg yolk. A total of 160 TETRA-SL LL laying hens (30-week old) were used in a ten week trial. The laying hens were randomly assigned to four dietary treatments: control diet which contained soybean meal (C), and study diets in which soybean meal was replaced with WL at 150 g/kg (E15), 200 g/kg (E20) and 250 g/kg (E25). Each treatment was replicated 5 times with 8 birds each. The inclusion of WL in experimental diets caused a linear increase in n-6 and n-3 polyunsaturated FA (PUFA) content and a decrease in monounsaturated FA (MUFA), but it had no influence on the saturated FA (SFA) of egg yolk lipids. The data suggested that the partial replacement of soybean meal with WL of in laying hen diet it significant increase h/H (hypocholesterolemic/Hypercholesterolemic) and PUFA/SFA ratio, and decrease thrombogenic index (TI), which improves human health because of the beneficial effect on the cardiovascular system. The authors determined the concentration of a-tocopherol by high performance liquid chromatography (HPLC) and assessed the degree of oxidative degradation of lipids using the classical test based on the concentration of malondialdehyde (MDA). Inclusion of WL in diets led to increases in a-tocopherol and decrease in MDA in eggs (P [0.05). Egg storage for 20 d or 40 d led to linear reduction in egg �-tocopherol and increase of MDA content (P [0.05). The results of the present study suggest that the seeds of modern white lupine varieties can be included at 250 g/kg in layer diets as an effective substitute for soybean meal, improving fatty acids profile, health lipid indices and oxidative stability of egg yolk.

Abstract Enrichment of docosahexaenoic-acid (DHA) into eggs of laying-hens may be limited by the availability phospholipids as a deposition sink. The present study was to determine if dietary supplementations of phospholipid-component molecules or synthesis-enhancers: choline, serine, and ethanolamine could elevate phospholipid and DHA enrichment in the eggs and tissues of hens. A total of 50-White-Leghorn-Shavers (42-wk old) were individually caged and divided into 5 groups (n = 10/group). The 5 groups of hens were fed the following diets for 3 wk: Diet-1 = a corn soybean-meal basal-diet, Diet-2 = Diet-1 + 4%-microalgae (Aurantiochytrium, Heliae, Gibert, AZ, 1.81 g-DHA/kg) + choline-chloride (26.3 g/kg diet, 60% purity, DSM-Co., Basel, Switzerland), Diet-3 = Diet-2 + 1.41% of L-serine (100% purity, Ajinomoto-Co., Inc., Kawasaki, Japan), Diet-4 = Diet-2 + 100 mg of ethanolamine/kg (99% purity, Sigma-Aldirch-Co., St Loius, MO), and Diet-5 = Diet-3 + 100 mg of ethanolamine/kg. At the end of study, eggs, liver, ovary, and adipose samples were collected from 6 hens/group for biochemical analysis. Data were analyzed by one-way ANOVA. Compared with Diet-1, Diet-2 enhanced (P &lt; 0.05) DHA concentrations in egg yolk and liver by 213 mg/egg and 2.98 mg/g tissue, respectively, but decreased (P &lt; 0.05) total phospholipid-concentrations of yolk and liver by 50%, and hepatic-mRNA levels of elongases-2/5 and desaturases-4/6 by 25–50%. Compared with Diet-2, Diet-5 enhanced (P &lt; 0.05) DHA (by 20%) and phospholipid (by 40%) concentrations in the egg yolk, and upregulated (P &lt; 0.05) lipid-metabolism genes involved in the citicoline (CDP, up-to-3-fold) and CDP-ethanolamine (up-to-2.5-fold) pathways in the liver and ovary-tissue. In comparison, Diets-3 and 4 resulted in only 3–11% higher (P &lt; 0.05) DHA-concentrations in the liver over Diet-2. In conclusion, feeding hens a high DHA and choline diet enriched DHA in the egg yolk and down-regulated lipogenesis-gene-expression in the tissues. Supplementing the diet with extra-serine and ethanolamine further-enhanced the DHA enrichment in the egg yolk and restored the high DHA-mediated changes in the gene-expression.

Abstract Polyunsaturated fatty acids supplementation in late gestation change offspring metabolism; however, their effect is not well known on early gestation in ewes. The objectives of this study were to determine the effect of dietary supplementation with eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in pregnant ewes on the concentration of EPA and DHA on fetal liver (FL) and fetal central nervous system (FCNS), and to evaluate the effect of the supplementation with EPA+ DHA on mRNA expression of genes associated with transport and metabolism of fatty acids (FA) in FL and placenta (caruncles and cotyledons). Twelve ewes (4 pens, three per pen) were blocked by pregnancy day. The ewes were assigned during the first 45 d of gestation to diet with an addition of 1.5% (dry matter bases) monounsaturated FA (MUFA) or EPA+DHA. A C-section was conducted at d 45 of gestation to collect FL, FCNS, caruncle and cotyledon. Data were analyzed using a mixed procedure (SAS). For the placenta mRNA concentration, a 2x2 factorial was used considering caruncle and cotyledon as the second main factor. Isomers of C18:1 (t6,8 and t12) increase (P < 0.05) in FL and FCNS with MUFA supplementation, fatty acids C20:3 (n-6), C20:3 (n-3), C22:1, C22:5 and C22:6 increase (P < 0.05) in FL and FCNS with EPA+DHA supplementation. In FL there was a tendency to increase for mRNA expression of FATP-1 (P = 0.10) with EPA+DHA supplementation, while mRNA concentration for LPL was greater (P = 0.02) for MUFA supplementation. In placenta DNMT3b and FFAR-4 showed a significant FA x tissue interaction (P < 0.05). These results suggest that FA supplementation during early gestation alters the FA profile in FL and FCNS and changed mRNA concentration of genes involved in the transport of FA and cell metabolism.
