The effect of dietary menhaden meal (MM) on production and egg yolk lipids of commercial White Leghorn hens was studied for 350 d. One hundred and ninety-two birds were given a corn-wheat-soybean diet that contained either 0, 4, 8, or 12% MM. Analysis of the egg yolks at four periods in the laying cycle (162, 211, 254, and 289 d) was performed on the fresh and stored (4 wk at 4 °C, [Formula: see text]) egg yolks. Sensory evaluation was performed on fresh eggs collected at the end of the laying cycle (448 d).Production whether measured as hen-day or hen-housed, increased linearly with the inclusion of MM in the diets. The level of eicosapentaenoic and docosahexaenoic acids increased 10- and 2.6-fold to give levels of 9 and 95 mg yolk−1, respectively. Storage had no effect (P > 0.05) on these parameters. Sensory data suggested that the level of MM in the diets of laying hens should be between 4 and 8% in order to avoid off-flavours in eggs.

Ground Flaxseed

The purpose of the study was to investigate the potential of feeding laying hens with ground flax, a combination of flax cake and flax oil in the production of eggs enriched with omega-3 fatty acids. The experiment was set up using 192 laying hens divided into 4 groups: the control group; a group fed with flaxseed cake (10%) + flaxseed oil (2%); a group fed with 5% ground flax, and a group fed with 10% ground flax. Each group had 8 cages housing 6 laying hens, that is, a total of 48 laying hens per group. The Haugh unit values, fat content, Thiobarbituric acid reactive substances (TBARS) values, yolk color parameters and yolk fat content were measured at the end of 5th and 10th weeks of the trial. The results of this study showed that omega-3 enriched dietary treatments had an impact on the results obtained for the amount of total fat in the yolk, and the results of the TBARS test. The results presented show that the average amounts of alpha linoleic (ALA) and docosahexaenoic (DHA) fatty acids in egg yolk were influenced by the nutritional treatments, i.e. the laying hens that were fed with mixtures enriched with 5% and 10% ground flaxseed, as well as 10% flaxseed cake + 2% flaxseed oil, had significantly (P<0.05) higher amounts of ALA and DHA in their egg yolk compared to the laying hens in the control group.

Enriching table eggs with certain nutrients such as omega-3 fatty acids is an ongoing topic. Therefore, the aforementioned research was carried out with the aim of examining the possibility of feeding laying hens with ground flax seed, flax cake and flaxseed oil and their influence on the ratio of omega-6 and omega-3 fatty acids of table eggs, as well as on certain production parameters. The experiment was set up in a production facility with 192 consuming laying hens 27 weeks old. The laying hens were divided into 4 groups: control group; group fed with flax cake (10%) + flax oil (2%); a group fed with 5% ground flax and a group fed with 10% ground flax. Each group had 8 cages with 6 laying hens, a total of 48 laying hens per group. The production parameters presented in this paper are as follows: number of eggs per laying hen , egg weight and yolk weight. Egg quality indicators were determined at the end of the 5th and 10th week from the start of the experiment, namely: pH of egg white and yolk, polyunsaturated and saturated fatty acids ratio, as well as omega-3 and omega-3 fatty acids ratio. The results of the study showed that the inclusion of flax cake, flax oil and ground flaxseed had no negative effects on the shown production parameters and that there was a positive effect of these nutrients on the ratio of omega-6 and omega-3 fatty acids in table eggs.

The experiment was conducted to find of the effects of using sardine oil in rations on the performance of laying hens and quality eggs, especially the omega-3 fatty acids content in the chicken egg. There were four group of in this experiment: L0 (commercial feed) as control treatment, L1 (L0+5% sardine oil), L2 (L0+10% sardine oil) and L3 (L0+15% sardine oil). Data analyzed Completely Randomized Design (CDR) and each group consisted 24 quails. Results of this research showed that there are has a significant (P&lt;0,05) effects on laying hens performance productions. The used of sardine oil in rations significantly influenced the omega-3 fatty acids and cholesterol content (P&lt;0,05). The omega-3 fatty acid content on the egg consumption from the used of sardine oil in rations was highly (P&lt;0,05) and the cholesterol content lower (P&lt;0,05) than not the used of sardine oil in rations. The result showed that used of sardine oil in rations made the performance of laying hens better than the used of control rations. The increasing of sardine oils usage in rations to increased the omega-3 fatty acids content and to decrease of cholesterol content in the chicken egg. It was concluded that using sardine oil in the rations gave effect on the good performance of laying hens.

AbstractIn the US farmers often market pastured poultry eggs for a premium price, claiming animal and human health benefits. We examined how moving pastured hens to forage legumes or mixed grasses influenced hen (Gallus gallusL.) egg omega-3 fatty acids and concentrations of vitamins A and E. We also compared the eggs of the pastured hens to those of hens fed a commercial diet in cages. We used a cross-over design to compare pasture species: 75 sister hens were assigned to one of three pasture treatment groups: (1) alfalfa (Medicago sativaL.), (2) red and white clover (Trifolium pretenseL. andTrifolium repensL.) or (3) mixed cool season grasses. Groups were rotated to all three pasture treatments, each for 2 weeks and supplemented with 70 g commercial hen mash bird−1day−1. Pasture botanical composition, forage mass, leaf to total ratio and plant fatty acid composition were compared among pasture treatments. Eggs of the pastured hens were compared to eggs of 50 sister hens that were fed only commercial hen mash in cages for the entire 6 weeks. Forage parameters varied somewhat, but did not explain plant linolenic acid variation. Seventeen of the 18 quantified egg fatty acids, and vitamin A concentrations did not (P<0.05) differ among the three pasture treatment groups. Eggs of the hens that foraged grasses had 23% more (P<0.0001) vitamin E than eggs of hens that foraged clover. Compared to eggs of the caged hens, pastured hens' eggs had twice as much vitamin E and long-chain omega-3 fats, 2.5-fold more total omega-3 fatty acids, and less than half the ratio of omega-6:omega-3 fatty acids (P<0.0001). Vitamin A concentration was 38% higher (P<0.05) in the pastured hens' eggs than in the caged hens' eggs, but total vitamin A per egg did not differ. At the end of the experiment, pastured hens weighed 14% less and averaged 15% lower hen-day egg production than caged birds (P<0.0001). Results suggest that grass pastures may enhance vitamin E in eggs of pastured hens more than clover, and pastured hens supplemented with commercial mash will produce eggs with significantly more vitamin E and total omega-3 fatty acids compared to eggs from caged hens fed only commercial hen mash. Pastured hens may have lower body weight and egg production than caged hens, unless they are supplemented adequately to meet their dietary energy and crude protein needs.

Abstract. Background: Elevated homocysteine levels and malnutrition are frequently detected in hemodialysis patients and are believed to exacerbate cardiovascular comorbidities. Omega-3 fatty acids have been postulated to lower homocysteine levels by up-regulating metabolic enzymes and improving substrate availability for homocysteine degradation. Additionally, it has been suggested that prevention of folate depletion by vitamin E consumption decreases homocysteine levels. However, data on the effect of omega-3 fatty acids and/or vitamin E on homocysteine levels and nutritional status have been inconclusive. Therefore, this study was planned to examine the effect of combined supplementation of fish oil, as a source of omega-3 fatty acids, with wheat germ oil, as a source of vitamin E, on homocysteine and nutritional indices in hemodialysis patients. Methods: This study was a randomized, double-blind, placebo-controlled trial. Forty-six hemodialysis patients were randomly assigned to two equally-sized groups; a supplemented group who received 3000 mg/day of fish oil [1053 mg omega-3 fatty acids] plus 300 mg/day of wheat germ oil [0.765 mg vitamin E], and a matched placebo group who received placebo capsules for 4 months. Serum homocysteine and different nutritional indices were measured before and after the intervention. Results: Twenty patients in each group completed the study. At the end of the study, there were no significant changes in homocysteine levels and in the nutritional indices neither in the supplemented nor in the placebo-control groups (p > 0.05). Conclusions: Fish oil and wheat germ oil combination did not produce significant effects on serum homocysteine levels and nutritional indices of hemodialysis patients.
