This study was conducted in earthen ponds of shrimp hatchery belonging to the Basrah Agricultural Directorate, to find out the effect using of food additives omega-3 and Vitamin E on the performance of the growth and the quality of the produced larvae of the common carp Cyprinus carpio L.. Three treatments were used, the first treatment (T1) represented control without any food additives, the second treatment (T2) contained 5gm.Kg-1 diet of omega-3 fatty acids and the third treatment (T3) contained Vit. E was added at 200 mg.Kg-1 diet. The experiment lasted for 82 days. For each treatment three replicate were used and six common carp brood stock in each replicate. The productive parameters (body weight, weight gain, feed conversion rate, feed efficiency ratio% and specific and relative growth rate%) were measured. Results indicated an improvement in all production parameters and in the feed conversion efficiency of for T2 and T3, compared with the T1. The weight gain (526.39 gm.fish-1), feed conversion rate was 3.61 and feed efficiency ratio was  28.13% for the T2 which showed a significant differences (P<0.05) compared to the control, while T3 did not show significant differences (P>0.05 ) in comparison with both treatments T1 and T2; the specific and relative growth rate for T2 were 0.32%.day-1 and 30.81 %.day-1 respectively showed also a significant differences (P<0.05) compared with the control. These results showed that addition Vit. E to the diet improved the production parameters of common carp larvae better than in omega-3 and control treatments. The study concluded that addition omega-3 fatty acids at a concentration of 5gm Kg -1, and Vit. E at a concentration of 200 mg kg-1 to the diet enhanced the growth rates of common carp and improved larvae production.

The current study aimed to clarify the fatty acids profile in the breeding stock ovaries of common carp (Cyprinus carpio L.) fed on two food additives. The study was carried out in the Shrimp Hatchery which belonging to the Basrah Agricultural Directorate. Three treatment groups were used, the first treatment (T1) represented as control without any food additives, the second treatment (T2) supplemented with 5 g/kg omega-3 fatty acids, and the third treatment (T3) to which vitamin E was added at a concentration of 200 mg/kg. Fishes were randomly distributed in three replicates for each treatment with six of common carp brood stock per replicate. Nine cages were used which placed in earthen pond. Feeding trail lasted from 29 Oct 2018 to 14 Mar 2019. After feeding fish for 82 days, the oil was extracted from gonads by two methods, the first one by Soxhlet apparatus and the second by Accelerated Solvent Extraction (ASE) method. The fatty acid profiles were analyzed using gas chromatograph by GC/MS (Gas Chromatography Mass spectrometry). Results showed that the content of fatty acids in the ovaries of treated fishes in T1, the presence of saturated and unsaturated omega-3 and omega-6 fatty acids, were monounsaturated fatty acid (C19H36:1) scored the highest percentage (52.55%). Fishes in T2 recorded the presence of saturated and unsaturated omega-3 and omega-6 fatty acids were omega-12 (C18H34:12) recorded the highest percentage (50.02%), while T3 fishes showed the presence of saturated and unsaturated fatty acids from the group of omega-6 fatty acids and the unsaturated fatty acid omega-9 (C18H34:9) record the highest percentage (63.24%).In conclusion this study suggested that the content of fatty acids in fish ovaries reflects the composition of fatty acids in the diet.

Lay Summary Research suggests that diet plays a role in the development of inflammatory bowel disease (IBD). Eating more fiber, omega-3 fatty acids, and limiting food additives may lower risk. More research is needed to better understand diet factors that may protect against IBD.

The present study was aimed to investigate the polymorphism of the myostatin gene and its relation with some growth traits,included feed conversion rate and efficiency, protein intake and protein efficiency ratio in 68 specimens of common carp Cyprinus carpio. Sequencing of single nucleotide polymorphism (SNP) showed three genotypes at site T2230C in the myostatin gene. The distribution rates were 5.88, 38.24 and 55.88% for TT, TC and CC respectively, and the variation among them was high significant, the allelic frequency was 0.25 for allele T, while it was 0.75 for C. Effect of the genotype of the myostatin gene was significantly in the feed conversion rate and efficiency, the protein intake and the protein efficiency ratio of the common carp with the variation of the genotypes of myostatin gene, whereas the feed conversion rate was 6.18 , 6.00 and 4.50 at TC , TT and CC respectively. Based on the mentioned results , the positive relation between myostatin gene polymorphism with some growth traits observed in this study may be a useful biomarker in the selection and crossing the genotypes that have achieved the best performance in common carp .

Objective:To conduct a critical review of recent empirical research regarding mood, behaviour and nutrition factors including essential fatty acids, macronutrients, micronutrients and food additives.Method:A literature search of databases Medline, PsycInfo, CINAHL and Embase up to October 2008. The search emphasised empirical research published in the last 10 years and also included older literature. Studies in both adults and children were addressed.Results:Research into omega-3 fatty acids has been substantial but evidence for their potential in treating mood and behaviour is modest. In comparison, there has been much less research into carbohydrate and protein intakes and little evidence for their ability to influence mood and behaviour. Recent trials with food additives suggest their removal from the diet may benefit susceptible children with hyperactivity disorders. Micronutrient supplementation appears to improve mood only in those who were initially deficient in micronutrients.Conclusions:More stringent research designs such as longitudinal studies and the use of biologically inert placebos within randomised controlled trials are needed before supplemental use of omega-3 fatty acids to treat disorders of mood and behaviour can be recommended. Caution is advised regarding the indiscriminate use of diets free of artificial food additives in managing hyperactivity disorders, as they may place an undue burden on individuals and their families. Should omega-3 fatty acid supplementation or the elimination of certain food additives be established as effective, they may provide cost-effective, accessible and well-tolerated adjuncts to standard psychiatric treatments for mood and behavioural disturbances.

Serum Homocysteine

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.
