The concentration of selenium (Se) in food is in many countries too low and the ratio between omega-6 and omega-3 fatty acids too high implying more non-communicable diseases, e.g. cancer, cardiac disease, impaired immune defense, pain, enhanced non-infectious inflammatory response. Meat from animals supplemented with Se and omega-3 fatty acids makes a good source of these nutrients in human nutrition. The worldwide demand for several nutrients is increasing, and food with optimal composition is required. The objective of the present study was to produce chicken meat especially high in Se and with a favorable ratio between omega-6 and omega-3 fatty acids. Sixty newly hatched chickens were fed wheat-based diets containing 40 g rapeseed oil/kg, 10 g linseed oil/kg and varying amounts of selenium enriched yeast for three weeks, resulting in meat with a favorable ratio between omega-6 and omega-3 fatty acids and with selenium concentration ranging from 0.2 to 0.6 mg/kg. This meat would be expected to give health benefits both in prophylactic and therapeutic contexts. It represents a better strategy for increasing the intake of Se and very long chain omega-3 fatty acids at a population basis rather than relying on Se supplements or only on fish resources that are already overexploited and can not cover EPA and DHA requirements (for ensuring optimal health) for more than a fraction of the world’s total population. The meat from the highest Se supplementation treatment groups might be useful for some groups of patients (e.g. with ischemic pain) who might benefit from especially high Se intake.

Time Of Feeding

Interest on the enrichment of eggs and poultry meat with omega-3 fatty acids (n-3 FA) has increased given their important role in human metabolism. The inclusion of n-3 FA into eggs and poultry meat is achieved by feeding ingredients such as flaxseed, fish oil, fish meal, marine algae and canola to birds. However, problems in various production parameters and sensory quality of eggs and meat may arise. The former possibly caused by antinutritional and physiological effects and the latter influenced by the interaction of volatile substances. Possible increases in formulation costs also deserve attention. Strategies to ameliorate these undesirable effects include limiting the inclusion levels of n-3 FA sources, time of feeding, mixing different n-3 FA sources in commercial rations, and including high levels of vitamin E along with high-quality ingredients. A mild heat treatment may eliminate some of the drawbacks of feeding flaxseed to birds. Key words: Omega-3, flaxseed, flax, menhaden oil, eggs, chicken meat

Cardioprotective action of omega-3 polyunsaturated fatty acids such as eicosapentaenoic and docosahexaenoic acid in fish and α-linolenic acid in plants was demonstrated in primary and secondary clinical trials. Fish oil therapy causes a marked decrease in serum triacylglycerol and very low density lipoprotein levels and increases moderately high density lipoprotein levels without any adverse effects. Omega-3 fatty acids decrease slightly, but significantly blood pressure, enhance endothelial function, they have anti-aggregator, anti-thrombotic and anti-inflammatory effects as well. These beneficial effects are in connection with modification of gene transcription levels of some key molecules such as nuclear factor-κB and sterol element binding receptor protein-1c, which regulate for example expression of adhesion molecules or several receptors involved in triglyceride synthesis (hepatocyte X receptor, hepatocyte nuclear factor 4α, farnesol X receptor, and peroxisome proliferator-activated receptors). On the basis of these observations, the supplementation of the diet with omega-3 fatty acids (fish, fish oil, linseed, and linseed oil or canola oil) is advisable in primary and secondary prevention.

Diet Supplement

This study aims to evaluate an effect of pig diet supplementation with ethyl esters derived from linseed oil with a high content of alpha-linolenic acid (ALA) on the fatty acids profile of meat. The study was conducted on Polish Landrace fatteners supplemented for a period of 7 weeks (control and experimental groups of 8 animals each, 16 in total). After this period, loin (Longissimus dorsi) and ham (Biceps femoris) samples were collected for laboratory analysis, including basic composition (fat, protein, ash, dry matter) and fatty acids (FAs) profile. The supplementation caused a significant increase in the level of ALA acid, decrease in the content of saturated fatty acids (SFAs), increase in unsaturated FAs level, and resulting decrease in the ratio of n-6/n-3. The indices of atherogenicity and thrombogenicity were beneficially altered in the experimental groups. It can thus be supposed that meat enriched this way may be considered as an interesting choice for consumers who are aware of the importance of diet consumed.

Preliminary Study

Fatty acids from the omega-3 family are an important element of both human and animal diets. Their activity involves a range of functions for the functioning of a whole organism, and their presence in animal diets can be considered as a means for animal origin product enrichment for human benefit or as compounds profitable for an animal’s health status. The aim of this preliminary study was to compare the effect of supplements rich in omega-3 fatty acids (linseed oil, linseed oil ethyl esters, and fish oil) in rat feed on the fatty acid profile of their intramuscular and perimuscular fat. The results demonstrated beneficial changes in fatty acid profiles (a decrease in saturated acids, an increase in unsaturated ones, i.e., omega-3 acids share) of examined tissues in the case of all supplements however, particular attention should be paid to linseed oil ethyl esters, which significantly increased the content of all omega-3 acids. Supplementation of animal diet with linseed oil ethyl esters may be beneficial for both animals, as omega-3 fatty acids exhibit profitable properties related to an animal’s health status and productivity, and humans who consume such enriched products.

PICO question Does treatment with a non-steroidal anti-inflammatory drug (NSAID) with supplementation of marine-derived  omega-3 fatty acids (n-3FAs) compared to the NSAID alone, result in an increased ability to exert force by the osteoarthritic limb(s) of dogs or alleviate other measures of osteoarthritis?   Clinical bottom line Category of research question Treatment The number and type of study designs reviewed Two prospective, block-randomised, clinical trials Strength of evidence None Outcomes reported Kwananocha et al. (2016) investigated administration of carprofen supplemented with marine-derived n-3 FAs, to carprofen alone, administered over 4 weeks. Vijarnsorn et al. (2019) investigated administration of firocoxib supplemented with n-3FA, to firocoxib alone, for 4 weeks.  There were no statistical differences between treatment groups at week 2 and week 4 post-treatment for either study. Both studies also reported orthopaedic assessment score (OAS) based on scoring the extent of patient lameness and pain in the affected joint. There were no statistical changes in OASs between treatment groups at week 2 or week 4 post-treatment for either study Conclusion There is no evidence that marine-derived n-3 FAs provide additional benefit when used as adjunctive agents with NSAIDs for the treatment of canine osteoarthritis   How to apply this evidence in practice The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources.

AbstractFlax (Linum usitatissimum L.) is an important source of oil rich in omega–3 fatty acids (especially α-linolenic acid accounting for > 50%), which is proven to have health benefits and utilized as an industrial raw material. α-Linolenic acid is a polyunsaturated fatty acid that readily undergoes oxidative transformation. Autoxidation of α-linolenic acid is the principal process contributing to the development of off-flavors, loss of color, and alteration in the nutritional value of linseed oil. However, there is huge a demand on the market for oils having different compositions of fatty acids, including the linseed oil characterized by improved stability. For this purpose, a complete diallel cross was performed in this study using six flax genotypes varying in the fatty acid content to estimate the genetic parameters. The analysis of variances carried out for the studied traits (content of oleic, linoleic and α-linolenic acid) indicated large differences among the genotypes. Variances due to GCA were much higher in magnitude than those related to SCA for the content of linoleic and α-linolenic acid, which indicated the superiority of additive gene effects in determining the inheritance of these traits. The nonadditive gene action played an important role for oleic acid content, since the magnitude of SCA effect was almost two times higher than GCA effect. The parental lines of linola (Linola KLA and Linola KLB) exhibited the highest concentration of favorable alleles for the two traits (high content of linoleic acid and low content of α-linolenic acid) and were thus found suitable for a continuous improvement program. On the basis of the SCA effect, five cross combinations, were found to be promising F1 hybrids for use as a source population for further selection, in order to achieve fatty acid changes in linseed. These combinations allow selecting varieties with 1:1 and 2:1 ratio of omega–6:omega–3 fatty acids for producing oil with an extended shelf life for food products.

An experiment was conducted to study the effect of inclusion of different feed oil sources rich in omega-3 fatty acids on the production performance of Japanese quail. The feeding trial was conducted in 360 numbers of day old Japanese quail broiler chicks for five weeks (0 - 5 week) with different oil sources-Palm oil - PO, Linseed oil-LO and Sardine Fish oil-SO with various inclusion levels of different sources of omega-3 fatty acids (T1-PO 4%; T2 LO 4%:T3 LO 3% + SO 1%; T4 LO 2% +SO 2%; T5 LO 1% + SO 3%; T6 SO 4%) with six replicates with ten birds in each replicate. All the diets were isocaloric and isonitrogenous. Different oil sources (palm oil/linseed oil/sardine oil) in the Japanese quails ration had no significant effect on average daily gain, feed consumption and feed conversion efficiency
