“…In view of the present results we have arbitrarily chosen the dietary concentration of 0·75 % CLA as the optimum for laying hens, to enrich effectively hen egg yolks with CLA. The present results are generally consistent with the earlier findings and were thoroughly discussed and elucidated by Schäfer et al 37 , Raes et al 38 , Szymczyk & Pisulewski 28 , and more recently by Shang et al 39 and Cachaldora et al 40 .…”

The objective of this study was to evaluate potential anti-atherogenic properties of hen eggs enriched naturally with conjugated linoleic acid (CLA) isomers (cis-9, trans-11 and trans-10, cis-12). Eighteen apoE and LDL receptor double-knockout mice (apoE/LDLR 2/2 ), at the age of 4 months with pre-established atherosclerosis, were randomly assigned to three experimental groups (n 6) and fed AIN-93G-based diets for the next 2 months. The experimental diets were: AIN-93G þ CLA-free egg-yolk powder (control); AIN-93G þ CLA-free egg-yolk powder þ 0·1 % CLA (CLA-supplemented eggs); and AIN-93G þ CLA-enriched egg-yolk powder, providing 0·1 % CLA (CLA-enriched eggs). For assessment of anti-atherogenic properties of CLA-enriched or CLA-supplemented eggs the following criteria were used: (1) serum lipid profile; (2) development of atherosclerosis; and (3) composition of atherosclerotic plaque. CLA-enriched eggs, compared with CLA-supplemented eggs, reduced significantly (P,0·05) total plasma cholesterol in the mice. At the same time, both CLA-supplemented eggs and CLA-enriched eggs tended to decrease the size of atherosclerotic plaque in aortic roots of mice. Most importantly, atherosclerotic plaques of mice fed CLA-enriched eggs showed significantly (P, 0·05) reduced number of atherogenic macrophages and increased area occupied by smooth muscle cells in atherosclerotic lesions. In conclusion, CLA-enriched eggs exerted an anti-inflammatory effect more effectively than CLA-supplemented eggs. This anti-inflammatory effect can be considered their major functional claim that warrants further exploitation. Conjugated linoleic acid: apoE/LDLR 2/2 : Atherosclerosis: Composition of aortic plaque Conjugated linoleic acid (CLA) is a collective term to describe a class of positional and geometric isomers of linoleic acid (cis-9, cis-12 C18 : 2n-6) in which the two double bonds are separated by a single C-C bond, but not by a methylene group (-CH 2 -). CLA isomers are intermediate products of bacterial biohydrogenation of dietary unsaturated fatty acids in the rumen, and are mainly found in fat of ruminant milk and meat 1 .In the last 10 years, extensive research have indicated that commercial CLA preparations, fed to laboratory animals, showed several health-related properties, including antiadipogenic 2 -5 , anti-carcinogenic 6 -8 , anti-atherogenic 9 -15 and anti-inflammatory 16,17 effects. Consequently, in view of the evident health-related properties associated with CLA isomers and also in line with the concept of functional foods 18 , attempts have been made to enrich animal-derived foods with CLA isomers through animal nutrition strategies. Indeed, these attempts resulted in production of functional food such as CLA-enriched milk (butter, cheese), ruminant and non-ruminant meat, as well as eggs 19,20 -23 .Except for our preliminary studies 24 , there have been no data available on whether eggs, enriched naturally with CLA isomers, and fed to laboratory animals, could have healthrelated properties similar to those described f...

“…The type of diet did not affect egg production traits. Cachaldora et al (2005) indicated that when hens were fed diets with 2 levels of fish oil (0 and 17 g/kg), egg production characteristics were not affected. These data are in agreement with results found by Carrillo et al (2005) who proved that when laying hens were fed diets with red crab meal (a source of omega-3 fatty acids), egg production was not influenced by dietary treatment.…”

This study was conducted to show that dietary supplementation of fish oil, effects growth performance, egg quality and decreases yolk cholesterol in laying hens. One hundred twenty Bovans white hens at their 23rd week of age were housed individually in cages in an open sided house. The birds were kept under a 16 hr light: 8 hr dark lighting schedule (lights on between 06:00 and 22:00 hr). Birds were randomly divided into five dietary treatments and 3 replicates in each (8 birds per replicate); the first treatment group was control and given 0% fish oil + 5% vegetable oil, the second treatment given 1.25% fish oil +3.75 % vegetable oil, the third treatment given 2.5% fish oil + 2.5% vegetable oil, the fourth treatment given 3.75% fish oil + 1.25% vegetable oil and the fifth treatment given 5% fish oil + 0% vegetable oil. The birds were raised for 12 weeks from 23 weeks of age to evaluate the effect on growth, egg quality, yolk cholesterol and linoleic and linolenic fatty acids content in yolk. Body weight gain was increased significantly (P ≤ 0.05) by 9.2% in birds fed diets content 3.5% fish oil, as compared with those fed on control diet and feed intake was decreased significantly (P ≤ 0.05) by 26.4% in birds fed diets content 5% fish oil, as compared with those fed on control diet. Also, egg weight was decreased significantly. Due to fish oil egg quality were improved. Interestingly, yolk cholesterol was decreased significantly (P ≤ 0.05) by 14.5% in birds fed diets content 3.5% fish oil, as compared with those fed on control diet. Furthermore, it was observed significantly increase (P ≤ 0.05) in linolenic fatty acid content in yolk by 30.5% in birds fed diets content 3.5% fish oil, as compared with those fed on control diet. In conclusion, feeding fish oil deceased feed intake, egg weight and egg production on the other hand, increased unsaturated fatty acids and cholesterol content in yolk in laying hens.

“…The available data revealed the inefficaciousness of oil supplements on eggshell quality. It was previously reported that dietary sunflower oil supplementation did not affect eggshell weight (Ceylan and Çufadar, 2018), thickness (Cachaldora et al, 2005), and strength (Dong et al, 2018) (Promila et al, 2017). The conflicting results were indicated to have been linked with the dietary oils' fatty acid contents (Ding et al, 2017).…”

This experiment was performed to investigate the effect of flaxseed oil and sunflower oil supplementation on the production performance, egg quality, and egg sensory characteristics in laying hens under density stress. A totaly of 144 Atak-S hens were used. The animals were assigned into 2 groups as stressed and unstressed. These were allocated into three subgroups as those who were fed with basal diet, diets containing 2% sunflower oil, and 2% flaxseed oil. Density stress was applied to those in the stress group by providing an area of 357 cm2 per hen. Egg production performance, average egg weight and egg mass, eggshell weight, eggshell thickness, eggshell strength, Haugh unit, albumen height, yolk color and sensory carateristics of the eggs were measured. Flaxseed oil reduced egg production and egg mass in those who are unstressed. On the contrary, it increased egg production and egg mass in the stressed groups. Sunflower oil was found to increase the average egg weight and egg mass in all groups. It was observed that when sunflower oil was added to the diets of the stressed chickens, the yolk color index decreased. In addition, it was determined that the eggs of the nostressed hens taste better than the stressed chickens. It was determined that flaxseed oil added to the diets increased the sensory quality of the eggs in both stressed and non-stressed groups. Therefore, incorporation of flaxseed and sunflower oil into the diets of layer hens can be recommended.
