Omega-3 fatty acids in order to investigate effects on human health, review of previous studies and outlined in this study, the results of previously conducted research on omega-3 fatty acids and mainly cardiovascular disease and hypertension, including Alzheimer, depression, schizophrenia, astima, stroke, rheumatoid arthritis, osteoporosis and prostate, breast, bowel and lung cancer is of vitual importance in the preventation and treatment of of many diseases and showed that no occurance of significant side effects also concluded that this natural functional compounts of the name of results can be used safely in the preventioan and treatment of the aforemetion ed diseases.

This study was conducted to determine the effects of different levels (0, 200, 250 and 300 mgCu/kg) of dietary cupper supplementation on some minerals (Cu, Zn, Fe, Mg, Ca and P) found in liver, breast and thigh tissues of laying hens. For this aim, 38-week old total 96 Lohman laying hens as 6 replicate cages each containing 4 hens, were allocated randomly to one of four dietary treatments. Treatment groups were fed diets containing (16.5% crude protein, 2670 kcal/kg ME) a standard commercial layer diet (Control), basal diet plus 200 (B-1), 250 (B-2) and 300 mgCu/kg (B-3) for 12 weeks. Dietary cupper supplementation did not affect calcium levels but altered levels of investigated other minerals (Cu, Zn, Fe, Mg and P) in all tissues (liver, breast and thigh) (P<0.001). The addition of increasing levels of cupper into diets increased cupper and phosphor contents (P<0.001), however decreased zinc levels significantly (P<0.001) in all inspected tissues. The addition of cupper into diets increased very significantly iron levels in thigh and breast tissues while reducing iron level in liver (P <0.001). The differences between groups in terms of magnesium contents in the liver and thigh tissues were found significantly (P<0.001), and dietary cupper supplementation did not change magnesium level in thigh meat. As a result, the addition of cupper into rations for laying hens increased cupper content and reduced levels of zinc and iron in liver, the main storage site cupper, iron and zinc. This situation shows that there is such a negative relationship between these minerals. [ABSTRACT FROM AUTHOR]

This study was carried out to determine the effects of lovastatin supplementation on laying performance, egg quality, yolk lipid profile and some serum parameters in Lohmann LS white commercial laying hens reared in poultry houses of Food and Livestock Application and Research Center of Ataturk University. In this experiment, Lohmann layers (n=48, 46 wks of age) were randomly divided into two groups such as control (C) fed with basal diet and treatment (L) group fed with diet including 0,0059 % of lovastatin. After one week of the adaptation period, experiment lasted for five weeks. During the experimental period, hens were fed as ad-libitum and water through nipples was available for all the times. Lovastatin supplementation increased feed consumption (FC) and feed conversion ratio (FCR). Except for yolk color, other egg quality traits were not affected by diet including 0,0059 % of lovastatin. Hens fed with treatment diet had greater triglyceride and phosphatidyl serine values than hens fed with basal diet. Differences between the groups in terms of the levels of egg yolk and serum cholesterol were not significant in present study. These differences could be attributed to short experimental period and low lovastatin added to basal diet of hens. In conclusion, further studies should be conducted to clarify the effects of lovastatin supplementation on laying performance, egg quality, yolk lipid profile and some serum parameters in laying hens fed with diets including lovastatin at different levels during long feeding period.

This study was carried out to determine the effect of dietary rosehip seed (RS) supplementation into layer diets at different levels on performance, egg quality traits and some serum parameters. A total of 72 Lohmann layers, 46 weeks old, were divided into three treatment groups. The control group was fed with commercial layer diet (K), and the other two groups were fed with basal diet + 10% ground rosehip seeds (K1) and basal diet + 15% ground rosehip seeds (K2) for 12 weeks. The water and feed were provided as ad-libitum during the trial. The rosehip seed supplementation level at 15% into layer diets increased the feed consumption and egg yield (p<0.05), and decreased the damaged egg ratio. Though some egg quality traits such as the yolk colour, shell thickness and shell weight increased (p<0.05) in eggs from K2 group, there were no significant differences (p> 0.05) among the groups in respect to other egg quality traits such as shape index, shell strength, albumen and yolk indexes and Haugh unit values. Total cholesterol, cholesterol esters, free fatty acids and triglyceride contents in the egg yolks from treatment groups were not affected by dietary treatments (p> 0.05). Serum parameters such as albumin, total cholesterol, VLDL, triglyceride and ALT values increased (p <0.05) with the RS supplementation at level of 15% into layer diet. Results showed that rosehip seed supplementation into layer diets may be beneficial to improve egg quality traits especially such as shell thickness and to decrease damaged egg ratio. But further investigations are needed to clarify the use of rosehip seed in layer diets and its effects on performance, egg quality and serum parameters. [ABSTRACT FROM AUTHOR]
