إنتاج بيض غني بالأحماض الدهنية-الأوميجا 3 و مضادات الأكسدة لتحسين الصحة العامة

Abstract EN

The change in dietary habits because of the modern lifestyle in the Arab gulf region, in general, led to an increase in the risks of obesity, diabetes, atherosclerosis, coronary heart disease, and an increase in cholesterol and blood pressure, which reduces the citizen's productivity and increases the cost of health care.

recent results indicated that eggs produced in the Arabian gulf region are poor in their content of omega-3 fatty acids and selenium.

that is why this study was conducted in the laboratories of king Abdulaziz University, Jeddah, Saudi Arabia, which seeks for the first time, aimed to combine the increase in the content of omega-3 fatty acids and selenium in table eggs as an appropriate means to reduce these risky diseases.

for this purpose, 120 laying hens were distributed among four dietary treatments, including feed without oils addition (0% oil added, treatment 1, control), 4% of soybean oil (treatment 2), 4% of linseed oil (treatment3), 4% of linseed oil, and 0.

2 mg/kg feed of organic selenium (treatment 4).

it was observed that the use of flax oil led to an increase in economic efficiency and a reduction in triglycerides, cholesterol in the blood, and egg yolks, and an increase in the total polyunsaturated fatty acids.

and this provides evidence of reduced atherogenic, thrombogenic indices and reduced risk of hypercholesteremia markedly compared to the oilunsupplemented diet (control).

in addition, the deposition of omega-3 in eggs increased significantly.

furthermore, adding linseed oil with selenium increased economic efficiency, egg quality, shell quality, HDL- cholesterol, selenium concentration in eggs, and antioxidant status.

these new findings indicate for the first time that it is possible to produce eggs rich in omega-3 and selenium using 4% of flax oil and 0.2 mg of organic selenium, which improves the quality of eggs and their nutritional and marketing value in the Gulf region.
