Abstract

Unsaturated long chain fatty acids (n-3 FAs) have been proposed in a human diet to reduce the risk of atherosclerosis and therefore the risk of stroke. N-3 FAs also play an important role in retinal and brain tissue development in the neonate. The main natural source of n-3 FA is marine fish. The aim of this work was to create shell egg enriched with n-3 FAs using natural golden marine algae (MA) as a supplement in hen’s diet. Three experiments were conducted: (1) hundred hens from the hybrid Lohmann Brown were fed with diet containing 1.27% MA; (2) hundred hens from the same hybrid were fed with diet containing 1.77% MA; (3) hundred hens were the control group. The duration of the experiments was 4 weeks. Slight enriching of the shell egg yolk at the both groups fed with diet containing MA happened after the end of the second week. The concentration of docosahexaenoic acid (DHA; C22:6, n-3) at the 1st experimental group was 90.3 mg/100 g of egg mass, and 112.1 mg/100 g of egg mass at the 2nd experimental group. The concentration of DHA at the control group was 54.5 mg/100 g of egg mass. After the 3 rd week the concentration of DHA at the 1st group increased to 201.2 mg/100 g of egg mass and to 304.9 mg/100 g of egg mass at the 2 nd group. At that time the concentration of the DHA at the control group remained unchanged. At the end of the 4th week the concentration of DHA reached the maximum level: 224.5 mg/100 g of egg mass at the 1st group and 328.4 mg/ 100 g of egg mass at the 2nd group. The concentration of the DHA at the control group was 51.9 mg/100 g egg mass. It is interested to note that eicosapentaenoic acid (EPA; C20:5, n-3) appeared in low concentrations of 10- 15 mg/100g of egg mass at the end of the 4th week of the experiment at the 2nd experimental group. Keywords - eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), marine algae (MA), omega 3 fatty acids (n-3 FAs).
