Abstract:

The experiment was aimed to study the effects of adding marine biological fortified material to diets on egg quality.600 healthy Highland Brown egg-shell chicken were chosen and randomly divided into control group and experimental group. The chicken in control group were fed with Jiuzhou diets and that in experimental group were fed with Jiuzhou diets supplemented with marine biological fortified material,and the egg quality and nutrient components such as amino acids,fatty acids and carotenoids were compared.The experiment lasted for 56 d. The results showed that the yolk color of marine vitalized egg was orange-red to bright red,and the ordinary yolk color was yellow. The ratio of yolk weight to egg white weight of the marine vitalized egg was 0.424,which was much higher than that of ordinary egg (0.365).The total amino acids content of the marine vitalized egg achieved 13.22 g/100 g,and the contents of essential amino acids were higher than ordinary egg in different degrees. The percentage of polyunsaturated fatty acids of the marine vitalized egg was 30.53%,meanwhile,the content of carotenoids was 0.75 mg per egg,which were significantly higher than that in ordinary egg (0.52 mg per egg)(P<0.05).The astaxanthin was only detected in the marine vitalized egg,and the ratio of lutein to zeaxanthin was 1.12. The content of organic selenium was about 290 to 490 μg/kg in the marine vitalized egg. These results suggested that marine biological fortified material supplenmentary diets could comprehensively improve the egg quality and nutrition.

Key words: marine biological fortified material; amino acids; fatty acids; carotenoids
