摘要:

试验旨在研究饲料中添加海洋生物营养强化剂对鸡蛋蛋品质的影响,将600只健康海兰褐壳蛋鸡随机分为两组,分别饲喂普通九洲鸡饲料和含有海洋生物营养强化剂的九洲鸡饲料,对比分析其鸡蛋蛋品质及其功能性营养物质(必需氨基酸、脂肪酸及类胡萝卜素)的变化,试验期56 d。结果显示,试验组海兰褐壳蛋鸡所产鸡蛋(海洋生命蛋)的蛋黄颜色为橙红到鲜红色,蛋黄重/蛋清重为0.424,而普通鸡蛋的蛋黄为黄色和橘黄色,蛋黄重/蛋清重为0.365。海洋生命蛋的总氨基酸含量为13.22 g/100 g,其中各必需氨基酸含量较普通鸡蛋均有不同程度的提高;海洋生命蛋中多不饱和脂肪酸高达30.53%,类胡萝卜素含量达到0.75 mg/枚,而普通鸡蛋仅为0.52 mg/枚;同时,在海洋生命蛋中检测出虾青素,其叶黄素/玉米黄素为1.12,且其有机硒含量为290~490 μg/kg。上述结果表明,添加海洋生物营养强化剂的饲料可较全面地提高鸡蛋的蛋品质。

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
