【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56d。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13.22g/100g,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0.75mg/枚,而普通鸡蛋仅为0.52mg/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290~490μg/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 aim of the experiment was to study the effect of marine biological nutrition fortifier on egg quality. 600 healthy Hailan brown shell laying hens were randomly divided into two groups. The egg quality and its functional nutrients (essential amino acids, fatty acids and carotenoids) were compared and analyzed for 56 days. The results showed that the yolk color of Hailan brown hens was orange red to bright red, the yolk weight / egg white weight was 0.424, while the yolk of ordinary eggs was yellow and orange. Yolk weight / egg white weight was 0.365. The total amino acid content of marine eggs was 13.22 g / 100 g, and the content of essential amino acids was higher than that of common eggs. The contents of polyunsaturated fatty acids and carotenoids in marine eggs were as high as 30.53 and 0.75mg/, while those in common eggs were only 0.52mg/. At the same time, astaxanthin was detected in marine living eggs, its lutein / zeaxanthin was 1.12, and its organic selenium content was 290 ~ 490 渭 g / kg 路kg ~ (-1). The results showed that the egg quality of eggs could be improved by adding marine biological nutrition fortifier.
