中文摘要：

试验研究了在基础饲料中添加加丽素红、维生素E、磷脂的混合物对血鹦鹉鱼（Cichlasoma syn-spilum×Cichlasoma citrinellum）体色和生理指标的影响.试验设3个处理,分别为对照组（处理A）,0.7%加丽素红与0.3%维生素E组（处理B）,0.7%加丽素红与0.3%磷脂组（处理C）,养殖30 d,测定血鹦鹉鱼体内超氧化物歧化酶（SOD）、丙二醛（MDA）、过氧化氢酶（CAT）、类胡萝卜素、谷丙转氨酶（GPT）及谷草转氨酶（GOT）等指标.结果表明,处理B血鹦鹉鱼亮度和红度显著高于其他组（P〈0.05）;处理B终体重、增重率、特定生长率显著高于其他组（P〈0.05）.3个处理间血鹦鹉鱼肝胰脏、肌肉和皮肤中类胡萝卜素含量差异不显著.血鹦鹉鱼肝胰脏中,处理B SOD、CAT活性显著高于其他组（P〈0.05）,处理B MDA活性显著低于其他组（P〈0.05）.3个处理血清中GOT和GPT含量差异不显著（P〉0.05）.在基础饲料中添加0.7%加丽素红与0.3%维生素E对鹦鹉鱼的体色、生长和抗氧化系统效果较好.

英文摘要：

The experiment was carried out to study the effects of carophyll red mixture on on body color and physiological indexes of blood parrot （Cichlasoma synspilum ×Cichlasoma citrinellum）. Test was divided into three groups including the contrast （treatment A）,0.7% carophyll red and 0.3% vitamin E （treatment B）,0.7% carophyll red and 0.3% phospholipids （treatment C）,after breeding for 30 days,the indexes including SOD,MDA,CAT,carotenoid,GPT and GOT were determined in blood parrot. The results showed that,the degree of brightness and red in treatment B was significantly higher than other groups（P〈0.05）; the final weight,weight gain rate, specific growth rate were significantly higher than other groups（P〈0.05）, too. There were no differences in carotenoid content among liver pancreas, muscles and skin of three treatments. The activity of SOD and CAT in liver pancreas of treatment B was significantly higher than other treatments （P〈0.05）, and the activity of MDA significantly lower than other treatments （P〈0.05）. There were no differences in content of GOT and GPT in serum of three treatments. It was concluded that,the treatment 0.7% carophyll red and 0.3% vitamin E could improve the growth performance,coloring and antioxidant system of blood parrot.
