饲料中添加乌贼肝粉和鱼浆蛋白对中华鳖生长性能和肝功能的影响

研究饲料中添加乌贼肝粉和鱼浆蛋白对中华鳖生长和肝功能的影响.共设计3个实验组,即对照组（白鱼粉组）、乌贼肝粉组和鱼浆蛋白组.3种实验饲料的营养组成相近,其中乌贼肝粉组和鱼浆蛋白组的饲料分别用乌贼肝粉和鱼浆蛋白取代对照组饲料中5%的白鱼粉.用3种饲料分别养殖中华鳖稚鳖8周.结果发现,3个实验组稚鳖的摄食率和生长速度没有显著差异.乌贼肝粉组的饲料系数与对照组无显著差异,但鱼浆蛋白组的饲料系数显著高于对照组和乌贼肝粉组.乌贼肝粉组的干物质和脂肪消化率显著高于对照组,蛋白消化率与对照组无显著差异；鱼浆蛋白组的干物质、蛋白和脂肪消化率均显著高于对照组.乌贼肝粉组稚鳖的肝谷草转氨酶（glutamic-ox...

Summary:研究饲料中添加乌贼肝粉和鱼浆蛋白对中华鳖生长和肝功能的影响.共设计3个实验组,即对照组（白鱼粉组）、乌贼肝粉组和鱼浆蛋白组.3种实验饲料的营养组成相近,其中乌贼肝粉组和鱼浆蛋白组的饲料分别用乌贼肝粉和鱼浆蛋白取代对照组饲料中5%的白鱼粉.用3种饲料分别养殖中华鳖稚鳖8周.结果发现,3个实验组稚鳖的摄食率和生长速度没有显著差异.乌贼肝粉组的饲料系数与对照组无显著差异,但鱼浆蛋白组的饲料系数显著高于对照组和乌贼肝粉组.乌贼肝粉组的干物质和脂肪消化率显著高于对照组,蛋白消化率与对照组无显著差异；鱼浆蛋白组的干物质、蛋白和脂肪消化率均显著高于对照组.乌贼肝粉组稚鳖的肝谷草转氨酶（glutamic-oxalacetic transminase,GOT）活性显著低于对照组,血清谷丙转氨酶活性（glutamic-pyruvic transminase,GPT）显著高于对照组.鱼浆蛋白组肝和血清的 GOT 和 GPT 活性与对照组均无显著差异.3个实验组稚鳖的血清三酰甘油和总胆固醇含量没有显著差异.实验结果表明,饲料中添加5%的乌贼肝粉有可能对稚鳖肝造成轻微损伤；饲料中添加5%的鱼浆蛋白将降低饲料的利用率,但对稚鳖肝功能没有显著影响.
Bibliography:Squid liver meal is an attractant used in aquafeed widely. However, the fatty acid rancidification and high content of cadmium in squid liver meal may affect the animal health. Soluble fish protein concentrates are produced from the waste water of fish meal production, and have many attractive materials. Chinese soft-shelled turtle, Pelodiscus sinensis, is an important economic animal in China, and fishmeal is one main protein resource in turtle feed. Squid liver meal and soluble fish protein concentrates maybe the alternatives to fishmeal in turtle feed because of their high protein content and low price. No study has reported the effects of squid liver meal on health of turtle and the utilization of soluble fish protein concentrates in turtle feed. Therefore, this experiment has the aim of exploring the effects of the supplementation of squid liver meal and soluble fish protein concentrates on the growth and liver function of P. sinensis. Three experimental groups were designed, control group （white fishmea
