肌醇对奥尼罗非鱼生长、肝脏和肌肉脂肪含量及血清生化指标的影响
Effects of dietary inositol on growth, liver and muscle fat content and biochemical indices of blood serum in tilapia (Oreochromis niloticus×Oreochromis aureus)
摘要
Abstract
[Objective ]This experiment was conducted to determine the effect of dietary inositol on growth performance of tilapia (Oreochromis niloticus×Oreochromis aureus) ,to provide reference for controlling fatty liver disease of tilapia and to increase its breeding benefit. [ Method ]The feed added with inositol (0, 0.01, 0.02, 0.03 and 0.04%) was used for breeding tilapia. After 70 days of breeding, the blood in heart was collected to determine the chemical indices of serum using PUZS-300 full-automation analyzer, and the back muscle and liver were collected to determine the fat content after drying. [Result]The results showed that when tilapia feed was added with 0.03% inositol, the weight gain rate of tilapia attained the peak value (5196.30%), while the feed conversion ratio, HIS and fat content in liver were relatively low as 1.47, 3.31 and 39.20%, respectively. In blood serum, the content of cholesterol was found highest (3.96 mmol/L), while the contents of triglyceride and low density lipoprotein were lower, as well the activities of glutamic-oxalacetic transaminease, glutamic-pyruvic transaminase, lactic dehydrogenase and bile acid were lower. [Conclusion]It has been suggested that the supplementation of inositol shall be controlled in feed of tilapia and the supplementation time of insitol shall be selected according to the actual demand at different growth durations, physiological status and environment conditions.关键词
