6 : 05 EFFECTS OF DIETARY MELAMINE ON GROWTH PERFORMANCE, PHYSIOLOGICAL RESPONSE, HISTOPATHOLOGY AND TISSUE RESIDUE IN JAPANESE SEA BASS (LATEOLABRAX JAPONICUS) LIU Hai-Yan,2,4, ZHENG Yin-Hua, QIN Yu-Chang, XUE Min, WU Xiu-Feng, YUN Biao and GUO Li-Ya,3 (. Feed Research Institute, Chinese Academy of Agricultural Sciences, Beijing 0008; 2. The College of Life Science, Hebei Normal University, Shijiazhuang 05006; 3. Beijing Enhalor Biotechnique Co. Ltd., Beijing 0008; 4. State Key Laboratory of Freshwater Ecology and Biotechnology, Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan 430072) Abstract: An eight weeks growth trial was conducted to investigate the effects of dietary melamine inclusion on growth performance, physiological response, renal histopathology and tissue residues in Japanese sea bass (Lateolabrax japonicus). The inclusion levels of melamine in experimental diets were 0, 500, 2000, 5000 and 0000 mg/kg (D, D2, D3, D4 and D5), respectively. Each diet was fed to triplicate groups of the experimental fish with initial body weight of (30.6±0.) g. Fish were reared in a semi-flow-through system for 56d, and water melamine contents were controlled < 0.5 mg/l. The results showed that the daily melamine intakes for Japanese sea bass in five treatments were 0, 8.26, 32.38, 80.34 and 48.83 mg/kg w/d, respectively, during 56d trial period. The feeding rate and growth performance were significantly decreased in 0000mg/kg melamine treatment (or 48.83 mg/kg w/d daily melamine intake treatment) (P<0.05), there was no significant difference in feed conversion ratio and survival rate among all treatments (P>0.05); for the whole body composition of Japanese sea bass, no significant difference was discovered in moisture, crude ash or crude protein contents between each treatment (P>0.05); with the increasing supplementation of melamine in the feed, the serum alkaline phosphatase activity (ALP) increased gradually, ALP activity in 5000mg/kg melamine treatment was significant higher than the control group (P<0.05), the serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), total protein (TP), glucose (GLU), Cholesterol (Chol), Triglyceride (TG) and Urea nitrogen were not significantly affected by melamine during 56 days (P>0.05); residues of melamine were detected in the liver and muscle of the Japanese sea bass, 57.9 mg of melamine /kg of tissue (wet weight) were detected in the fish liver from daily melamine intake 48.83 mg/kg w/d groups; 47.63 mg of melamine/kg of tissue and 73.7 mg of melamine/kg of tissue were detected in the fish muscle from daily melamine intake 80.34 mg/kg w/d and 48.83 mg/kg w/d groups respectively; histologic examination of kidney revealed that the kidney was harmed by melamine, but no crystal was found in the kidney. The 56d NOAEL (no-observed-adverse-effect-level) for melamine in Japanese sea bass was 8.26 mg/kg w/d. Key words: Melamine; Japanese sea bass; Growth performance; Residue; NOAEL
