甜菜碱对奥尼罗非鱼生长、体脂含量及血清生化指标的影响
Effects of dietary Betaine on growth, fat content and biochemical indexs in blood of tilapia(Oreochromis niloticus × Oreochrmis aureus)
摘要
Abstract
750 juvenile tilapia( Oreochromis niloticus × Oreochrmis aureu.s ) were randomly allotted to five groups, and were fed diets supplemented with different level Betaine (0、0.15% 、0.30% 、0.45% and 0.60% ) for 65 d to investigate the effects of Betaine on growth, fat content and biochemical indexs of blood of tilapia.The results showed that tilapia' WGR were 19.52%、 16.63% and 21.38% higher than that of control group ( P < 0.05 ) respectively when tilapia feed were added with 0.30% - 0.60% Betaine; FRC reduced by 25.55% 、20.44 % and 29.93% ( P < 0.05 ) respectively; the HSI reduced by 9.29% 、38.57% and 29.29% ( P < 0.05 ); the contents of TG in Tilapia' s plasma reduced by 66.28% 、55.81% and 80.23% (P <0.05) respectively; the activities of AMY in Tilapia' s plasma reduced by 88.78% 、37.59% and 62.41% ( P < 0.05 ); the contents of ALB and TP in Tilapia' s plasma were improved, the contents of CHOL in Tilapia' s plasma reduced; the activities of LDH、 ALT and AST in Tilapia' s plasma reduced respectively.Therefore, under this research condition, it is suggested that the supplement of Betaine in diets of juvenile tilapia was the best at 0.45% ~ 0.60%.关键词
