Effects of Dietary Protein and Fat Contents on Physiological and Biochemical Indexes of Cichlasoma man-aguense
摘要
Abstract
In order to study the effects of different levels of protein and fat in diets on physiological and biochemical indexes of Cich-lasoma managuense,450 fish were fed diets with protein levels of 40％,44％,48％and 52％and fat levels of 8％,12％and 16％for 56 days.The antioxidant and biochemical indexes of blood and liver were measured.The results showed that,in the analysis of blood antioxidant indexes,the GSH-Px value of 48P/8F group was significantly higher than that of other groups(P<0.05).There was no sig-nificant difference in T-AOC among all groups(P>0.05).Among liver antioxidant indexes,CAT value in 48P/12F group was signifi-cantly higher than that in other groups(P<0.05)and there was no significant difference in T-AOC among all groups(P>0.05).In blood physiological and biochemical indexes,the TG in 40P/8F and 52P/8F groups was significantly higher than that in 52P/16F group(P<0.05).The AST value in 48P/8F group was the lowest,which was significantly lower than that in 44P/16F and 48P/12F groups(P<0.05),and the ALT value in 48P/8F group was significantly lower than that in 52P groups(P<0.05).In conclusion,this study proves that 48％protein and 8％fat content is the appropriate dietary ratio for Cichlasoma managuense,which can enhance the antioxidant enzyme activity and improve the antioxidant capacity of the fish.关键词
