This study investigated the effects of substituting fish meal with mussel meal in diets on the growth per-formance,serum biochemical indexes,and antioxidant capacity in young Chinese domestic cats.A total of 12 healthy Chinese domestic cats,aged 6-10 months and with similar body weights,were randomly divided into three groups(n=4 per group):commercial diet control(C1),fish meal-based control(C2),and mussel meal test group(T).The experiment lasted for 30 days.Results showed that mussel substitution did not significantly affect growth per-formance(P>0.05).The T group exhibited a higher apparent digestibility of proteins and fats compared to the controls.Serum analysis revealed significantly elevated alanine aminotransferase activity(ALT,P<0.05)in the T group,while aspartate aminotransferase(AST)activity and the AST/ALT ratio remained unchanged.Notably,the T group demonstrated lower glucose,total cholesterol,and triglycerides(P<0.05).The total protein in the T group was comparable to that of C2 but significantly higher than that of C1(P<0.05).The decreased albumin(ALB)and increased globulin(GLB)levels reduced the ALB/GLB ratio(P<0.05).No significant variations were observed in the total antioxidant capacity,superoxide dismutase activity,or malondialdehyde contents among the groups(P>0.05).These findings suggest that mussel meal can effectively replace fish meal without compromising growth,while potentially enhancing the antioxidant status despite inducing mild changes in hepatocyte activity.
