| 摘要: |
| 本文旨在研究饲料中贻贝粉替代鱼粉对中华田园猫幼猫生长、血液生化和机体抗氧化作用的影响。选取12只6~10月龄健康且体重相近的幼猫, 随机分为商品料对照组(C1组)、鱼粉基础对照组(C2组)和贻贝粉替代实验组(T组), 每组4只。3组幼猫给予相同的条件饲养30 d, 实验结束测定总饲料消耗量、生理指标和血液指标。结果显示, 贻贝粉替代鱼粉对幼猫生长性能无显著影响(P>0.05)。T组幼猫对蛋白质和脂肪的表观消化率优于对照组。T组幼猫血清谷丙转氨酶(ALT)显著升高(P<0.05), 谷草转氨酶(AST)活性及AST/ALT比值与对照组无显著变化; 血糖(Glu)、胆固醇(T-CHO)和甘油三酯(TG)显著降低(P<0.05); 总蛋白(TP)与C2组相当但显著高于C1组(P<0.05), 白蛋白(ALB)降低而球蛋白(GLB)升高(P<0.05), 致ALB/GLB比值显著下降(P<0.05)。3组间的总抗氧化能力(T-AOC)、总超氧化物歧化酶(T-SOD)和丙二醛(MDA)指标均无显著差异(P>0.05)。研究表明, 贻贝粉替代鱼粉对幼猫生长性能、血液指标等无显著影响, 虽可致轻度肝细胞受损, 但未造成实质性肝损伤, 同时降低了肝脏脂质过氧化水平, 增强了机体抗氧化能力, 是具有替代鱼粉潜力的理想蛋白源。 |

| Abstract: |
| This study investigated the effects of substituting fish meal with mussel meal in diets on the growth performance, 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 performance (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. |
