摘要： 【目的】探究菟丝子和牛蒡子复合提取物对成年猫尿液理化指标、血清抗氧化能力及免疫指标的影响，以期为菟丝子和牛蒡子复合提取物在宠物饲料上的应用提供理论依据。【方法】将20只体况和年龄相近的成年英国短毛猫随机分为2组，对照组提供基础饲粮，试验组饲粮在基础饲粮中添加3 g/kg复合植物提取物(由菟丝子提取物和牛蒡子提取物按质量比1∶2混合，主要成分为没食子酸酯、槲皮素和牛蒡甙)。每组设10个重复，公母各半，每个重复1只猫。预饲期为7 d，正式试验期为42 d。试验结束后，采血并收集新鲜尿液，以测定血常规指标、血清生化指标、免疫指标、抗氧化指标及尿液理化指标。【结果】与对照组相比，试验组成年猫血清总蛋白和白蛋白水平显著升高(P＜0.05)；血清白细胞介素-1β含量显著降低，而白细胞介素-10含量显著升高(P＜0.05)；血清丙二醛含量显著低于对照组，而总抗氧化能力显著高于对照组(P＜0.05)。与对照组相比，试验组饲粮对成年猫尿液pH无显著影响(P＞0.05)，但显著提高了成年猫尿液总量(P＜0.05)，并显著降低了尿液中钙离子、钠离子、钾离子、氯离子、磷酸根离子和柠檬酸根离子浓度(P＜0.05)。【结论】在饲粮中添加菟丝子和牛蒡子提取物组合物能够增强成年猫机体抗氧化能力和免疫能力，改善尿液理化指标，有助于维持成年猫的健康状态。

Abstract: 【Objective】 The experiment aimed to explore the effects of compound plant extracts (Cuscuta chinensis and Arctium lappa extract) on urine physicochemical indicators,antioxidant ability and immune indicators in adult cats,in order to provide a theoretical basis for the application of the compound plant extracts in pet feed.【Method】 Twenty adult British shorthair cats with similar body condition and age were randomly divided into two groups.The cats in control group were fed a basal diet,while in the experimental group received the same basal diet supplemented with 3 g/kg compound plant extracts (a mixture of Cuscuta chinensis extract and Arctium lappa extract in a 1∶2 ratio),primarily consisting of gallic acid esters,quercetin,and arctiin.Each group consisted of 10 replicates,with one cat per replicate and an equal distribution of males and females.The pre-feeding period lasted for 7 days,followed by a formal trial period of 42 days.At the end of the trial,blood samples were collected and fresh urine was obtained to evaluate routine blood test,biochemical parameters,immune indicators,antioxidant status,and urine physicochemical indicators.【Result】 Compared with control group,the experimental diet increased the serum total protein and albumin of adult cats (P＜0.05).In the experimental group,serum interleukin-1β level was significantly lower than that in control group,while serum interleukin-10 level was significantly higher than that in control group (P＜0.05).Additionally,compared with control group,serum malondialdehyde level in experimental group was significantly decreased,whereas total antioxidant capacity was significantly increased (P＜0.05).Compared with control group,the experimental diet had no effect on urinary pH (P＞0.05),but significantly increased total urine output as well as markedly decreased the concentrations of calcium,sodium,potassium,chloride,phosphate and citrate ions in the urine (P＜0.05).【Conclusion】 Dietary compound plant extracts (Cuscuta chinensis and Arctium lappa extract) could enhance the antioxidant capacity,improve immune status and urine physicochemical indexes,and help maintain the body health of adult cats.
