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.
