Abstract: 【Objective】 The aim of this study was to investigate the effects of oleoresin capsicum (OC) on serum biochemical,immune and antioxidant indexes of fattening cattle,so as to provide a theoretical basis for the application of OC in fattening cattle rearing and production. 【Method】 Forty-eight Simmental crossbred cattle in good condition,of similar age (15.5±0.5) and weight (484.73 kg±48.42 kg) were selected and divided into four groups of 12 replicates each with one cattle per replicate in a randomized block design.The cattle in control group were fed with the original diet of cattle farm,and cattle in groups Ⅰ,Ⅱ and Ⅲ were fed with adding 4,8 and 12 g/d OC to the original diet of cattle farm,respectively.The pre-test period was 7 d,and the test period was 90 d.Blood samples were collected at the end of the test to determine serum biochemical,immune and antioxidant indexes. 【Result】 Compared with control group,① The levels of total protein (TP) and albumin (ALB) in serum of cattle in group Ⅱ were significantly increased (P＜0.05),whereas the urea nitrogen (BUN) level was significantly decreased (P＜0.05).②The immunoglobulin A (IgA) content in serum of cattle in groups Ⅰ,Ⅱ and Ⅲ were significantly increased (P＜0.05),and the contents of interleukin-1 (IL-1),IL-2 and tumor necrosis factor-α (TNF-α) were significantly decreased (P＜0.05).The contents of IgM and IL-4 in serum of cattle in groups Ⅰ and Ⅱ was significantly increased (P＜0.05),and the interferon-γ (IFN-γ) content was significantly decreased (P＜0.05).The IgG content in serum of cattle in group Ⅱ was significantly increased (P＜0.05),while the contents of IgG,IgM,IL-4 and IFN-γ in group Ⅲ showed no significant changes (P＞0.05).③The total antioxidant capacity (T-AOC),superoxide dismutase (SOD) and catalase (CAT) activities in serum of cattle in groups Ⅰ and Ⅱ were significantly increased (P＜0.05),while the malondialdehyde (MDA) content was significantly decreased (P＜0.05).The glutathione peroxidase (GSH-Px) activity in serum of cattle in group Ⅱ was significantly increased (P＜0.05),whereas there was no significant changes of various antioxidant indexes in group Ⅲ (P＞0.05). 【Conclusion】 Dietary supplementation of appropriate OC could improve the antioxidant capacity and immunity of fattening cattle to a certain extent.Under the conditions of this experiment,the supplementation of 8 g/d OC in diet of fattening cattle had the best effect on improving antioxidant capacity and immunity.
