Abstract: The aim of this study was to observe the role of red clover (Trifolium pratense) isoflavones on ascites syndrome (AS) and antioxidant activity of broiler. Three hundreds broilers were randomized divide into three groups: normal temperature control group, low temperature group, low temperature and supplement red clover isoflavone group. AS was induced by cold exposure, ascites syndrome incidence was recorded. Six birds were randomly selected from each group on 14, 21, 28, 35 and 42 days, ascites heart index (AHI), packed cell volume (PCV), SOD (superoxide dismutase), MDA (malonaldehyde) and GSH-Px (glutathione peroxidase) in serum and liver were detected. The results showed that the incidence of AS was increased induced by cold exposure, treatment with red clover isoflavone attenuated AS incidence, AHI and PCV were decreased, further, red clover isoflavone elevated antioxidant activity of broiler.
