作者： Shiqi Zhang Xiaoyin Zhang Zhanbo Xiong Kexin Li Yuan Gao Ying Bu Nan Zheng Shengguo Zhao Jiaqi Wang State Key Laboratory of Animal Nutrition Institute of Animal Sciences Chinese Academy of Agricultural Sciences

This study was to conducted to investigate the effect of red clover isoflavones on the health indicated by immune status and blood biochemistry in dairy cows. Sixty-eight healthy Holstein lactating cows were randomly divided into four treatments(n = 17 per treatment) from 5 blocks according to milk yield using a randomized complete block design. No initial differences in parity(2.13 ± 1.21), days in milk(165 ± 21 d), and milk yield(33.93 ± 3.81 kg/d) between groups. Cows were fed the basal diet supplemented with 0, 2, 4, or 8 g/kg red clover extract(RCE) in diet(dry matter based). Feeding, refusal feed weights, and milk yield were recorded three consecutive days in weeks 0, 4, 8, and 12. Blood was collected from the tail vein of the cows on the last day of weeks 4, 8 and 12, 1 h after the morning feeding,and analyzed for hormones, immunoglobulins, inflammatory markers, and markers of liver and kidney activities. The dry matter intake was significantly decreased by 3.7% in the 8 g/kg group(P 0.05). These results recommend the supplementation of RCE at a level from 2 to4 g/kg DM.
