Abstract

This experiment was conducted to investigate the effects of daidzein on growth performance and its potential mechanism in finishing pigs.Sixty crossbred(Duroc×Landrace×Yorkshire)pigs,weighing an average of 50 kg,were divided by body weight and sex into five treatments with three replicates of four pigs in each treatment.The pigs were fed either a control diet(13.39MJ/kg DE,16%CP)or the control diet supplemented with 5,10,15 and 25 mg/kg of daidzein.The results showed that ADG and F/G tended to be improved as the inclusion levels of daidzein increased.Ratio of CD4+ subgroup to T-lymphocyte significantly increased,ratio of CD8+ subgroup significantly decreased in serum of the pigs fed the diets supplemented with daidzein.Daidzein tended to decrease concentrations of serum urea nitrogen,increase concentrations of serum T3 and T4 and enhance activity of SOD and GSH-Px,but did not affect level of GH in serum.
