Abstract:With the quails as research model,different levels of taurine (0,0.01% and 0.05%) were added to the diets to carefully investigate the effects of taurine on production,immune responses and fat metabolism of laying quails.A total of 108 quails were allocated to 3 dietary treatments.Each treatment comprised 4 replicates of 9 quails.The experimental period lasted 4 weeks.The results showed that 0.01% taurine decreased broken and soft eggs ratio significantly (P<0.05),0.05% taurine increased laying rate,decreased feed convesion rate and broken and soft eggs ratio significantly compared with the control (P < 0.05).Compared with that of the control,0.01% taurine decreased triglyceride and atherogenic index significantly (P < 0.05);0.05% taurine significantly increased serum HDL-C and LPL lipoprotein lipase and significantly decreased triglyceride and atherogenic index (P < 0.05).Results of this study indicated that taurine can increase laying rate and decrease broken and soft eggs ratio in laying quails,taurine can enhance immune function,and taurine can promote fat metabolism through increasing serum HDL-C level and LPL lipoprotein lipase activity in laying quails.
