Effects of different levels of taurine on growth,laying performance,and egg quality of quail for laying purposes
The experiment was conducted to investigate the effects of taurine on the growth,laying performance and egg quality of quail for laying.A total of 1800 one-day-old quail were divided into three groups with three replicates per group and 200 quail per replicate.The diets of quail in each group were supplemented with 0,100,300 mg/kg taurine,respectively.The trial lasted 46 weeks and was divided into two phases,the first phase lasted from 0 to 6 weeks and the second phase lasted from 7 to 46 weeks.The results showed as follows:Compared with the control group,supplementation of 300 mg/kg taurine significantly decreased the ratio of feed to gain in growing stage(P<0.05),significantly increased the laying rate and Haber's unit in laying stage(P<0.05),and decreased the ratio of feed to egg and the rate of broken eggs in laying stage(P<0.05).Supplementation of 100 mg/kg taurine significantly decreased the breaking rate of eggs(P<0.05),but had no significant effects on average daily feed intake,laying rate,and feed to egg ratio(P>0.05).The results showed that the effect of taurine on the production performance of quail was related to the addition amount,and the effect was not obvious when the addition amount was 100 mg/kg.
