Blood acid-alkali indexes data showed that blood PH and Na+K-Cl content was increasing while dEB added from -154meq/kg to 246meq/kg,the interrelation between Na+K-Cl content and dietary dEB was: Y=41.127138+0.011735X-0.00001494X2 (P=0.0615, R2=0.1866) .

• 血液血气指标测定结果表明，饲粮dEB由-154meq/kg上升到246meq/kg，试鸭血液PH值和Na+K-Cl值逐渐增加，血液中Na+K-Cl含量与饲粮dEB之间存在相关性，曲线回归方程为：Y=41.；127138+0
