摘　　要：本试验研究不同的日粮电解质平衡值（dEB值）对银香麻鸡生产性能和血液理化指标的影响。结果表明：（1）第一个阶段（小鸡阶段）,对于日增重而言,日粮中适宜的dEB值范围为50～300 mmol/kg,其中以200 mmol/kg为最佳;第二个阶段（大鸡阶段）,日增重较好的dEB值范围为150～300 mmol/kg,其中以250 mmol/kg为最佳。（2）在日粮中添加NaHCO3和CaCl2来调节dEB值时,对于血清中的各种无机成分（钠、钾、氯、钙、磷、HCO3^-）的浓度都有不同程度的改变,但并未引起血清中相应的Na^＋、HCO3^-、Ca^2＋和Cl^-的含量发生正相关的变化。不同的dEB值对血清pH值也无显著影响（P〉0.05）。This experiment was conducted to study the effect of different value of dietary electrolyte balance （dEB） on performances and blood biochemical indices of Yinxiang chickens. The results showed that. （1） In the first phase of experiment, the proper value range of dEB was 50～300 mmol/kg for growth, and the best was 200 mmol/kg. In the second phase of experiment, the proper value of dEB was 150 ～ 300 mmol/kg, and 250 mmol/kg was the best one. （2） The concentrations of Na, K, Cl, Ca, P and HCO3^-in serum were altered slightly by dietary NaHCO3 and CaCl2, which were used for adjusting the dEB value. No significant difference in serum pH was observed amond the treatments （P〉0.05）.
