A total of 702 1‐day‐old male Jiangnan White goslings were used to study the effects of varying levels of Na⁺ and Cl⁻ on their growth performance and blood parameters. In this experiment, goslings were randomly allotted to nine treatments, with six pens per treatment in a 3 × 3 factorial arrangement, and fed diets with three concentrations of added Na⁺ (0.10%, 0.15% and 0.20%) and three concentrations of added Cl⁻ (0.15%, 0.20% and 0.25%). The purpose of this experiment was to investigate the sensitivity of goslings to Na⁺ and Cl⁻ during brooding to determine the appropriate levels of Na⁺ and Cl⁻ in their feed. The results are as follows: (a) Different levels of Na⁺ and Cl⁻ in the diet, especially low Na⁺ and Cl⁻, significantly affected the body weight (BW), average daily gain (ADG) and feed/gain ratio (F/G) of the 28‐day‐old goslings (p < .05). But Na⁺ × Cl⁻ has no significant effect on water consumption (p > .05). (b) Serum concentrations of urea increased linearly with Na⁺ content (p < .05). Serum concentrations of creatinine (CR) and uric acid (UA) increased linearly with Cl⁻ content (p < .05). (c) Na⁺ × Cl⁻ has a significant impact on the serum sodium (Na) and chlorine (Cl; p < .05). The content of serum Na and Cl increased linearly with increasing levels of Na⁺ and Cl⁻. These results show that low levels of Na⁺ and Cl⁻ had significant adverse effects on the growth of 1‐ to 28‐day‐old goslings. The results of the experiment support a recommendation to supplement the diet of goslings with 0.20% Cl⁻ and not <0.15% Na⁺.
