Broilers commonly experience stressors such as coccidiosis, a parasitic infection that results in intestinal damage, malabsorption, and performance losses. The poultry industry is exploring alternatives to anticoccidials for controlling coccidiosis, especially through the enhancement of gut health. Sodium bisulfate (NaHSO; SBS), an acid salt, has been used for many years as a litter acidifier to reduce aerial ammonia in poultry housing. More recently, SBS has shown promise as a feed additive that improves growth performance through enhancing gut health in poultry. Two trials of 1,920 broiler chicks each were raised to 42 d in floor pens. Chicks were randomly divided into 1 of 4 treatments (480 chicks/treatment) on d 0 that utilized SBS (0.3 or 0.4% of diet) or control diets using sodium sesquicarbonate (0.2 or 0.3% of diet) as a sodium source. In Trial 2, birds were challenged with a 2 × dose of coccidiosis vaccine on d 0. Growth performance was measured on d 0, 14, 28, and 42. Each trial was analyzed independently to yield results for non-challenged or coccidiosis-challenged conditions. All data were analyzed with means separation using a Duncan's test. SBS and control treatments with equivalent sodium contributions were also directly compared. Significance was accepted at P ≤ 0.05. On d 28, broilers fed 0.4% SBS weighed more (P < 0.05) than broilers from either control, regardless of challenge status. This effect was sustained in the challenged broilers at d 42 but was not different (P > 0.05) in non-challenged broilers. No differences (P > 0.05) in feed intake or mortality were observed in either trial. Birds fed 0.4% SBS had lower feed conversion than both control treatments for d 0-42, regardless of challenge status. Collectively, these results indicate that SBS promoted growth performance with and without a coccidiosis challenge more than that of sodium sesquicarbonate as a supplemental sodium source. Because experimental treatments were balanced for mineral content, it is possible the sulfate content of SBS influenced these results.
肉鸡通常会经历诸如球虫病等应激源，球虫病是一种寄生虫感染，会导致肠道损伤、营养吸收不良和生产性能下降。家禽业正在探索抗球虫药的替代方法来控制球虫病，特别是通过增强肠道健康来实现。酸式盐硫酸氢钠（NaHSO₄；SBS）多年来一直被用作垫料酸化剂，以减少禽舍中的空气中的氨气。最近，SBS已显示出有望作为一种饲料添加剂，通过增强家禽的肠道健康来提高生长性能。两项试验，每项试验有1920只肉鸡雏鸡，在地面围栏中饲养至42日龄。在第0天，雏鸡被随机分为4种处理中的1种（每组480只雏鸡），处理组使用SBS（占日粮的0.3%或0.4%），对照组日粮使用倍半碳酸钠（占日粮的0.2%或0.3%）作为钠源。在试验2中，在第0天给鸡接种2倍剂量的球虫病疫苗。在第0、14、28和42天测量生长性能。每个试验独立分析，以得出未接种或接种球虫病疫苗情况下的结果。所有数据使用邓肯氏检验进行均值分离分析。还直接比较了钠含量相当的SBS和对照处理。当P≤0.05时认为差异显著。在第28天，无论是否接种疫苗，饲喂0.4%SBS的肉鸡体重均高于任一对照组的肉鸡（P<0.05）。这种效果在第42天接种疫苗的肉鸡中持续存在，但在未接种疫苗的肉鸡中无差异（P>0.05）。在两项试验中，均未观察到采食量或死亡率的差异（P>0.05）。在0至42日龄期间，无论是否接种疫苗，饲喂0.4%SBS的鸡的饲料转化率均低于两个对照组。总体而言，这些结果表明，无论是否存在球虫病挑战，SBS作为补充钠源比倍半碳酸钠更能促进生长性能。由于实验处理的矿物质含量均衡，SBS的硫酸盐含量可能影响了这些结果。
