比较了单硝酸硫胺素、氯化硫胺素和苯磷硫胺在肉鸡中的生物利用度，硫胺素缺乏的日粮中分别添加 1.8 和 1.5 mg/kg 硫胺当量的水溶性盐，或 1.5 和 1.2 mg/kg 硫胺当量的苯磷硫胺，并饲喂 3 个重复组/处理21天。硫胺素溶解度或日粮水平对增重、饲料消耗和饲料转化率没有显着影响。同样，使用硫胺素状态的生化指标（红细胞转酮醇酶活化系数以及血液和肝脏中的硫胺素浓度），水溶性硫胺素盐之间没有发现差异，表明它们具有相同的效力。相比之下，硫胺素状态的生化指标显示苯磷硫胺的生物利用度显着高于水溶性来源。
The bioavailability of thiamin mononitrate, thiamin chloride-hydrochloride and benfotiamin was compared in broiler chickens, A thiamin-deficient diet was supplemented with either 1.8 and 1.5 mg/kg thiamin equivalent as water-soluble salts, or with 1.5 and 1.2 mg/kg thiamin equivalent as benfotiamin, respectively, and fed to 3 replicate groups/treatment for 21 days. Weight gain, feed consumption and feed conversion rate were not significantly affected by solubility or dietary level of thiamin. Likewise, using biochemical indices of thiamin status (erythrocyte transketolase activation coefficient, and thiamin concentrations in blood and liver), no differences were found between the water-soluble thiamin salts, indicating that they have identical potency. In contrast, biochemical indices of thiamin status showed a significantly higher bioavailability for benfotiamin than for the water-soluble sources.
