The aim of this study was to compare the efficacy of butyric acid glycerides (BAG), sodium butyrate (SB) and coated sodium butyrate (CSB) in turkey nutrition based on the growth performance of birds, carcass yield, meat quality, the dry matter (DM) content of faeces, the incidence of footpad dermatitis (FPD), and economic efficiency. A 105-day experiment was conducted on 400 BIG 6 female turkeys (4 treatments, 5 replications, 20 birds per replication). The addition of CSB and BAG to turkey diets improved the feed conversion ratio (FCR, ≤ 0.05) and increased the values of the European Efficiency Index (EEI, ≤ 0.01). The analysed forms of BA in turkey diets increased the concentration of DM in faeces ( ≤ 0.01) and decreased FPD incidence ( ≤ 0.01), which may suggest that all forms of butyrate improved litter quality and inhibit the risk for diarrhoea. The results of this study indicate that all forms of butyric acid can be valuable feed additives in turkey nutrition.
本研究的目的是基于家禽的生长性能、胴体产量、肉质、粪便干物质（DM）含量、脚垫皮炎（FPD）发病率和经济效益，比较丁酸甘油酯（BAG）、丁酸钠（SB）和包衣丁酸钠（CSB）在家禽营养中的功效。对400只BIG 6雌性火鸡进行了为期105天的试验（4种处理，5次重复，每次重复20只）。在火鸡日粮中添加CSB和BAG可提高饲料转化率（FCR，≤0.05），并提高欧洲效率指数（EEI）值（≤0.01）。火鸡日粮中分析的丁酸形式增加了粪便中DM的浓度（≤0.01），并降低了FPD发病率（≤0.01），这可能表明所有形式的丁酸盐均改善了垫料质量并降低了腹泻风险。本研究结果表明，所有形式的丁酸在家禽营养中都可能是有价值的饲料添加剂。
