养殖与饲料2024年第4期丁酸钠对苏北草鸡生产性能、脂质代谢和蛋品质的影响王曜江苏省江阴市徐霞客镇人民政府，江苏江阴214400摘要［目的］探讨丁酸钠在苏北草鸡日粮中的适宜使用量及其应用效果。［方法］采用随机数字表法将120羽140日龄苏北草鸡均分成4组，每组30羽，每组设置3个重复，每个重复10羽。对照组苏北草鸡饲喂基础日粮，试验Ⅰ组、试验Ⅱ组和试验Ⅲ组苏北草鸡饲喂的基础日粮中分别0.05%、0.10%和0.15%的丁酸钠，试验期为42d。试验结束后测定苏北草鸡的生产性能、蛋品质和脂质代谢的考量指标。［结果］与对照组相比，试验Ⅰ组、试验Ⅱ组和试验Ⅲ组苏北草鸡的产蛋率分别提高了1.69%、2.19%和2.15%，料蛋比分别降低了0.18、0.35和0.28；鸡蛋的哈夫单位分别提高了2.7、4.24和3.7，鸡血清中的总胆固醇（TC）的含量分别降低0.88、1.48和1.21mmol/L，甘油三酯（TG）的含量分别降低4.07、9.42和8.38mmol/L。其中，试验Ⅱ组的综合指标较好。［结论］饲粮中添加丁酸钠可以提高苏北草鸡的生产性能，改善蛋品质，降低血清中TC、TG和LDL-C的含量，在饲粮中添加0.10%丁酸钠的效果为佳。关键词丁酸钠；苏北草鸡；生产性能；蛋品质；脂质代谢EffectsofsodiumbutyrateontheproductionperformanceEffectsofsodiumbutyrateontheproductionperformance,lipidlipidmetabolismmetabolism,andeggqualityofgrasschickensinnorthernJiangsuandeggqualityofgrasschickensinnorthernJiangsuWANGYaoPeople'sGovernmentofXuxiakeTown,JiangyinCity,JiangsuProvince,Jiangyin214400,ChinaAbstractAbstract[Objectives]TheappropriatedosageandeffectsofaddingsodiumbutyratetothedietforgrasschickensinnorthernJiangsuwerestudiedtoprovidetheoreticalreferencefortheapplicationofsodiumbutyrateinfarminglayinghens.[Methods]120grasschickensinnorthernJiangsuaged140-day-oldweredividedinto4groupsusingarandomnumbertablemethod,with30chickensineachgroup.Eachgrouphad3replicates,with10chickensineachreplicate.ThecontrolgroupofgrasschickensinnorthernJiangsuwasfedwithbasicdiet,whiletheexperimentalgroupsI,II,andIIIwerefedwith0.05%,0.10%,and0.15%sodiumbutyrateinthebasicdietfor42days.Theproduc‐tionperformance,eggquality,andlipidmetabolismofgrasschickensinnorthernJiangsuweremea‐suredafterendingtheexperiment.[Results]Comparedwithth...
