摘　　要：选择5周龄健康、体重(367.9±4.53)g的三黄鸡(♂)224只,随机分成4个处理(Ⅰ、Ⅱ、Ⅲ、Ⅳ),每个处理4个重复,每个重复14只鸡。Ⅰ为对照组,饲喂基础日粮;Ⅱ、Ⅲ和Ⅳ为试验组,分别饲喂添加3.75‰、5.00‰和6.25‰代谢有机酸产品(以短链的酮酸和有机酸为主)的日粮。结果表明,与对照组相比,Ⅲ组平均日增重显著增加(P<0.05),Ⅳ组料重比显著降低(P<0.05);各处理组对8周龄三黄鸡胸肌率、腿肌率和腹脂率均无显著影响(P>0.05),但可提高血清总蛋白、白蛋白水平,降低谷丙转氨酶含量。提示,代谢有机酸产品可有效地提高三黄鸡平均日增重,降低料重比,并通过调节血清蛋白和酶的水平促进三黄鸡生长,其适宜添加浓度为5.00‰。A total of 224 5-week-old healthy Yellow-feathered broilers with similar boby weight（367.9±4.53）g were randomly allocated into 4 groups （Ⅰ，Ⅱ，Ⅲ and Ⅳ） with 4 replicates per group and 14 broilers in each replicate. Group Ⅰ was the control group and fed the basal diet；Groups Ⅱ，Ⅲ，Ⅳ were experimental groups which fed the basal diets supplemented with 3.75‰，5.00‰ and 6.25‰ metabolic organic acids （based short-chain keto acid and organic），respectively.The results showed that compared with the control group，the average daily gain of group Ⅲ was significantly increased （P＜0.05），the feed-gain ratio of group Ⅳ was significantly decreased （P＜0.05）. There were no significant effects on breast meat rate，leg meat rate and abdominal fat ratio in each group （P＞0.05），however，it could improve serum total protein and albumin levels，reduce alanine aminotransferase content of 8-week-old broilers.Therefore，it could be seen that the product of metabolic organic acids could effectively improve the average daily gain，lower feed-gain ratio of broilers，and promote the growth of Yellow-feathered broilers by regulating the level of serum proteins and enzymes，its appropriate level of adding in diet was 5.00‰.
