Abstract: This study aimed to investigate the effects of adding different levels of sodium humate on survival rate and growth performance of broiler chickens.One thousand Kebao healthy broiler chickens were selected and randomly divided into 5 groups，with 5 replicates for each group and 40 chickens for each replicate.The chickens in control group were fed a basal diet，and the chickens in groups Ⅰ to Ⅳ were fed the basal diets supplemented with flavomycin，1.0% sodium humate，2.0% sodium humate，1.0% sodium humate with flavomycin，respectively.The experiment lasted for 49 days.The results showed that compared with the control group，the survival rate of chickens was increased in experimental group，the average daily feed intake in group Ⅲ was significantly increased （P＜0.05），the average daily gain in groups Ⅱ and Ⅳ was significantly increased （P＜0.05），the feed/gain in groups Ⅱ，Ⅲ and Ⅳ was significantly decreased （P＜0.05）.In conclusion，the basal diet supplemented with sodium humate could improve the survival rate and growth performance of broiler chickens，and the optimal supplemental level of sodium humate was 1.0%，and flavomycin was used at the same time had the better effect.
