AbstractObjective]nodertosudthefetofaddngSpirulinaplatensisinfeedonthegrowthstatusofSanuagchicks.MethodFour groups of feed were set up in the experiment. Without adding S platensis as control group（CK），and the experimental groups were added with 2% （T1） 4% （ T2 ）and 6% （ T3 ）concentration gradients of S .platensis.The chicks with an average initial weightof （34.76±0.50 ）gwere fed，andthirowthefoancemuegadexndialateandrelatedicatorsemeasud.esultesultserify that the content of phycocyanin in S.platensiswas 0.06mg/mL ，and the number of phycocyanin per 100g was 9.79g .Compared with CK，the average daily feed intake，weight gain rate and immune organ index of chicks in the feed group added with s platensis increased，and the diarrhea rate and mortality rate decreased.The average daily feed intake of λ12 chicks increased by 27.90% compared with CK，the body weight increased significantly （ P<0.05） ，and the weight gain rate increased significantly by 64.78 percentage point （ P<0.05 ）;the diarrhea rateof each experimental group was lower than that of CK，and the diarrhea rate of T3 was significantly lower than that of CK （ P<0.05 ）. Compared with CK，the survival rate of T3 was significantly increased （ P<0.05 ）.The spleen index，thymus index and bursa index of T1，T2 and T3 were significantly higher than those of CK（ P<0.05 ）.[Conclusion]These results demonstrated the addition of s .platensis in feed isa good green broodingethdtoigificantlyiprovetdileditakeightiatemueoganidendvialateoficksspl S.platensis with high phycocyanin content.
