摘　　要：[目的]研究饲粮蛋白质、钙、磷添加水平对生长期固始白鹅日增重的影响。[方法]将270只生长期固始白鹅随机分成9组，每组10只，各设3个重复，其饲粮采用蛋白水平为12．4％～14．5％、14．5％～15．5％、15．5％～17．4％，钙水平为0．7％、0.8％、0．9％，磷水平为0．30％～0．39％、0．40％～0．41％、0．50％～0．52％采用3因素3水平正交设计，比较每组日增重。[结果]结果表明：不同蛋白质水平对生长期固始白鹅日增重影响极显著（P〈0．01），以15．2％（第4组）和15．5％（第5组）蛋白水平增重速度最快，料重比最低；高钙低磷（第5组）水平对日增重影响同样极显著（P〈0．01），但不如蛋白水平影响大；中低钙水平对生长期固始白鹅日增重影响差异不显著（P〉0．05）。[结论]生长期固始白鹅饲粮适宜的蛋白质添加水平为15．2％～15．5％。[ Objective] The research aimed to study the effects of dietary levels of protein, Ca and P on the daily weight gain of Gushi white geese during growth period. [Method] The 270 Gushi white geese during growth period were divided into 9 groups,and each had 10 pullets with 3 replicates.3 × 3 factorial anangement was designed,consisting of 3 protein levels（12.4% - 14.5%, 14.5% - 15.5%, 15.5% - 17.4% ） ,3 Ca levels（0.7% ,0.8% ,0.9% ） and 3 P levels（0.30% -0.39% ,0.40% -0.41% ,0.50% -0.52%）. [Result] The results were as follow：The effects of different levels of protein on the daily weight gains was notable significant（ P 〈 0.01 ）. The daily weight gain was higher and feed gain was lower wizen the dietary level of protein in 15.2 % （group 4） and 15.5 % （ group 5）. The effects of higher Ca level and lower P level（group 5 ） in the feeding stuff on the daily weight gain were notable significant（ P 〈 0.01 ）.But the effects of the middle and low Ca level on the daily weight gain were not significant（ P 〉 0.05）. [Conclusion] The Gushi white geese could grow well when the protein level was 15.2% - 15.5%.
