摘　　要：论文旨在探讨日粮不同的锌水平对0~2月龄鸵鸟生产性能的影响。选用初生鸵鸟120只,随机分成4个组,每组3个重复。试验组在基础日粮中分别添加硫酸锌60、90、120、150 mg/kg,试验期2个月。结果表明：日粮锌添加水平对0~2月龄鸵鸟日增重、采食量差异显著,料重比无显著差异（P〉0.05）;0~2月龄鸵鸟对锌的最佳添加量为60 mg/kg;日粮的锌含量为92.4 mg/kg时0~2月龄鸵鸟达到最佳生产性能。This article introduced the study on the effect of zinc levels in diet on the growth performance of brooding ostriches.An experiment was conducted among 120 day-old ostriches to determine the optimal supplement levels of zinc.The ostriches was randomly allotted to 1 of 4 treatments for 3 replicates with 10 ostriches.The planned supplement of zinc was 60、90、120、150 mg/kg.The experiments lasted 2 months.The result showed that average weight gain,average feed intake was significantly affected by the supplement zinc level for 0 to 2 month ostriches;and there was no difference on F/G ratio（P0.05）.In conclusion,the optimal supplement of zinc for the 1 to 2 month ostriches was 60 mg/kg;when the zinc content in daily basal diet was 92.4 mg/kg,the ostriches attained the optimal brooding performance.
