摘　　要：试验分为5个处理组,25-OH-D3(μg/kg)、VD3(IU/kg)的添加量分别为0、2760,69、0,34.5、1380,34.5、2760,69、1380,每组4个重复,每个重复10只健康艾维茵肉公雏,共200只,研究25-OH-D3和VD3不同添加水平组合对肉仔鸡生长性能的影响。结果表明,各处理组肉仔鸡生长性能均较好,而且相互之间的差异均不显著(P>0.05)。日粮中组合添加25-OH-D334.5μg/kg和VD31380 IU/kg时,肉仔鸡的生长性能最佳。The experiment was conducted to study the effects of diet supplements of 25-Hydroxychole-calciferol and vitamin Dz combined at different levels on growth performance of broilers. Five treatments was designed. A total of 200 male broilers were randomly divided into five treatments, each of which had four repeats.
