摘　　要：试验以艾维因肉仔鸡为研究对象,研究早期限饲对肉鸡养分代谢的影响。结果表明:限饲水平为30%时显著降低限饲期间表观氮、钙、磷利用率(P<0.05),补偿生长期间限饲组对表观氮、钙、磷利用率有上升趋势,但差异不显著(P>0.05)。Avian broilers were taken as mater ials to study influence of limited feeding at early stage on nutrient metabolism of broilers. The results showed that when limited feeding level was 30%, the apparent utilization ratios of nitrogen, calcium and phosphor were significantly reduced （P〈0.05）. During compensatory growth period, the apparent utilization ratios of nitrogen, calcium and phosphor in limited feeding group showed a increasing tendency, but the difference was not siznificant.
