摘　　要：将45只处于妊娠后期(90～150d)的苏尼特母羊随机分成4组,以不同的营养水平(代谢能:0.20、0.33、0.44、0.86MJ/kgW0.75·d)分组饲养,分娩后进行补偿生长试验,研究妊娠后期不同营养限制程度的母羊在补偿初期(分娩后0～6周)对中性洗涤纤维(NDF)、酸性洗涤纤维(ADF)消化率的影响。结果表明:在补偿初期,各组母羊对ADF、NDF的消化率随着营养限制程度的增强而下降。Forty five Sunit post-pregnancy ewes （90-150d） were randomty divided into tour groups, and offered different nutrition level （ME： 0.20, 0.33, 0.44, 0.86 MJ/kgW^0.75·d）. After parturition,the compensatory growth was studied to investigate the effect of different nutrition restriction for Sunit post-pregnancy ewes on digestibility of neutral detergent fiber（NDF）, acidic detergent fiber（ADF）during the initial stages of nutrition compensatory （0-6 weeks after parturition）. The results showed that during the initial stages of nutrition compensatory, the digestibility of ADF, NDF decreased with the increase of restriction level.
