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(ME:0.20、0.33、0.44、0.86MJ·kg-1.W-0.75·d-1)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)对饲料中钙、磷以及氮的代谢规律。结果表明,受限制各组母羊在补偿初期,随着受限程度的降低,钙、磷平衡(g·d-1)值呈升高的趋势,氮平衡(g·d-1)值呈下降的趋势。

摘  要:
In the study,forty-five sunit post-pregnancy ewes(90~150d) were divided randomly into four groups,and offered different nutrition level(ME:0.20,0.33,0.44,0.86MJ·kg-1·W-0.75·d-1).After parturition,the compensatory growth was studied to investigate the metabolic laws of Ca,P and N of sunit post-pregnancy ewes of different nutrition restriction level during the initial stages of nutrition compensatory(0~6th works after parturition).The results showed that during the initial stages of nutrition compensatory the value of Ca and P balance increased,while the value of N balance decreased,with the decrease of the nutrition-restricted level.
