Abstract：
The aim of this study was to evaluate the effects of pregnant ewe nutrition on the performance of offspring in terms of meat, wool production, and reproduction. Foetal programming in sheep has focused on several aspects related to foetal growth, postnatal production, behaviour, and immunological performance. Currently, significant efforts are being made to understand the endocrine, metabolic, and epigenetic mechanisms involved in offspring development. Current studies have not only evaluated the foetal period, despite the pre-conception parental nutrition has demonstrated an effect on the foetal, embryonic, and pre-implantation periods and can generate permanent effects in the foetal and postnatal phases. The performance of offspring is the result of interactions between the genome, epigenome, and environmental interventions during conception. Several factors influence the expression of phenotypic characteristics in progenies; however, this study focused on presenting data on the effect of pregnant ewe nutrition alone on foetal growth and the productive aspects of their offspring.
摘要：
这项研究的目的是评估怀孕母羊营养对后代在肉类方面的表现的影响，羊毛生产,和繁殖。绵羊的胎儿计划集中在与胎儿生长有关的几个方面，产后生产，行为,和免疫学表现。目前,正在做出重大努力来了解内分泌，新陈代谢，和后代发育的表观遗传机制。目前的研究不仅评估了胎儿期，尽管孕前父母的营养已经证明对胎儿有影响，胚胎,和植入前阶段，并可能在胎儿和出生后阶段产生永久性影响。后代的表现是基因组之间相互作用的结果，表观基因组,以及受孕期间的环境干预。几个因素会影响后代表型特征的表达；然而，这项研究的重点是提供有关仅怀孕母羊营养对胎儿生长和后代生产方面的影响的数据。
