【摘要】：幼龄反刍动物的培育质量对其育成后的生产和繁殖性能发挥至关重要.我国幼龄反刍动物培育技术研究与应用严重滞后于猪禽等幼龄动物,在消化生理与营养需求参数、标准化饲养管理、幼畜专门化产品及智能化和设施化饲喂等关键技术环节的理论与应用研究严重不足,制约了我国反刍动物产业的健康可持续发展.建立科学系统的培育技术才能保障幼畜的健康成长.本文围绕幼龄反刍动物培育现状,提出了需重视和解决的关键科学问题:基于营养-基因表达调控与现代组学等技术研究幼畜培育理论;深入探究早期营养调控对后期生长及健康的影响机制;阐明母畜围产期营养调控与幼畜机体健康发育的关系.建议科技界与产业界重视并协同开展相关技术研究,构建"幼龄反刍动物健康培育技术体系",以提高幼畜培育的科学性和有效性.
[Abstract]:The breeding quality of young ruminants is very important for their productive and reproductive performance. Studies and applications of breeding techniques for young ruminants in China lags behind those of young animals such as pigs and poultry in digestion physiological and nutritional requirements and standardized feeding and management. The theoretical and applied research on specialized products and key technologies such as intelligent and facility feeding has been seriously inadequate, which has restricted the healthy and sustainable development of ruminant industry in China. Only by establishing scientific system can we guarantee the healthy growth of young animals. Based on the current situation of young ruminant breeding, this paper puts forward some key scientific problems that need to be paid attention to and solved: based on the techniques of nutrition-gene expression regulation and modern genomics, the theory of young animal breeding is studied. The influence mechanism of early nutrition regulation on later growth and health was explored, and the relationship between early nutrition regulation and healthy development of young animals during the perinatal period was clarified. In order to improve the scientific and effective breeding of young ruminants, it is suggested that the scientific and industrial circles should attach importance to and cooperate with the related technical research to construct a "technical system for the health cultivation of young ruminants".
