中文摘要:

      重组技术能够作为改进家畜生产系统的替代方法。在反刍动物生产中，重组激素能够显著提高动物繁殖和生产性能。重组抗原和免疫细胞能有效提高肉类和牛奶产量。重组疫苗的使用也有助于减少寄生虫产生的耐药性，改善动物健康。重组酶和益生菌有助于提高瘤胃发酵和饲料转化率效率。同时，许多重组技术仍处于实验阶段，在使用之前，应仔细考虑这些技术的其可行性。另外，转基因动物的使用和基因组编辑技术的发展拓展了重组技术研究的前沿。文章总结了重组技术对反刍动物性能、健康状况和瘤胃发酵的影响和应用，期望为反刍动物生产的可持续发展提供参考。

英文摘要:

      The use of recombinant technologies has been proposed as an alternative to improve livestock production systems. In ruminant production systems,recombinant hormones could remarkably improve both the reproductive and productive performance of animals. More recently the use of recombinant antigens and immune cells have proven to be effective in increasing meat and milk production in ruminant production systems. Likewise,the use of recombinant vaccines could help to reduce drug resistance developed by parasites and improve animal health. Recombinant enzymes and probiotics could help to enhance rumen fermentation and animal efficiency. Many of these recombinant technologies are still highly experimental. Thus, the feasibility of these technologies should be carefully addressed before implementation. Alternatively, the use of transgenic animals and the development of genome editing technology has expanded the frontiers in science and research. This article summarizes the effects and applications of recombinant technologies on the performance, health status, and rumen fermentation of ruminants in order to provide references for the sustainable development of ruminant production.
