Under natural and well-managed conditions, the buffalo has good reproductive and productive indices. However, embryo production (IVEP) has been used commercially to maximise the number of elite animals. In this species, several factors (donor management, culture medium, semen, conditions, embryo transfer) still affect the IVEP results. In addition, the cost of this technique is very high for this purpose. Therefore, more studies, as well as adequate plans, are needed to achieve this objective efficiently. In this review, we discussed the current commercial status, influencing factors ( and ), and the progress and future challenges of IVEP in buffalo. A total of 81 references were used from 1979 to 2022. The relevant data or literature were searched using the following databases: Google, ResearchGate, Science Alert, Science Direct and PubMed, using the following keywords: buffalo oocytes/COCs, buffalo embryos, pregnancy and calving or live birth rate after embryo transfer. The best maturation, cleavage and blastocyst rates in the production of buffalo embryos were 95.8, 75.2 and 33.4%, respectively. The pregnancy and live birth rates ranged from 22.2% to 43.5% and from 15.3% to 36.5%, respectively, after the transfer of fresh embryos produced to the recipients. This review will help to contextualise IVEP in buffaloes, as well as create an adequate plan for implementing IVEP in buffaloes.
在自然且管理良好的条件下,水牛具有良好的繁殖和生产指标。然而,胚胎生产(体外胚胎生产,IVEP)已被商业化应用以最大化优良动物的数量。在这个物种中,几个因素(供体管理、培养基、精液、条件、胚胎移植)仍然影响着体外胚胎生产的结果。此外,这项技术为此目的的成本非常高。因此,需要更多的研究以及适当的计划来有效地实现这一目标。在本综述中,我们讨论了水牛体外胚胎生产的当前商业状况、影响因素(以及),以及其进展和未来挑战。共使用了1979年至2022年的81篇参考文献。相关数据或文献通过以下数据库进行搜索:谷歌、ResearchGate、科学警报、科学Direct和PubMed,使用以下关键词:水牛卵母细胞/卵丘-卵母细胞复合体、水牛胚胎、胚胎移植后的妊娠和产犊或活产率。水牛胚胎生产中的最佳成熟率、分裂率和囊胚率分别为95.8%、75.2%和33.4%。将新鲜生产的胚胎移植到受体后,妊娠率和活产率分别在22.2%至43.5%和15.3%至36.5%之间。本综述将有助于了解水牛体外胚胎生产的背景情况,并为在水牛中实施体外胚胎生产制定适当的计划。
