Buffalo (Bubalus bubalis) is a major source of milk, meat, and draught power in many developing countries in Asia. Animal cloning holds a lot of potential for fast multiplication of elite buffaloes and conservation of their valuable germplasm. Although the progress of buffalo cloning has been slow in comparison to cattle or pig, several breakthroughs were reported in buffalo cloning such as the production of cloned calves from somatic cells isolated from over one-decade old frozen–thawed semen or from urine-derived cells. Since the initiation of buffalo cloning, several approaches have been tried to refine nuclear transfer protocols. This has resulted in increasing the blastocyst production rate and improving their quality leading to an increase in live birth rate. In this review, we discuss current developments in buffalo cloning, its challenges, and the future roadmap.
