Application of advanced reproductive biotechnologies for buffalo improvement with focusing on Egyptian buffaloes

Abstract

Many countries in the world consider the buffalo as a priority animal for the future, since it plays a pivotal role in human food sustainability. Even though Food and Agriculture Organization has termed the buffalo as an important undervalued asset, this species has yet to drive the same attention as cattle. Egypt has a wealth of buffaloes dispersed in small herds all over the country, so the efforts that have been made to improve their genetic background show little return. Contrarily, other countries concerned with buffalo improvement have already used a data recording system in buffalo herds, allowing to achieve a much faster improvement progress. This review intends to survey the existing information on the application of assisted reproduction techniques to improve buffalo productivity. The strength points that may help to improve buffalo production are identified, and the obstacles hindering the genetic improvement of Egyptian buffalo are characterized. Therefore, this work will gather information related to buffalo and compile it for an audience of researchers and specialists to enforce international collaboration for the development of buffalo production. Also, it will open the way for people interested in developing a future vision for buffalo potential, which will be helpful to close or minimize the biological gaps of buffaloes’ researches.
