Technologies to assist in selecting replacement females

A number of technologies are required in taking the various steps needed to identify the genetically most superior animals to keep as parents or to bring into a herd. These technologies are not always new, and due to changing circumstances, some previously uneconomic technologies may become cost-effective. Therefore, there is need to reconsider the use of previously ignored technologies on a regular basis. In some situations, new technologies are being developed for quite different intended purposes, so it is important that those persons involved in genetic improvement of livestock maintain an awareness of developments in fields other than their own discipline. It is paradoxical that some new technologies may be more readily applicable in developing countries than in developed countries, due to the more limited application of existing technologies in developing countries. A good example of this is the rapid uptake of cellular networks for telephone communication in developing countries, where landline networks have typically been in limited use or in poor condition
