In Ethiopia exotic sheep, cattle, and goat breed importation was initiated in early 1944, the 1950s, and 1975, respectively to improve the productivity of indigenous animals through crossbreeding. However, the per capita consumption of livestock products is still below the standard and cannot supply the ever-increasing human population. Thus, this paper reviews the current status of livestock crossbreeding, causes for failure and discusses how it can be implemented for the future without harming the indigenous animal genetic resources. A cattle crossbreeding has led to higher milk production per animal. A two to fourfold increment in lactation milk yield, 47 to 155 days increment in lactation length and 9 to 32% improvement in yearling weight than indigenous breeds were reported for crossbred cattle. Sheep crossbreeding programs using Awassi sheep breed improved the livelihood of smallholder in the highland areas and they start to produce genetic materials with its limitations. On the other hand, the decline in fitness traits (survival and reproduction) is reported for crossbred cattle and sheep. Both dairy and meat goat crossbreeding programs were not successful under the smallholder management system. Generally, the possible benefits from livestock crossbreeding were not fully exploited. The possible determinants for unsatisfactory achievements and poor sustainability were found to be the absence of a well-established breeding plan, lack of feed resources, poor veterinary services, lack of sustained funding, lack of basic understanding of crossbreeding, poor efficiency of reproductive technologies, access to financial credit and low involvement of smallholders in the implementation of the program. Therefore, careful planning considering the feasibility and sustainability, promoting alternative feed resources, improving veterinary services, enhancing the efficiency of assisted reproductive technologies, sustainable financial support and improving the record-keeping system are all vital for successful and sustainable livestock crossbreeding program.
