Profitable goat production is explained by an increased ratio of outputs (meat, milk, flees and skin) per production inputs (labour, feed and management costs). The productive potential of goats depends on their productive efficiency, which is associated with their reproductive rates. Moreover, the reproductive efficiency of individual breeding females determines the production potential of the flock. This paper reviewed the major reproductive performances of Ethiopian indigenous goat populations reported by several scholars under different management conditions. The evidence from the literature indicated that the reproductive performances of the Ethiopian goats ranged from 6.61 to 14.83 months, 11.82 to 28.46 months, 5.47 to 12.07 months, 1.00 to 2.15 kids and 4.72 to 10.2 years for pubertal age of females, age at first kidding, kidding interval, litter size at birth, and does' average productive life, respectively. This indicates that there is considerable variation within and among the Ethiopian indigenous goat populations regarding the aforementioned reproductive parameters. Similarly, some reproductive traits including age at first kidding, kidding interval and litter size at birth have shown potential differences between management conditions. Hence, reproductive performances of the Ethiopian indigenous goat populations can be optimized using improved management, and within and between breed selective breeding schemes.
