The aim of this review is to give insight into the reproduction potential of the Korean native goat(KNG) doe. The mean age of the first estrus in the KNG doe is 141.24$pm$18.l7 days. The length of the estrous cycle was recorded as being 20.58$pm$2.63 days, with the mean duration of estrous period being 17.8$pm$7.3 to 32.9$pm$1.2 h, and the duration of the post-partum anestrous period being 13.4(9 to 18) to 30.1$pm$3.8 days in the KNG doe. The ages at first delivery are 10 to 12 months(56.3%) in the KNG doe. The KNG does are no restricted breeding season, because estrus and kiddings are observed throughout the year. The mean gestation period of the KNG doe is recorded as being 150.69$pm$6.14 days with parities having no significant effect on gestation length. The mean interval between parturitions in the KNG doe is 207.78$pm$1.72 days with parities and birth type having no significant effect on kidding intervals. The mean litter sizes at birth in the KNG doe are 1.69$pm$0.03 heads, and litter size at birth was affected (P<0.05) by parity. The mean birth weight of kid in the KNG is 2.04$pm$0.30 kg with a variety as being 2.28$pm$0.26, 2.11$pm$ 0.30 and 1.64$pm$0.19 kg for singles, twins and triplets over of birth type, respectively. The mean mortality of 635 kids in the KNG is 23$pm$1 % with a variety as being 28$pm$3, 21$pm$2, 16$pm$3 and 46$pm$15 % for singles, twins, triplets and quadruplets of birth type, respectively.
