Fecundity is an important trait for the reproduction of economically domestic animals. Some microsatellites related to the fecundity of domestic animals have been identified. In the current study, we investigated five fecundity related microsatellites, including BM1329, BM143, LSCV043, OarHH35, and OarHH55, which had been identified in sheep. We estimated their diversity and population structure in three high fecundity goats (Jianzhou big ear goat, Jining grey goat, Dazu black goat) and three low fecundity goats (Boer goat, Nubian goat, Inner Mongolia Cashmere goat). The results revealed a high diversity of those markers in the goat populations. The population structure did not diverge significantly between high fecundity goats and low fecundity populations, but it followed the agro-ecological zone and management history. This indicated that the frequency of those five microsatellites did not increase during the reproduction of those six breeds. Therefore, these five fecundity related microsatellites are not appropriate biomarkers for goat breeding.
