Although there are a number of Vietnamese native pig (VnP) populations, some are on the verge of extinction, and therefore adequate management and conservation are necessary. In this study, we conducted a field survey of VnP populations and analyzed interrelationships among their characteristics. We also established a relational database for management of field data on these populations. For data collection, we conducted interviews with farmers and visual inspection of 32 VnP populations in 22 provinces of Vietnam, as well as taking photographs of individual animals. Data on the characteristics of VnP populations were subjected to multiple correspondence analysis (MCA). For establishment of the database, normalization and table partitioning were performed to eliminate redundancy and ensure consistency of the collected data items. Passport data, characteristics data, and image data were collected from a total of 1,918 VnPs and entered as a normalized table. Upon MCA, most of the populations were not separated from each other, but the Mong Cai, O Lam, and Chu Prong populations were separated from the other populations. Thus, we have constructed a relational database from comprehensive information on the characteristics of VnP populations.

越南本土猪群的表型特征和关系数据库。


尽管越南本土猪（VnP）数量众多，但其中一些已濒临灭绝，因此需要进行充分的管理和保护。在本研究中，我们对 VnP 人群进行了实地调查，并分析了其特征之间的相互关系。我们还建立了一个关系数据库来管理这些人群的现场数据。为了收集数据，我们采访了农民，对越南 22 个省份的 32 个 VnP 种群进行了目视检查，并拍摄了个体动物的照片。对 VnP 群体特征的数据进行了多重对应分析 (MCA)。在建立数据库时，进行了规范化和表分区，以消除冗余并确保收集的数据项的一致性。从总共 1,918 个 VnP 中收集了护照数据、特征数据和图像数据，并输入为标准化表格。在 MCA 期间，大多数人口并未彼此分离，但芒街、阿林和朱蓬人口与其他人口分离。因此，我们根据 VnP 群体特征的综合信息构建了一个关系数据库。
