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.
尽管有许多越南本土猪（VnP）种群，但其中一些已经濒临灭绝，因此需要进行充分的管理和保护。在这项研究中，我们对 VnP 种群进行了实地调查，并分析了它们特征之间的相互关系。我们还为这些种群的现场数据管理建立了关系数据库。为了收集数据，我们对越南 22 个省的 32 个 VnP 种群的农民进行了访谈，并对个体动物进行了目视检查，同时还拍摄了照片。对 VnP 种群特征的数据进行了多元对应分析（MCA）。为了建立数据库，对数据进行了标准化和表格分区，以消除冗余并确保收集的数据项的一致性。共收集了 1918 头 VnP 的护照数据、特征数据和图像数据，并将其输入到一个标准化的表格中。在 MCA 分析中，大多数种群彼此之间没有分离，但芒街、奥朗和朱普隆种群与其他种群分离。因此，我们从 VnP 种群特征的综合信息构建了一个关系数据库。
